To anyone wondering, that wheezing sound is just his regulator squeaking. They do that sometimes. He wasn't struggling or panicking or wheezing until he looked at his gauge and saw how deep he was. When you're in deep water like that, you can't tell how fast you're sinking at all. It can feel like you're sitting still, but you could be plummeting. Always keep track of your depth.
Maybe deep dives necessitate heads-up display tech including warnings. Hell, it being 2023, you could even program a tiny computer with your weight, gear, gas, BCD specs etc and have it automatically alert and/or respond at certain limits.
As an ER/ICU/Trauma Nurse, the deeper Yuri went, the more pressure is exuded on the Lung tissue, bronchitis, bronchi, Aveoli. etc. I could hear the expiration wheezing....which is BAD for anyone, getting worse and worse. So many "expert" divers have all the expensive dive equipment, yet know NOTHING on how to use it properly, nor do they understand what the parameters are of each piece of equipment. They think owning all the fancy equipment will automatically protect them from the consequences of them NOT knowing how to utilize equipment properly. And they do not have a basic understanding of the human body and why Nitrogen/Oxygen mixture ratios are so important, and at what depth different ratios should be utilized. Too many divers are clueless on how water temperature affects the way each piece of equipment works in conjunction with the other elements of the dive. It is sad that too many fatalities occur because of divers lacking the knowledge & patience to be an effective diver, whether it be a personal or professional dive event. How sad. Such a waste of valuable human lives.😢❤🎉❤
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. And terrorists (puppets of the Antichrist) who misinterpret verses, out of ignorance and political motivations, and take them out of historical context (just like radical atheists do by the way), don't help either. Thank you very much for your time. Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures. Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement. It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them. (19-22 / Translated by Muhammad Asad).. Salam (Peace) --------
Yeah I remember my dad took a lot of videos on camcorders like this in the early 2000s and a lot of his footage looked like this too, one clip just cuts off before playing a totally unrelated clip. In Yuri’s situation the glitched out tape just makes the whole video and situation a thousand times scarier imo
I almost died here. I followed the descent through the tunnel called The Bells down to the arch (6:57 on the right). It was my 4th real dive, so I was very inexperienced. I followed the dive master and saw him disappearing into the arch. After I made it through the arch myself, I looked around and didn't see the dive master. I didn't have a proper diving computer and the mechanical gauge I had malfunctioned and got stuck at around 11 meters. I didn't know that the arch is already on the verge of 30 meters (max depth of dive), so I assumed that dive master descended further and I can't see him, because of the cliff edge, so I proceeded. A few moments later I felt a strong tug on my fin and turned around. I saw the dive master vigorously showing ascend signs to me. It turned out that instead descending he swam sideways (just like he should have actually) and out of sight. He later showed me his dive computer. It registered a depth of 38 meters. It means that I was another 1.5-2 meters deeper than that. Had I continued my descent for another few seconds, I would have experienced severe confusion due to nitrogen narcosis and sank uncontrollably all the way to the bottom, because of compressed buoyancy control vest. I would have ended up exactly like Yuri.
That's probably one of the most dangerous human instincts in situations like this: when we suddenly lose track of the people we're around, we frantically start searching for them without first assessing our own situation. Sometimes being a pack animal fucking sucks. Happy to hear that your dive master pulled you right back up, I would've 100% made the same mistake as you.
Disasters take seconds, but its rarely one single thing that does it. He went alone and he descended beyond his equipment capabilities, and I dont imagine he had a real plan for a safe descend or ascent.
It went wrong about 2 minutes beforehand. It seems to have only taken moments, because by the time he realised how deep he was and tried to correct, it was already too late. Then he panicks, and he dies. He would have known that in dangerous situations underwater, panic is what guarantees your death. But nitrogen narcosis has been described as akin to being drunk. And at that point you don't always have a choice. I want to go scooba diving, but it's genuinely terrifying. Idk, always a helium mix for me in case of accidental depth. Give no chance of narcosis. Pressure alarms if possible. Full laminated checklist that I'm not touching the water without. So many failsafes. And even then it might not be enough.
@@musickat344 oh 100% sometimes it's not in your control! If I were always in control of my emotions it would be exhausting, and also WAY easier to get by. Cave diving is fucking terrifying. And sometimes you just die
Diving when it’s dark like that - it’s easy to descend without having any idea how deep you are. And if you get narcosis, you lose your consciousness and it’s all over
The final moments of the footage are terrifying. The sheer panic the moment he checks his depth gauge, the silt being kicked up from him struggling to ascend. My heart was pounding. RIP Yuri.
@TH-camReviewsAndTutorials No way he intended to go that deep. He was veey clearly overweighted significantly with how fast he had descended and how much he was struggling at that depth. There is also no reason his BCD shouldn't have worked unless he was overweighted
@TH-camReviewsAndTutorials It looked like to me he was.. well panic might be a bit of a strong word but he sure as hell seemed to relaize things weren't OK. However I have the impression from watching the video and the context surrounding this dive that it wasn't so much the depth itself, but the speed at which he had achieved it. He realized he descended too quickly, so he used the buoyancy device to slow his descent, but to no avail. Also the thing about the airmix not being appropriate at that depth seemed to be a cause for concern. In a way it made me think of another video I watched earlier today about this military dude who died in an instant in a cave dive in the US somewhere.
I went diving in the blue hole in 2009 and it was really scary to go into the sea after looking at the graves that were done to the cliff side, knowing that for so many that has been their last place, and they have taken their last breath in that spot. Our diver coach was extremely strict about certain rules and had us all swim in a swarm of 10 and no one was allowed to go further then 2 meters from his/hers dive buddy. we dove to about 30 meters next to the walls, went around and came back up. it was really a different dive that day
It’s worth noting that Tarek said Yuri asked him about diving the blue hole, but Tarek refused and to take him without actual trimix training. I think it was Yuri’s last day or second to last day of his trip, so he didn’t want to wait and do the training. He did this against Tarek’s advice. It’s yet another really sad tale of an experienced SCUBA diver getting overconfident. This is always a rough video to watch, particularly for someone like me who has a fear of not being able to breathe. Hearing him struggle to breathe gives me so much anxiety.
Yes! I was going to make the same comment. I watched dive talk's video about Yuri and he refused to do the proper training because he was in a time crunch. The whole situation could have been avoided with even a little patience and training
why do did he keep going past 40 meters with normal air? Was that always the plan or did he push it a little too far then get Nitrogen narcosis and then continue diving down?
@@MusMasi the 'gravity' in blue holes is very off and he didn't realise how fast he was dropping. He was sinking twice as fast as he thought. His biggest mistake was his impatience, which ended him before he even got into the water.
It's so weird when they say someone with 400 dives is very experienced. I had somewhere around 8,000 in my late twenties with cave, trimix, wreck penetration, and lots of other training and experience. I was still novice level compared to the serious cave divers I knew.
Lol, every human being who has ever lived would be afraid of not being able to breathe. There's literally nothing special or unique about you and your "phobia".
I get another reason why blue holes are so dangerous - it’s incredibly disorientating: the sudden change in light to darkness, and aside from hugging a wall, you can’t tell which way goes where, especially if you’re becoming affected due to the pressure, nitrogen narcosis, etc.
Tarek is a hero. Helping people recover their loved ones is not an easy job. I've seen divers do it and struggle with PTSS after the operation. It is really hard to find people in a place where they took their last breath, where their heart stopped beating and where the last contractions of their muscles stopped. When people die, their loved ones want to have the body, so they can lay them to rest for their closure. People like Tarek help the family give that closure. And that is amazing.

@@islamisthetruewaytogod6812I'm sure many appreciate this, but I also know that many commenters would see a reply, think it's for them, and then be disappointed. Please be mindful. :)
@@peterguirguess853, does it matter if he earns money with it or not? Body recovery is not an easy thing. You take it way too lightly. Maybe just consider what it does to your emotions. You think it is easy to recover humans? Man, I really have no words for your lack of understanding.
Even tho Yuri’s case has been covered many times, I appreciate that you’ve actually explained what’s happening, how he doesn’t have the right oxygen, him struggling to breathe, his dive computer, him struggling to move around at the bottom, the buoyancy device sound, the panicked moving around. So many folk have included parts of his footage and never explained what’s happening, so I really appreciate the way you’ve covered Yuri’s case and taken the time to explain everything that’s happening from start to finish.
@@ryzezee8543 My guess is Yuri would have been able to swim out himself if he had the right oxygen mixture and buoyancy device rated for that depth. The other diver was prepared to go to that depth and recover a body so he had the proper equipment to do so.
The arch is a big reason why the hole is so dangerous. It provides a false feeling that it is the entrance to the top of the hole because of the sunlight shining through the arch. When you have nitrogen narcosis and you are panicked, you swim for daylight. That arch has killed many ppl
I’m a commercial diver and have probably close to 500 working dives that being said one of the primary causes of uncontrollable descent or ascent is the reduction/increase of buoyancy as the ambient pressure increases/decreases thus compressing/expanding the air bladders in you BC or air stored in a dry suit . As you get deeper it compresses more thus increasing your decent. In a panic a person may inflate them thus creating the reverse effect. It’s exceptionally more dangerous using lift bags that are holding up 100s or 1000s of lbs of equipment for construction. They can drag a diver down or shoot to the surface, flip then drop the equipment back on the diver. The ocean wants to kill you, never forget that.
That's why it's important to sort out buoyancy and weights on the surface. The less air you need to maintain neutral buoyancy, the less pronounced this effect is. They teach this in open water dive training, but I see so many people neglect this on their first dive of the holiday.
What's the alternative to inflating your BCD in such a situation? Ditch weights? And why does it create the reverse effect? I'm having a hard time understanding that part.
@@minimushrom inflating your BCD is the best option but you have to be wary for the reverse effect: you inflate your BCD, you start to ascend, the ambient pressure around you decreases so your BCD will expand in volume, and increase your buoyancy, making you rise even faster, decreasing pressure faster, increasing the volume of your BCD even more, and so on. So when you inflate your BCD, make sure you maintain a controlled rate of ascend, and deflate your BCD as you go up to maintain control. Ditching weights is a last ditch resort. Unlike deflating a BCD, you cannot regain weight once you’ve shed it. Ditching weights will usually put you in an uncontrolled ascend. Beats drowning, but will give you the bends if you come up from an appreciable depth.
@@minimushrom Over inflating in a panic. I realize I'm in an uncontrolled decent, I hammer my inflator valve in my drysuit, I flip upside down as the air collects in my legs and feet, then get drug to the surface like a ballon lol. Being upside down of course complicates things. With a Dive hat if the neoprene on your neck damn is old and worn out the hat can fill with water even further complicating things. I've seen more than once from the surface little boots come bobbing out of the water with a diver on the other end. The added risk of cutting weight in a panic on descent and then your overinflated BC or drysuit takes you to the surface as buoyance drastically increases immediately. As you ascend the air expands making you progressively more and more buoyant also making it more difficult to vent out. I used a drysuit as an example but same concept with BC with exception to air collecting in your feet/legs. There really isn't an alternative other than just being cognizant of your buoyancy and not going into a panic. Even fairly small issues can turn into big ones if someone is losing their shit down there.
@@deepblue1846 Thanks for explaining, that makes complete sense. I had a situation once, where we swam rather quickly to the diving site and instantly went down and about 10 meters deep, where I noticed my regulator is not giving me enough air for my quicker breathing. It felt like I was suffocating. My first thought was "UP!", and I was about to inflate and blow bubbles, but then I realized that I'm panicking and acting like an idiot, so I tried to learn from this instead of going up in a hurry. I took two very slow, very deep breaths and it was really interesting, to feel the panic dissipate in seconds. That was such a valuable lesson for my third dive. I will always remember how I was able to stay in control of my brain.
Fun fact- that lens cover that was added at the start of the dive video was a red filter. Divers add them to their cameras during dives because red is the first color to be absorbed by the water at depth.
Was hoping someone would mention this, I've wondered for a while if the guy who runs this channel is a diver, that makes me think he probably isn't. He's a good storyteller and the channel is great either way, had just been on the back of my mind for a while.
@your problem there’s no way he didn’t “know” that being a certified diver, something else definitely went wrong. Could be as simple as narcosis at that depth, but it sounds like he was overweighted from the start. So he sank quickly and the issues just compounded from there.
@@garstrum4401 what video did you watch, apparently the same one as all the other commentors, one that didn't mention the part where his equipment failed maybe. The inflation of his safety vest, was his ticket back to the surface, it failed to inflate. Can you imagine. Do you dive? I've certainly never had an inflation vest failure. Never considered it. But I'm now looking online for compartmentalized inflation vests...
@@PeterPablo-fq2ps I do dive, but you can hear him inflating after he’s already hit the bottom? Plus I feel like if he was just sinking and bc not working he could’ve just ditched weights (and/or the camera, not sure what dive video cameras looked like in 2000 but I imagine they were quite a bit bulkier and heavier than todays). Idk I don’t recall the video saying equipment failure but agree it’s certainly a possibility.
I’ve dived 60m with air, it was a mistake and I was young and too keen to push boundaries, it never happened again. It scared me so much that I still have nightmares, I hadn’t planned stops for that depth and I was suffering from NN, I don’t know how I lived or even that I didn’t suffer. I was able to make it back to the surface safely. This kind of thing happens easily if you are allowed to dive alone or split from the group.
You can dive to 60m on air that is the absolute maximum recommended limit for various reasons. You can also do no deco dive to that depth,just. The mistake was doing it without experience and not taking the right training
I like that you narrarate these videos in a respectful manner, not playing it up with a scary tone of voice like some other youtubers. This is tragic, and you treat it as such. Thank you❤
I'm a certified PADI OW diver with over 100 dives. In the course this case & others were explained, like the deep dive to the submarine in Australia. Part of the course is the instructors going over deaths to sober us and be aware of the dangers to an otherwise very Zen and easy "sport" to do. Yuri did quite a few things wrong, first by being overweighted, then leaving his buddy. I dove with many divers that love having extra weights, not want to float down slowly, nor practice proper BCD buoyancy protocols. A semi-argument I had with one fellow tourist in Cozumel, was that he wouldn't hesitate to drop his weights to float back up, even though I mentioned that when you panic, the very last thing divers do is ditch their weights. They overinflate then burst their BCDs. Well, we weren't diving off the wall and the local guides let the tourists do what they want if they flash their PADI cards, so... Cozumel reefs are 5m-12m range with wall at 25m. You want to stay far away from the wall. Not much can go wrong at lower depths if you have some experience. Cozumel reef & drift dives are an excellent dive choice for beginners and extremely safe. Just don't do any deep dives until you master your BCD, maybe after 20-ish ocean dives. Personally I don't even like deep dives, as you see nothing. Between 5m & 12m visibility is excellent and lots of life / corals to gawk at, plus, your air tank lasts twice as long.
If you know what you’re doing there’s no reason to descend slowly. It’s usually good to get to the bottom as fast as possible when drift diving or wreck diving to escape the current. Making a slow ascent is the important part
@@chulo1996 Drift diving I agree, I don't do those, unless there's a buoy rope I can use. I need to equalize my sinuses at 5m, so I take my time, maybe 15s. Others like hitting the bottom right off the boat.
@@rileyp1419 It's a "cheating death" mentality. I'm a deep cave diver and that depth is normal, but you are correct that it's often just a hole in the rock and certainly not something worth risking one's life.
Terrifying “found footage.” After having watched that (I couldn’t look away) I’m in awe at how many people are still willing to risk not just their life but Tarek’s as well. That was also narrated so very well. I’m shook.
People care about their own feelings over others. They will scream and cry that others are cowards who don't care about the dead's dignity and that a cultural funeral (whatever is important to their religion, or just having a body to look at) will let the dead 'rest' and comfort the survivor. To me, it is selfish and self-indulgent but I am not mad with grief.
I'm going to guess that the one main issue that all of them suffered from was... not checking their instruments. When you're deep underwater, you can barely tell when you're moving. Especially when it's dark. This is a big huge hole with no clear landmarks, visual cues, or anything if you're not right beside the wall. Most popular leisure/tourist dive spots have lots of things to see, so you don't have to constantly look at your gauges. This is a deep hole with not much else. The thing about BCDs is that you have to CONSTANTLY check and regulate the buoyancy. Because of they way they work, the air compresses as water pressure increases - which makes the BCD less buoyant. In short, the deeper you go, the faster you sink (unless you're regularly checking your gauges and adjusting the BCD). I'm guessing most people didn't realize how fast they were sinking, thinking they were just taking a slow leisurely dive until the ground came up at them and they realize they're suddenly at 80m+. (Typical PADI open water certification is only good to 18m) The same issue comes up when ascending, too. BCDs get MORE buoyant as you ascend and water pressure decreases... which means divers will rocket up to the surface unless they check their gauges and control the BCD. Now they're going to deal with decompression sickness.
I almost skipped ahead when I realized you were going to talk about Yuri, since I have heard his story many times. I'm glad I didn't because I have never seen the footage the way you showed it,and your narration was perfect. This was the first time I actually felt anxious while hearing about his story and watching the video. I caught myself holding my breath and wishing he would stop,turn around, and return to the surface. Well done, as always!
Why is that crazy ? I'm guessing that you don't know anything about diving. Divers going deeper than about 120 ft. have to breath a special mix of air (tri mix) . This dumbass died because he was using regular air. He's a diving instructor for Christ sake. He teaches this to people on the first day of dive class. How deep a person dives is dependent upon their gas mix and equipment. There is no situation in which anybody would dive a new spot without constantly checking their depth monitor. Guy's an idiot, and it's a good thing he is no longer a diving instructor.
I'm Egyptian and I've been to the blue hole several times, but only for snorkelling. I remember the first time staring down the abyss and it was just hauntingly beautiful. The first time I went there I wasn't aware at all of its morbid history, I just innocently snorkelled around the edges and enjoyed the reef and the fish. In fact, dahab and the blue hole are a very popular local vacation spot and it's surprising how almost no one knows how truly dangerous it is. When I found out I was horrified and it made my second visit there much more somber but still hauntingly beautiful. Let's not get into the non existent safety regulations, basically anyone can get in the water and swim around the blue hole with no supervision. So I'm not surprised at all that there are no official records of the dives. But still it's my favorite spot to swim around in Egypt and I wouldn't miss an opportunity to visit this enchanting site again! :) Edit: Senpai has noticed me!!
Hi, advanced open water scuba diver here! So, there were a couple of things I noticed just because I have the context of training. 1) I don't think he had a diving buddy. One of my number one rules is to always dive with a buddy! Your chances of survival drastically increase with a buddy, and there's just no sign of anyone else with him. You would usually hear the other person breathing as well. 2) Regulators just have a squeaking noise that they make sometimes. It happens when you breathe in. His breathing didn't become panicked until he realized how deep he was after looking at his computer. 3) I am amazed that he did not look at his computer during his descent without a guide rope. Guide ropes are used so that you can ease yourself up or down at a measured pace. While ascending, you have to look at your computer to make sure that you aren't going up too fast (decompression sickness), but almost equally as important, you have to look at your computer while you descend - especially when you're diving in a place deeper than your maximum allowable depth, so you don't go too deep. That he NEVER checked his computer until he hit a ledge baffles me. I think with normal air and an advanced open water scuba diving cert, you can only go a maximum depth of 100 ft, which is more or less out of nitrogen narcosis range (it varies from person to person), and you need special air mixing certifications to get the air mixtures that prevent nitrogen narcosis and allow you to dive deeper. Anyway, just some observations. It is truly tragic to lose one of our own, but watching these reminds me of all of my training and safety protocols I learned. They're always written in blood, it seems.
The procedures in scuba diving are indeed written in blood, and once in a while someone will come along and remind us of it. It's kind of the same thing with the high prevalence of open water instructors who die in beginner caves. They go into the caves with no training, without the right equipment, but all the hubris in the world. And die.
Just a couple of small corrections on your video: - @06:50 - the part of the dive map labelled "arch" isn't the entrance to the famous arch on the inside of the blue hole (at around 52m or so on the inside wall facing out towards the ocean). It's a separate feature from the blue hole altogether called the bells further down the coast. It's a chimney like feature with a more or less vertical drop from sea level at the surface which goes straight down and exits around 30-40m facing out into the blue (the ocean). The wall itself that it and the blue hole are situated within go down to depth of I believe around 800m. Once you pop out of the bells, a common diving route is to then do a gradual swimming ascent along the wall until you reach a shallow saddle at about 6m depth which then takes you into the blue hole itself. - The other point to mention was that it's not so much the case that people choose to morbidly go and see the grave stones - it's simply that to do the bells to blue hole dive, you have to walk past them to get to the bells to start your dive. It's a very sobering reminder to not let ego overtake skill, training, equipment and experience. - @10:37 - that thing he's attaching is a red lens filter. They're used in dive photography for colour correction as red light is filtered out by absorption as divers descend. Without them, photos look flat and very blue or green so it effectively restores some of the natural colours that are present underwater. - final point - another reason for the blue hole being so deadly is because of the appeal of the arch. You can see it pretty clearly from above at 40m (the limit for recreational scuba diving) and water distorts perceptions of distance. Lots of divers have gotten into trouble/died because of this factor as they assume that the top of the arch closer than it actually is and that they can make it down there with single cylinders with air (21% O2). Unfortunately, the tunnel the arch opens into requires that divers descend further to exit on the other side of the wall and once you're in there, you're committed. This is where the problem lies as for most people, this route at this depth simply won't leave enough gas to make the ascent and the necessary decompression stops to avoid decompression sickness (aka the bends). Add nitrogen narcosis impairing decision making, increased air consumption at depth, likely an elevated breathing rate due to hard work and adrenaline/stress and depending on how deep divers go, the risk of convulsions brought about by oxygen toxicity from breathing normal air at a high partial pressure...this is what makes the blue hole so deadly. If you dive the blue hole site, it's easy to see the light hitting the arch and think "I could just go that little bit further". Without the right training certifications, buddy/dive team and equipment, it's just not worth the risk. I should also say, for all its reputation, it's actually a pretty boring dive. The same goes for the Belize Blue Hole as someone who has been fortunate enough to have dived both. Aside from that, I just want to say that I'm absolutely loving this channel!
That's some really awesome and useful information. I always look for comments from people who genuinely know what they're talking about. Thank you for your comment. Stay safe on your diving trips.
It is highly probable that Yuri knew how dire his situation was. Especially in the last 1 to 2 minutes of his life. He seemed to be highly panicked and it was also reported that he was also trying to shed all of his equipment in an attempt to surface. Terrifying
@@joroc, he was an open water diving instructor which does not in any way qualify him for this type of dive. Totally different skillset. He most likely didn't understand his situation until he was WAY past the point of no return. In technical diving it is very easy to "paint yourself into a corner" if you don't know what you don't know. A lot of technical diving training covers how to calculate and plan the dive so you don't end up in that kind of "no way out" situation. Yuri was beyond the point of no return for a long time. He finally realized it in the final minutes, but he was already a dead man much earlier in the dive.
@@CL-gq3no IF he was an OWD instructor, he should have known better. As in a lot better, regardless. Believe me. You don't do these kind of dives on air. Full stop. It's not rocket science. The information is out there. The skills and knowledge are taught, and reasons why explained. I expect far better from an OWD instructor, than killing themselves. Watching your gauges, is critical, especially when you cannot see the bottom, because judging speed while descending is very deceptive, even if you are near a wall.
Edit: take note that this advice is 30 years old. As some replies point out the regulations are nowhere close to how they were when I was diving. So just make sure you consult expert and you should be fine. Original comment : tip from an old diver. If you do not have any certification for scuba diving. Do not under any circumstances let yourself be convinced by a local dive shop that they'll let you go diving with a quick few lessons. You should only dive if you were certified by a recognized organization like PADI or whatever smaller ones there are. But never, EVER, accept training that is done on the spot before a dive. Thats a recipe for disaster. Also, I like what one of my first instructors told me about diving. He said unlike other sports. This sport is a sport which you do not do to get in shape. Its a sport that you need to be in shape in order to be able to do it. In the best of situations it doesn't require that much effort. But if a quick current takes you or something bad happens. How healthy and fit you are will be a huge determining factor on whether you survive the problem or it takes you down. What the hell was Yuri doing? For those who dont have diving experience. Doing a descent in open water without the use of a guide rope requires special training. Its really hard to guage how fast you are going down. The fact the first time he looked at his depth guage was when he was near the floor of whatever ledge he landed on seems insane to me.
I hear you pro tip. I have done two "adventure dives" where i was alone with a diver instructor and have not been formally trained myself. The first time was with my brothers friend who was a military diver for most of his life. He was excellent, kept me in 10 meters of water and was attending me and checking my gear, air reserves and communication regularly. It was an amazing experience. My intention after this dive was to get training. it never happened. I went on a second dive with an instructor i did not know. About half way through the dive we started a descent that i was not told about and was very uncomfortable with, I couldn't see the bottom and had no visual of where he was taking me.. He didn't notice for a while that i was no longer following him. We ended that trip and i haven't been diving since that event.
@@mistertubby Wow, I have to say kudos for keeping calm in that second dive. That's a typical scenario where someone with no training might panic and do something dangerous. It boggles the mind that people who call themselves diving instructors would be comfortable brining someone with no certification on a dive. My basic scuba diving training took place over the course of 6 or 8 weeks, with a full weekend certification trip to some horribly cold and muddy lake. Each session something like 5 or 6 hours. Half was theory and the other half was practice in the huge pool. Definitely made me appreciate the potential dangers. One guy actually quit the class after panicking in some exercises in the pool where we had to remove & purge your mask and practice breathing without your mask on. If at the very least the instructor didn't show you how to do these types of things, he basically rolled the dice with your life. If you ever do want to try diving again, look up some classes. You'll have all the knowledge, skills and proper confidence needed to safely have fun.
A buoy with a guide rope attached would be smart there that’s definitely scary. I’m pretty fit but because I am I sink like a rock! With equipment even worse! At 80m idk if I can come out of that alive 💀
@@mario6279 You would need less weights on your belt. But every human being has a slightly positive buoyancy . Which is why divers will wear weights to help sink. But as you go down and your wetsuit and body compress you become less buoyant. Which is also why divers wear flotation vests. Its linked to your air tank, and you fill it or empty it in order to keep yourself as close to neutral buoyancy as possible. A bit like a submarine does with its ballast tanks.
When I was 13, I was diving King Cruiser in Phuket (top of the wreck is about 20m and bottom is 32m) and went to the seafloor to swim under the wreck. The experience was incredible, tens of thousands of fish schooling around the wreck and feeding on the coral ecosystem that grows onto sunken ships. At the time, I was PADI certified to 60ft (18m) and the dive master told everyone to stay at the top of the wreck, except for a few advanced open water divers. I was getting my advanced open water cert the next year, and I have been swimming my whole life so I went straight to the bottom and started swimming upside down to view the underside of the wreck. When I tell you that pressure changes quick, that is no joke. My BCD was barely able to handle neutral buoyancy with my weight belt, and my tank hit the seafloor. Luckily 32m isn't deep enough for oxygen toxicity, but it was a strange feeling to have to swim directly up to get off the bottom. I would definitely do it again because the views were spectacular and I love wreck diving (not the 2m eels though...), but I HIGHLY RECOMMEND never going below 30m without equipment set up specifically for that purpose, especially for new divers. The feeling of being sucked down by pressure is so foreign to creatures that are normally pulled down by gravity that it is easy to panic or lapse judgement. If in doubt, always establish neutral buoyancy each time you descend, because the BCD buoyancy limit can sneak up on you. And please, if you dive a blue hole stay in view of the walls to gauge rate of descent. Nature does not care, it does not think. Only you can plan ahead to keep yourself safe.
My parents were avid divers back in the day, and my mother lost it while diving in a blue hole (I don't know which site it was). She said she just looked into the dark depths and zoned out, and apparently starting descending way too quickly, not realizing what she was doing. My father noticed after awhile that he couldn't see her, then saw some highlighted yellow part of her equipment way below him. He got her before she descended too far and had permanent issues, but she was sick as hell from decompression since she bobbed up past him once she snapped back into it. I enjoy diving, but I usually try to stick to fresh water sites. The ocean isn't for me, other than short sailing and kayaking trips.
My mom (hairdresser) had been asked to come into the hospital to see a clients daughter… She was over 90ft under when her appendix burst … She came up as calmly as possible, still got the bends.. Had to be in a oxygen tank for weeks.. they ended up saving her life but her long blonde hair had been in salt water & then untouched for weeks as she went thru treatments in the hospital. My mom spent days trying to comb it out.. finally, ended up having to shave some parts & gave her a an asymmetrical Bob to cover it up. Everyone was in shock she even survived.
The closest I go swimming is at the recreational centers that has a full size olympic pool and even then, I'm still extra caution. Other than that, it's heck no for me!!
Two things: 1 Redfilters are generally installed underwater so that there is water behind them to correct refraction. Your images will be distorted if there is a layer of air between the filter and the lens. 2 Not to be calloused but this dive did not go "wrong" underwater. It went wrong when he planned his gear configuration. From what the video stated he had too much weight on and even with a fully inflated BCD couldn't gain buoyancy. That means he was over weighted or his BCD was not rated with the lift required to correct his decent. I have seen divers dive with both of these problems for years with no issues HOWEVER cold water at depth will compress the air in your neoprene wetsuit (all air actually) and may turn you into a "dirt dart" then you will descend rapidly until you hit the dirt sometimes you can't do anything about it. Buoyancy control is something that is SO neglected in the training phase because it isn't flashy and takes a TON of time and intuition to develop.
Just bring an extra few weights or even a rock, in a bag then dump them if you want to drop suddenly but come back up. Some people find common sense difficult.
81 meters and still falling because it's goes to 84 in the same shot. That's so tragic. He knew that he needed to have tri-mix for the type of dive that he was gonna do. It creeps me out how many divers decide to do any dive by themselves. It doesn't matter how good or bad you are at diving if you dive alone...you are alone. RIP, Yuri and all others lost in this blue hole.
I'm curious about his kit. It seems like even with his emergency floatation device inflated, he was still negatively buoyant at 80 metres. Even if he had the correct gas mix, wouldn't he still have been stuck on this ledge unable to ascend, or worse, in open water sinking all the way to the bottom?
As a technical diver I found this video a stark reminder of how quickly things can go wrong. I get nitrogen narcosis at around 40m on air and totally confused at 50m. I cannot imagine what was going through his mind at 80m. Trying to make any sensible decisions I would venture to suggest would be impossible.
Honestly it sounds like a good reason not to do any of that. An activity that relies on intelligence to do safely, where the nature of the activity impedes intelligence, is basically a runaway chain reaction waiting to happen. Just like people climbing to altitudes where lack of oxygen makes them irrational. There you are, in the most dangerous place you've ever been, and you've got absolutely terrible judgement as a natural consequence of the conditions there. Seems like a great reason not to go.
@@aluisious Yes it does sound rather stupid. However it is a test of your ability to focus and concentrate to maintain awareness of what is around you and where you are. I enjoy this sort of diving as it is totally distracting from everything else going on in your life. It is a total test of self discipline and awareness.
@@RailingMedia it comes on gradually if you are concentrating you know something is wrong and simple rise. Knowing where your limits are is part of the discipline.
Thank you for this informative video. It is great. About the Yuri incident, there are a few remarks though, which can be better explained: - at 10:30: " Yuri fiddles with the camera, attaches something ... to protect it from the pressure he knew he would experience " This is a red filter and has nothing to do with pressure. Under water videotography struggles with the effect of light being absorbed by water. This begins gradually within the light spectrum starting with red, which is absorbed after only 3meters of water. To compensate for it you use red filters. You also will notice the gain in red hue after he attaches the lense. - at 13:30:: " his buoyancy control would´ve become less and less effective as the pressure increased" No this is not the case. The opposite is true. Buoncy in the shallows is more difficulte as the percentage difference of the pressure increases and vice verca decreases with depth. For example, diving from 0 to 10 meters is twice as much pressure (100% increase) you have to compensate for. The same 10 meters from 70m to 80m only is only a mere 14% increase in pressure you have to compensate for. The pressure for the buoncy jacket requires the same pressure as the surrounding, i.e. 8bar. A standard dive would start with 230bar. So there is no propblem with compensation. - also at 15:11: the equipment he has is too heavy. Yuri is an dive instructor. The notion that he is too heavy is something I would definitly not go along with. As a diver, especially with deep dives you try to be as light as possible, as it allows for less trouble with buoncy. J - at 14:35 "regular air isn´t recommended below 40m" Well there are dive organisations, which do not allow for more than 20m. But the fact of the matter is this. On regular air you can go to 70m before the partial pressure of oxygen becomes toxic to breath, at 1.6bar. And here is the math: 0,2bar Oxygen * (7bar (waterpressure at 70m) + 1 bar atmospheric pressure) = 1,6bar Notwithstanding Nitrogen narcosis and decompression sickness. What was apparent to me is this: - why look for a dive body when you swim past him? As I have often found, to do underwater-vidoes requires a well coordinated team. The guy with the camery sets the pace. Whenever I dove with somebody else they would not wait for the camera to be ready, or the time it took to take footage and we lost each other. It went so far that I declined to dive with anybody else or other than my wife and would not take anybode with me. Yuri found somebody on the street. And as he was fiddling with his setup his dive-buddy is nowhere to be seen. That is bad. No team-play whatsoever. Than at at 17:03:49 (footage) there are two other divers around him at the surface, both yellow fins 17:05:52 (footage) passing a lone diver - blue fins. By the way, none of these other divers you see in the picture are very good. They act like seehorses. Upright and constantly kicking. An experienced diver is horizontal, hardly moves at all and fine-tunes his buoncy, mostly with his breath. - The breathing becomes laboured and hectic - he starts gulping at the end of ever breath at 17:07:02 you can clearly hear these gulps. First I thought it might be a problem with the equipment, so I went back to the beginning of the dive. But in the beginning the sound of his breathing is clear ond relaxed. So it is clear that Yuri was struggling, becoming ever more prominent at around 17:07:00. It is obvious that nitrogen narcosis starts to set in. - Yuri died from Oxygen poisoning What this video completly fails to mention is that Yuri was in the death zone. What is the death zone? It is the depth when oxygen becomes poisonous, at 1.6bar. Please refer to 3 sections above, where the math is explained. 17:03:30 dive starts slowly, divers all around - absoluty no indication of too much weight, as the Yuri is calm and descent is extremely slow 17:04:00 he descends - his descend rate is about 20m/min = (17:04:00 hrs - 17:09:00 hrs) / 93m = 5min / 93m . This is fast but still ok. With a dive so deep you have to account for decompression time, so there is no time to linger. 17:05:52 (footage) passing a lone diver - blue fins, maybe his dive-body? They pass and the other guy is not to be seen again. At 17:06:42 shortly before he is affected by nitrogen narcosis he inflates his jacket. This is a good thing, as it demonstrates, that he his cognitive about his sourroundings, knows what is going on and reacts to it. 17:06:50 Shortly afterwards he starts gulping. The diver is clearly in distress, probably induced by nitrogen narcosis. Taking the projected descend rate of 20m/min into account he is now 60m deep. There is no clear math to it. But I can assure you that you feel the nitrogen from 50m and below. Yuri is now 60m deep and his breathing is affected by it. 17:07:00 the bottom comes into view, about 5m below. Visibility is bad at about 6m. But the bottom drops off and Yuri passes along. His descend rat is still constant at 20m/min but he enters the oxygen death zone. Nitrogen narcosis and oxygen poisoining result in a complete loss of control. 17:08:30 - checks dive computer for the first time: 81.7m he is now well into the death zone. Movements are erratic and diver shows clear signs of distress, loosing orientation, time and cognitiv abilities. 17:08:33 - 83.7m 17:08:42 - 89.6m 17:08:49 - 91,8m. 17:09:00 he crashes into the ground. As an experienced diver would never ever do that. And mind you, no attempt to inflate Jacket - total loss of control. 17:09:03 - depth 93m??? Inflates jacket but does not go up - clear indication that not enough air was used to inflate the jacket. Stops to inflate further, as was required, while body reactions become ever more frantic. Jacket does not burst, as there is no accustic indication for that. No malfunction of the jacket. 17:10:58 - struggles while on the ground, - video breaks off. - Technical problems with the vest - "the jacket burst due to overfill"?!? This implies a faulty equipment, which attributed to the event. The events that transpired lead me to the conclusion that the Jacket during the dive cleary functioned flawlessly. If anything, the burst might have happened when the dead body was brought up and the decompressed air at 90m+ inflated to 10x it´s volume. And these is the chain of events that brought me to that conclusion: 17:06:42: Yuri inflates his jacket when he passes 50m, to compensate for the compression of lungs, jacket, dive-suit. Everthing seem to be fine and he progresses the descend. 17:07:00 60m - Yuri has difficulties breathing, acts ever more erratic. No indication of using the inflateble jacket. 17:09:03 93m he inflates again, but does not ascend. He inflates for 4 sec. This might have been too short. The notion he is too deep and too haevy is wrong. A good jacket for an adult can easily compensate for 25-40kg buoncy. In the beginning, on the surface he was well balanced since the descend is very slowly. So there is no indication that he was too heavy. At 90m+ his buoncy was negativ and the 4sec of inflation was just not enough to change that. At the end it is stated that the vest has bursed due to being overfilled. I do not believe that on account of 2 factors. He does only inflate twice, past 50m (a short burst) and at 90m. The burst at 90m lasted for a mere 4 sec. That is just not enough to make it burst. And then a divemaster has a professional vest. Those vest do have a valve to compensate for overperssure. So it is not even possible to burst it. And like I said it has more than 25kg (250N) uplift capacity, some up to 45kg. That should suffice in any case. I do not want to exclude a technical failure. But the footage indicates that the jacket was just fine. At 50m he inflates and procedes. At this point he was still lucid. Had the jacket shown any malfunction he would have reacted, which he didn´t. The 4sec burst at 90m was just too feeble an attempt. The prior clear indications of nitrogen narcosis combined with oxygen poisoining account for the inabilaty to react properly. From 17:08:30 on, when he checks the computer which indicates more than 80m he does nothing to stop the descend - no inflation of jacket. He goes ever further and his cognitive abilities are impared. Also, you don´t hear any burst. And it does not burst as the diver drops ever deeper, since the pressure compared to the outer pressure decreases, relatively speaking. So NO, there is no indication that this accident was due to technical failure. If the report is true though, that the jacket did indeed had signs of a burst upon retreaval, there is one logical explanation for it. It must have happened when they lifted up the body. Let´s say he has like 7ltr of air in his jacket, at over 90m. This would expand to over 70ltrs on the surface. I suspect the retreaved the body from the ground, brought him up and at some point the buoncy was positiv at which point they would let the body go by itself, which caused a rapid expansion of the Jacket and thereby caused the burst. Summary: There was no proper coodination with Yuri´s dive-buddy. They did not know each other and might have had different expectations and a different level of experience at the projected depth. Then it was an unfortunate combination of nitrogen narcosis, combined with oxygen poisoning. So, one error played into the next which led to this unfortunate, causal chain of events. It was human factor, no technical malfuction.
As a diver I ask myself how that happened. Okay, it was back in the year 2000 - but wasn't it usual to check the depth in those days? What was his plan? How deep wanted he to go? I can't imagine, that a divemaster cannot control his descent and stop sinking deeper at 30 or 40m.
He would have been trying to dive the arch, which is at 60m.A DM, just qualified has little experience,they're normally young and dumb, experienced ones are worth their weight in gold.Most of the fatalities on that dive are caused by over confidence and bad practice, ie diving on a single tank, not used to strong narcosis etc.Very avoidable sadly. @@DerOetzmann
Why is he going deeper and deeper and didnt check his depth much earlier? What was his intent during the dive at all? I don't understand how you put yourself at risk that way.
Yuri’s video is equally terrifying as it is just sad. Such a simple mistake of diving down too far and being unable to ascend, I can’t imagine how scary that must have been. Unless you’ve scuba dived it’s hard to describe the feeling of depth… I’ve been a diver since 2015, the deepest dive I’ve done is down to roughly 35m and even that felt like a long way down, to the point the water becomes murkier and green, looking up you can’t make out the ripples or waves of the surface, you feel like you’re just in an open abyss. So I cannot imagine being as far down as Yuri was, entirely alone, in the dark, probably knowing you’re going to die down there, so incredibly sad. ALSO: Sean I’m sorry if you’ve already made a video on it, but have you considered telling the story of David Shaw? His story is very interesting, there’s a documentary about it on YT called “Dave’s not coming back”, highly recommend.
Hello fellow diver, a friend of mine was a military-diver in the 90s, and they experimentet with oxygen-narcosis. they went over the limit alone and then got recovered by their colleagues. he said its like getting 1-2 bottles of whiskey in your head at once, its a big freakin hammer and you basically feel nothing anymore. so on the bright side its probably save to say, that you dont feel scared when you hit 80meters. looks like he is super dizzy, not realising whats happening, doing one thing he can and then the mind just wanders off i have reached 45meter with oxygen, by not breathing past 35m and just tipping the ground of the coean and getting back up, so i cant really verify it, but the guy stopped counting past 5.000 dives so i trust him on what he experienced
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. And terrorists (puppets of the Antichrist) who misinterpret verses, out of ignorance and political motivations, and take them out of historical context (just like radical atheists do by the way), don't help either. Thank you very much for your time. Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them). Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI). Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy. Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful. Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI). Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad). Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning! Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures. Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement. It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them. (19-22 / Translated by Muhammad Asad).. Salam (Peace) --------
@TheSilentpulse it's either oxygen toxicity, or nitrogen narcosis. Nitrogen narcosis hits most people slowly after approx 40mtrs. Fairly harmless if you are aware of it, and resolved by ascending to shallower depth. Oxygen toxicity has to do with the partial pressure of oxygen due to depth, and we aim not to go deeper than 56 mtr with the normal 21% oxygen. Symptoms can be like an epileptic attack, very dangerous. (Instructor/over 3500 dives)
I've dived the Blue Hole in Dahab. It's stunningly beautiful, but naturally dangerous. It's safe as long as you stay alert to that danger, are properly trained and follow the protocols - including keeping a close eye on your gauges, because it's otherwise impossible to judge depth there. I have a friend who is a hardcore technical diver (tri-mix rebreather), who told me he has been to the bottom of the Blue Hole a few years ago. He saw a couple of the unrecovered bodies on the way down; nothing but skeletons in wetsuits, slightly inverted by the little bit of air left in their tanks. Haunting.
@@simonforfan I believe they were mainly talking about the difficulty gauging depth. A lot of general recreational diving happens in locations where you can mentally keep track of your depth based on reference points in your surroundings, or the dive will be centered around a fixed goal at a certain depth (for example, ship wrecks are at a set depth that you'll know in advance, so if you're above it, you know you're above whatever depth it's sitting at). In those cases the main risk isn't going too deep, it's staying on top of your air and decompression stops so you don't end up with the bends. Because the Blue Hole has lower visibility and the ocean floor is out of sight, there's no good reference point to judge your depth by. Going too deep is a risk that compounds on itself because the deeper you go the less buoyant you become, and if you aren't paying attention and don't realize you're sinking you won't realize you need to adjust your buoyancy, causing you to sink faster. If you do go too deep, staying calm and keeping a clear head is the first step in correcting it, but the inebriating effect regular air can cause at deeper depths works against that. When you panic, your breathing increases- worsening the effect- and it also makes you more likely to make additional mistakes that could endanger you further. If you are aware that those risks exist, know that you can't rely on your senses and need to be regularly checking your gauges, you're unlikely to end up going too deep in the first place, or can catch it quickly and correct yourself before it becomes truly dangerous. You'll also just generally be better prepared for what to do in that situation because you thought about it in advance, so you'll be less likely to panic.
It's not more or less dangerous than diving any other spot with essentially no bottom. Unless you attempt to do stupid shit and dive beyond your training you'll be fine.
i only dived like 10 to 15 times, and the last time was in egypt actually vey near that exact blue hole. i got drawn away from my group by current on normal air, according to my depth gauge and friend i dropped to like 40- 50 ish meters in depth, i dont really know what i did, but i lost a weight in the process, and if it wasnt for my friend stopping me i'd have swam up to the surface. and it wasnt the darkening of the water, or my friend growing smaller that scared me, it was my changing mind state, and only a second long feeling of "this is fine, just go with it" it almost felt like when i used to work in a kitchen as a teen, and i would do whippets with nitrous when i was alone there and bored. Honestly i think it was my experience with getting high on laughing gas that helped me catch my bearing and act fast enough to survive that day.
*I'm honestly glad they didn't go on to be "professional instructors/guides" in that area.* So many others would have lost their lives too, considering they both lost their lives that fast. Whether it was their fault or the local tank fill shops. If they died that easily they would have just gotten others killed. I'm very sad they lost their lives, but that doesn't mean they should have been guides/instructors for other people, many of which would be newer and less experienced and less capable than them. I feel extremely bad for them, and far far worse for their families. However I still feel if that happened to them they shouldn't be the heads of a tourist diving agency that takes people to the hole. Anyone who cares about human lives should think that as well. I know I'll get hate for this, but I don't care to be honest. If you can't keep yourself safe you absolutely can't keep a group of divers safe, not when plenty will have zero experience in the hole.
I've watched a lot of this type of content. "scary true stories" of caves, divings, etc., and yours is by far the best. I think what I love most is that you include several stories in most videos and you only report on the story and don't embellish like others do. You do a really great job and I love listening to these stories, as tragic as they may be. Thanks for the good work.
Me and my brother are somewhat experienced drivers, both with advanced open water PADI certification. My brother loves photography and I can tell you that at 10:30, what Yuri is doing is attaching a lens to the camera so it retains color as he goes down, which is why it's red. Color loses its vibrancy the deeper down you go, and red is the first.
Yep. I did a bunch of diving some years back and enjoyed video and photography. I still have the rig and the lights. Red light wavelength does not penetrate through the water as deep as other colors do, that’s why it looks so washed out. So you have to add it by adding a red filter. Anyway, a haunting video of Yuri. I shudder at some of the stupid things I have done while diving but survived.
yuri’s scuba diving video was so stressful it’s insane. it got so dark so quickly and i can’t imagine how scary it all must have been once the reality of what happened set in. i hope he wasn’t aware of it for too too long
10:34 the camera is undoubtedly already in a waterproof housing. He's attaching a red lense filter. This helps underwater shots look more correct the deeper you go under. The blue light of the water naturally filters out the color red as you dive down deeper. A red lense filter will help add that spectrum of color back and keep underwater shots from looking dull and muted.
Yuri case always freaks me out. I’ve seen his video before I really liked the way you presented it.the sounds of his breathes etc. give me a sense of deed
Yes. His camera and equipment did him in. Must focus on the dive, not camera. Also overweight can make bouncy a little more challenging. You have to be constantly aware of your depth, 5 seconds and you can be 10 meters lower. I was focusing on some white tip sharks at the bottom and before I knew it, was at 30 meters (only open water certified at that time). Depths are deceiving there and watch your PO2.
Watching his death footage really stuck with me, because it shows how quickly things can go south. One moment he was just swimming around in the bright blue water, two minutes later he is lying on the sea floor, surrounded by darkness and kicking up silt while drowning. A really bleak and dreadful way to die. It's shocking how suddenly everything happened and how this could happen to an experienced diver. It really made me respect the ocean even more and opened my eyes to the fact that recreational diving is really damn dangerous. Obvious in hindsight, but I never thought of recreational diving as particularily hazardous, it's a tourist activity after all. But now I know better.
I had already seen Yuri’s footage but with the voiceover and explanation it is much more eerie and heart wrenching. RIP all divers who lost their lives in the Blue Hole.
I have nightmares about being in the deep dark blue sea with nowhere to go and no direction to turn to and wake up in the most horrid panic and sweat. Now I've just watched this, definitely gonna have another episode tonight.
Thalassophobia (from Greek thalassa θάλασσα, "sea", and phobos φόβος, "fear") is the persistent and intense fear of deep bodies of water such as the sea, oceans, or lakes.
I can not go in water without water shoes.... for some reason thats my only fear with water, deep water, rivers, ponds and lakes.. gotta have water shoes or flippers.
I've seen this footage before, but it scares me every time. Still one of the most terrifying videos I've ever seen. That water was so dark, he must've had a moment where he realised he was finished. I can't even imagine what must've been going through his mind, gives me the chills.
i was a dive instructor and dived the blue hole (not the arch, 30m max) a few dozen times with guests. i did the arch (what you call "exit to ocean" in your drawing) 5 times, 3 times solo, with tec equipment, but on regular air. i think you didn't do a great job describing the layout, the appeal and the danger of this divesite. The main appeal and reason people die is, they do the arch (>52m, tunnel) without qualification or equipment. its a connecting "tunnel" from the inside of the blue hole to the open sea, at minimum of about 52m, but open on the bottom to 150+m. Its absolutely stunning to dive through that arch, its like diving into darkness and then emerging from tartarus into the light and life of the red sea. its just a bit too deep for regular divers, but also, just in range, sometimes in view. a huge temptation. give some bakshish to the right diveguide and he'll take your owd-noob on a 12l tank. boom. gone. what happened to yuri could have happened at any 100m+ divesite. or maybe he was initially looking for the arch?
This is the comment I was looking for. Capital letters would improve the readability of your large message. It took me a while to decipher “owd-noob”, I suspect you meant “OWD-noob” as in, Open Water Diving Newbie. Anyway your message is ironic bc I found this by far the best explanation of the blue hole & arch yet, imperfect as it is. This is the first time I’ve seen this illustration. Everyone else uses the same low res 2D graphic. The illustration here isn’t much better but it at least gives a comparison between it and the common one. Someone needs to do a 3D rendering or at least primitive 3D drawing to illustrate how this hole connects to the arch, and why is it even called an arch? Is it just a tunnel? All tunnels have an arch for a roof, nobody calls them an arch? PS: I’ll give you some bakshish to re-enable your device’s autocapitalization
Thank you for saving me the time and trouble of having to watch the whole video. Which seemingly could be quickly summed up by noting that the vast majority of all of these deaths are due to people being careless or outright reckless and exceeding the limits of their equipment and/or training. Sad but wholly unsurprising.
Thank you for commenting, Dom. Ive never been diving so I have no idea of what "Blue Holes" where and what made them so dangerous. Saw this video's thumbnail a few times on the front page and felt like it was time to watch it.
I am sure my local dive instructor said when I dived here. If your bubbles start going down instead of up swim backwards otherwise you're on an uncontrolled descent. Great dive sight. .
@@thelanehunterdevon1664 what's happening that cause the bubbles to appear to go down? Lost the bearings of down and up? Like someone in an airplane with no visual indicators?
As a diver these videos and stories remind me of one critical thing about SCUBA diving - we are not supposed to be there, underwater that deep. We put ourselves there and we prepare and plan so we are able to come back and tell our stories. Always stick to a coherent dive plan, always keep close to your dive buddies, always keep an eye on your depth and air gauges, always err on the side of caution.
As a commercial diver I can honestly say that deep water is truly unforgiving. If you don't go into the water with the proper amount of respect and careful planning, you could end up like these people. Also I think a video on people who have died due to "delta-p" while working on pipes and dams underwater would make a great video. Imagine opening a 12 inch pipe 60m underwater and being forcefully sucked into it.
Hey, I just bought an open water scuba diving course, watching these videos is a little unsettling but they are good lessons. Was wondering if you had any advice for safety or just expanding my SCUBA experience.
@@ohhpiratenever dive alone. Always dive with someone familiar with the local conditions. I would also say keep track of your air and depth and where you are. It's easier to get separated than you think!😅
I've seen a video on this somewhere. Can't remember the channel. Maybe a Simon Whistler or Mr. Ballen vid. If it's the one I'm thinking of they get sucked in and have an air pocket and i think only one or two made it out?
@@ohhpirate Just pay full attention to your certified dive instructor and follow what you'll be taught. Then continue diving safely to build your confidence but keep your respect for nature by not getting cocky. Learning to dive is the best thing I ever did: ~2000 dives and I've never had any dangerous situations.
@@tomkagi3903you can have bad luck... I was doing a deep dive course with a friend who was one of my regular buddies. At 40m depth my breathing equipment stopped working properly, it just kept blowing air out at an incredible rate. It was painful on my throat, put it 20cm beneath my mouth so I could simply breath the bubbles. I lost 5-10 bars of pressure per second. Due to the rapid expansion it also turned extremely cold, my backup breather was useless because of that cold. By the time I was 5-10 seconds from having an empty bottle at 40m depth my buddy had his backup breather and gave it to me. We held each other tight (we had plenty of emergency training together) and went to the surface again with proper decompression stops. All was ok, but it was a very dangerous situation. It went from everything ok to very dangerous in a very short time. We did very regular emergency training together and nobody panicked and that resulted in a good outcome. Just some bad luck with equipment failure.
I've dived in Dahab twice and I think it's as mentioned, the fact that it's so easily accessible from land and that it transforms from the sort of leisure diving any occasional vacation diver is accustomed to, to something entirely different very rapidly if one doesn't pay enough attention. As pointed out, on air you get narced pretty quickly when descending, and in this specific place you could potentially go from a bright, safe place where you can surface at any time to being narced out at a depth where you may not have enough air to safely ascend in seconds, if you're even able to get your buoyancy device to cooperate. As for experienced divers dying there as well; yes, that's true, but in many cases they were people who had made a lot of not so complex dives, many not being on trimix, using single tanks of air and using simple BCDs, all of which are fine for reef diving at 20 meters, but not for deep dives. As far as I know there are not many experienced technical divers who were prepared for going deep who have perished there.
I dove the Blue Hole about 6 years ago. I was wary of diving regulations and equipment in Egypt, so I spent several days beforehand in Eilat (Israel) brushing on my skills and making sure I knew how to thoroughly evaluate any equipment I'd be using and that I felt better about being able to fend for myself. I'm glad I did. Some of the equipment I got even from a reputable dive shop was janky and my dive instructor (who dove in wearing denim shorts and a tshirt) paid very little attention to me in the water and I basically spent the time trying to keep up with him. Would have been very easy for something to have gone awry. It's an interesting dive site for sure (and Dahab is a really cool spiritual/hippy town) and I'm glad I did it, but to be honest the diving around Sharm El Sheikh is superior by just about every measure. Between the Tiran Straights and Ras Mohamad, the quality and variance in diving conditions is by far and away the best i've experienced.
I believe several people tried to talk Yuri out of diving the blue hole as he wasn’t certified for closed circuit breathing. I don’t dive but even I know you don’t dive to that depth on oxygen. He made the same fatal mistake so many people make when wanting to try something new, they’re in too much of a hurry.
Man this is humbling. I was lucky enough to be certified through NAUI in a course at my university and our research dives were only in caverns. They put a huge emphasis on only to diving in terrains you were trained in and all of mine have been in caverns. Been pretty confident that caverns were the more difficult terrain but the false depth perception that comes with open water is no joke. Always dive with a 1-on-1 buddy!!!
What a sad story for Yuri. When I was training to become a diver there was a story about a couple of boys who went to Kullen to dive. Kullen is a peninsula located in the northwest of Skåne County, Sweden. One of them wanted to free dive and there are places where it is very deep so he had taken a lot of weight with him. As you have probably guessed, he didn't come up again - he sank really hard - probably got an ear squeeze on his way down into the depths. Poor boy. I tried it once during training in the swimming pool where I just for fun had twice as much weight as I should have and I landed on my ass a few seconds later. It hurt like hell, but I physically understood how dangerous it actually was to be overweight. As a freediver, I have used weight to descend, but the last deep dives I did more controlled. Respect the element and be careful out there.
1:29 What is unsettling as well and must make Tarek’s work that much harder, is the fact that not all bodies have been recovered. Some families have expressed their wish to let them rest where they have fallen. I saw a video last year that showed the skeletonized remains that litter the bottom, and some fresh bodies as well.
100% of divers in blue holes wear a neoprene wetsuit. So there are zero skeletons at the bottom of this location. You are just repeating an urban myth that’s not even feasible. Neoprene wetsuit material will contain a body for decades before the material breaks down. You paint a morbid picture but it’s as false image
I know you were concerned about covering Yuri's story since it was so famous, but I'd never heard of it. So I appreciated this. Honestly I think you should eventually cover the most famous incident involving cave diving (the rescue part at least). The Thai kids soccer team. Yes everyone knows the basics but you do very in depth videos and I think you could make it in a way that really goes into detail that few others would cover. That would make it stand out.
People claiming it happened so fast are missing the whole point that he deliberately overloaded himself to go down fast. His descent was very intentional with the idea to do a "bounce" dive I guess so he could brag about how deep he went. The odd part is how ill prepared he was to dump weight and how he neglected to check his depth during his descent. They say overconfidence is a slow and insidious killer. Well it picked up the pace for him.
That’s a crazy video - 81 metres is seriously deep! As others have commented, it’s so deep that the normal buoyancy techniques don’t seem to have worked - plus he may also have been in serious distress owing to the physical effects of being so deep with just normal oxygen etc. Perhaps an issue is simply it’s so dark that divers may not realize how deep they are going without visual cues if they aren’t systematically checking their dive computers
Basically the only way to ascend in that combination would be to throw away your lead and hope that your stamina of kicking to slow you down will be enough to keep you barely alive for a decompression center. But coming to such terms at a depth that prohibit any reasonable thought is already a low chance. And then even with reason, you will know that your chances are low.
I for one have never seen that fotage before. So I hesitantly say thanks for including it. Thanks, because it was very interesing and eyeopening. And hesitantly because... well. That's probably not hard to figure out. Anyway. I only found your chanel a week or so ago, and I love it. Have been bingeing a lot of your videos. Never found much enjoyment in videos about cave diving/exploring since it felt mostly like one cave is just like other caves, but you make it really interesting and I'm having fun (among all the death) learning about different types of caves, how they look and their different challenges. Being european I also appretiate you including the metric system. So many videos just use the american system, and I'm left with just a vague idea of how big/small something is. Also, you could probably read the phone catalog and it would be a nice listen. Your voice is really pleasant. Thank you for making such great videos! Can't wait for more! :)
His problem started at the beginning. Screwing with equipment, bouncy control, switch on regulator possibly in “closed” position, experience. This is a very dangerous dive (like many around the Red Sea). Do not dive them without a guide, no matter how much experience you have. This includes Trimix divers. A professional guide knows the environment and will give you an added measure of safety. This is the first lesson you learn in open water diving. After you are use to the site and informed to its conditions, you are prepared to dive safely. I’ve dove this site. Quite an amazing place. Sad for these divers who lost their lives.
Losing track of your depth in deep, clear water is very easy. I've dove the wall off Little Cayman multiple times, and I have accidentally sunk from 70 to 100 feet without noticing, especially since I also tend to dive a little heavy. Thankfully it was a ten minute non-incident, but it really does come at you fast.
That happened to me when I was learning to dive because I saw a truck on the sea floor & I thought it was closer than it was. Luckily when I looked up & saw my instructor and my mother frantically gesturing at me I corrected my mistake.
In this video you can easily see he is diving very quickly. It is not difficult to spot, it is hard to process. Divers tend to not be very bright which is why they don't notice the indicators that allow one to estimate the speed, in the camera it is extremely visible based on the "white dots" floating.
I think the filter attached to the camera was a red shift filter. Especially before editing software became as prevalent as it is now, deep water videographers had to use some tools to properly represent colors at depth. Otherwise, everything slowly shifts blue as you descend and the video tends to lose a lot of its striking contrast.
This place is like Mt Everest except in reverse.. The fascination, the potentially fatal outcome, and the actual body count all have eerie parallels to Everest.
I live in Egypt and was in Dahab last week. There's a big rock where people's name plates are plastered there to remind people how dangerous it is. Otherwise snorkeling there is wonderful I never get enough of it.
My heart sank when I saw him over 80m down with just regular air. At that depth he was probably dealing with both Narcosis & Oxygen toxicity, which I can only imagine is one of the most terrifying things they could experience… then his buoyancy control ruptured…. That’s when you’ve gotta know you’re too far to go back.
When Yuri first checks his depth gage it says 81 meters down. He pulled it out of camera view for 2 seconds (based on the camera screen time indicator) when he looks at it again it then displays 89 meters down. He begins to panic, because he knows he's in trouble. So apparently he was sinking like a rock, while thinking he was making a controlled dive? 2. Why didn't his dive partner grab his leg and warn him that he was going too deep? 3. If was an experienced diver, he should have known that pure oxygen would be ineffective at a certain depth. I apologize to all on this thread if it sounds like I'm "Monday morning Quarterbacking." I just discovered this channel a week ago and, I'm ADDICTED! When I was a boy, my father took me to see JAWS, 1975, never stepped into the ocean since. And I loved summer's at the Jersey shore! God I'm old.
Very good video. As someone who has always wanted to go scuba diving and isn't aware 9f these invisible dangers, this video and others like it could be saving lives
I’ve dived in the arch and the blue hole here. In my view as a divemaster, the deadly element is that the blue is hazy in the hole. You won’t even notice the mesmerising embrace of the big deep blue until it’s too late. I saw it happening to another diver. Careful…
I discovered that I have a fear of murky water, when I jumped into a very green river, with a group of friends, and suffered an embarrassing panic attack. I can't even imagine how much more terrible that feeling would be, in pitch black water, way below the ocean's surface!
I've never had a panic attack that I felt was embarrassing. If you were lucid enough to realize you were panicking, it wasn't a panic attack. You were just panicking.
@@YFZriderdude15no? not everyone experiences panic attacks the same way? I've very much had panic attacks where I was still coherent. I can feel when one is about to happen as well
Yuri’s video is one hell of a disturbing watch. Especially since you see his desperation and hear his breaths as he sinks. The first time i watched it it gave me nightmares
Underwater photographer here. The cap Yuri puts on his camera is a colour filter that helps offset the intense blue of underwater shots. The warmth of his filter is usually only for very deep filming - suggesting he always intended to go deep.
The "backside" of the Anacapa Islands are very similar in topology to this (not the same geology though). They sit right on the edge of the continental shelf, so the inland side is really shallow and great for snorkeling and recreational scuba. The backside of the island falls off to over 1000 ft almost vertically. My dad regularly worked as part of Bob Ballard's team and they would test ROVs out there because you could get 2000 ft of water under your hull a little over an hour from dock.
I saw Yuri's footage a couple of years ago. At that time it really shocked me. I didn't want to see it again. But this time your explanation helped me understand what was really going on. The fact that he had nitrogen narcosis let me realize why he kept descending. What a nightmare. Thank you Sean @Scary Interesting ⭐
I went snorkeling once in a lagoon in Hawaii. It was the most amazing experience I ever had, swimming in a marine wonderland full of huge tropical fish and turtles. That's as deep as I would ever want to go, thank you very much.
yuri's mini panic screams at the bottom are horrible. makes you wish you could've helped him. it happened so quickly. it seems weird that he didn't realize to take his weights off, but nitrogen narcosis is pretty powerful. heard its similar feeling to nitrous oxide. I could definitely see someone just forgetting what's happening and loosing their mouthpiece. id rather fish, snorkel and swim than dive anyway. The ocean is scary as hell, especially at night.
Great video! The really dangerous thing about this site is the outlet into the open ocean. It's nearly suicidal on a single tank of air (it can be done but you should likely die if you try). Further, I think a lot of the deaths are people who get disoriented and swim towards to deep passage out thinking it's the way up. Because there is light on the otherside of the swim through. Yuri was probably narced. He was too deep. He only attempted to inflate his BCD once he was already out of gas (which he sucked through fast because he was so deep ofc). Its why he dies right after. I could be wrong but I don't think he attempted to blow his vest until he literally was out of gas. He was choking well before that. The depth and weight is not a factor if you still have air in reserves. He also kept not eye on his computer until it was too late. By the time he was looking at his computer he should have ripped his weights, attempted to blow his vest and, if failed, ditch his entire vest and tank and swim for the surface. If he still had any air in his lungs he absolutely could have made a punt for the surface on a controlled exhale. Situational awareness is everything diving. And this is one of the most situational awareness necessary dives you can do recreationally. Rip Yuri - I hope your footage has saved many lives.
@ppo2424 it's unlikely he was fully saturated, but either way, a self rescue controlled exhale at this point is very likely fatal. It's absolutely not impossible though. Crazier things have happened. It's the diving equivalent of baling out of your plane. Pilots are taught to avoid doing it at all costs but they are still taught.
@ppo2424 Regardless of how dangerous it would be - the alternative is drowning. Your line of thinking is backward - in advanced diving, you work towards self rescue any way possible until you actually die. What else is there to do? Not every man who escaped USS Tang was washed off her tower or used a momson lung. Couple of those dudes did the slow exhale from near depth (she rests now at 175ft). There is a reason PADI and NAUI teach this method to beginner divers as a last ditch. If the alternative is drowning you do what you must because flipping a coin is better than 100% drowning at depth. For the love of God don't go attempting tests of this from the bottom of the Eygptian Hole. The original point of my comment is poor Yuri clearly had some attention deficit to some critical dive awareness items. Possibly due to narcosis. Danger is generally a function of how complicated a dive is and therefore how much the diver must manage to stay safe and on task. This dive seems, without having actually been there myself, to be easy enough it can be recreationally done but complicated enough to often overwhelm headstrong divers who push the limits. It's a bad combo that
This is a good video it shows how dangerous the blue hole is. I was at diving the blue in 2010 it was a great dive and awesome to see but the tour guides did not make it clear how dangerous it is or how many people had died there. Only a few month later i found out how dangerous it is.
Seeing stuff like this makes me thankful I had such a thorough dive instructor. Initially I wondered if there wasn't something special happening causing gear to malfunction in these holes (water density changing suddenly or something). Turns out its all just human error caused by lack of experience and preparedness. Always keep an eye on your depth as you descend.. you could be in a downward current and no realize how quickly you're falling.
I think I have all the phobias. Fear of heights, bodies of water, airplanes, tight spaces, spiders, elevators, tall buildings. I'm like that guy from "What about Bob" but hopefully less annoying
The video is terrifying and shows how quickly even a well trained diver can find themselves in big trouble, he sank deeper than most apartment buildings in the time it takes to brew a cup of coffee. In a way it's an important cautionary tale no unlike the corpses on Mt Everest, a reminder for the divers who've seen it to turn back/not dive in places/at times when it could otherwise have led to their demise
The periodic squeaking while Yuri descends is likely him equalizing pressure on his ear drums. Depending on the diver's physiology, this can happen naturally with breathing or by holding your nose and 'blowing' out it, forcing air into your ears. I have to do this manually while diving and it makes the same sound on camera.
To anyone wondering, that wheezing sound is just his regulator squeaking. They do that sometimes. He wasn't struggling or panicking or wheezing until he looked at his gauge and saw how deep he was. When you're in deep water like that, you can't tell how fast you're sinking at all. It can feel like you're sitting still, but you could be plummeting. Always keep track of your depth.
was he suffering from Nitrogen narcosis is that why he failed to monitor his depth gauge and just kept diving? I mean at that depth on normal air.
Maybe deep dives necessitate heads-up display tech including warnings. Hell, it being 2023, you could even program a tiny computer with your weight, gear, gas, BCD specs etc and have it automatically alert and/or respond at certain limits.
I was wondering about the squeaky sound. Thank you.
Thank you, but damn did that definitely adding to my anxiety….😳🫣😵💫
As an ER/ICU/Trauma Nurse, the deeper Yuri went, the more pressure is exuded on the Lung tissue, bronchitis, bronchi, Aveoli. etc. I could hear the expiration wheezing....which is BAD for anyone, getting worse and worse.
So many "expert" divers have all the expensive dive equipment, yet know NOTHING on how to use it properly, nor do they understand what the parameters are of each piece of equipment. They think owning all the fancy equipment will automatically protect them from the consequences of them NOT knowing how to utilize equipment properly.
And they do not have a basic understanding of the human body and why Nitrogen/Oxygen mixture ratios are so important, and at what depth different ratios should be utilized.
Too many divers are clueless on how water temperature affects the way each piece of equipment works in conjunction with the other elements of the dive.
It is sad that too many fatalities occur because of divers lacking the knowledge & patience to be an effective diver, whether it be a personal or professional dive event.
How sad. Such a waste of valuable human lives.😢❤🎉❤
The moment the camera shifts from Yuri’s struggle to suddenly being on the surface is one of the eeriest things I have ever seen.
Yeah, I've seen Yuri's footage several times before but not once have the videos ever showed that part. Absolutely chilling.
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. And terrorists (puppets of the Antichrist) who misinterpret verses, out of ignorance and political motivations, and take them out of historical context (just like radical atheists do by the way), don't help either. Thank you very much for your time.
Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them).
Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI).
Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy.
Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful.
Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI).
Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad).
Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning!
Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures.
Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement.
It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them.
(19-22 / Translated by Muhammad Asad)..
Salam (Peace) --------
Yeah I remember my dad took a lot of videos on camcorders like this in the early 2000s and a lot of his footage looked like this too, one clip just cuts off before playing a totally unrelated clip. In Yuri’s situation the glitched out tape just makes the whole video and situation a thousand times scarier imo
Aaand that was the freakiest thing I've ever heard 12:08
I almost died here.
I followed the descent through the tunnel called The Bells down to the arch (6:57 on the right). It was my 4th real dive, so I was very inexperienced. I followed the dive master and saw him disappearing into the arch. After I made it through the arch myself, I looked around and didn't see the dive master. I didn't have a proper diving computer and the mechanical gauge I had malfunctioned and got stuck at around 11 meters.
I didn't know that the arch is already on the verge of 30 meters (max depth of dive), so I assumed that dive master descended further and I can't see him, because of the cliff edge, so I proceeded. A few moments later I felt a strong tug on my fin and turned around. I saw the dive master vigorously showing ascend signs to me. It turned out that instead descending he swam sideways (just like he should have actually) and out of sight. He later showed me his dive computer. It registered a depth of 38 meters. It means that I was another 1.5-2 meters deeper than that. Had I continued my descent for another few seconds, I would have experienced severe confusion due to nitrogen narcosis and sank uncontrollably all the way to the bottom, because of compressed buoyancy control vest.
I would have ended up exactly like Yuri.
Thank you for sharing and glad that you are alive!
That's scary
under which diving organization did you complete the course?
Not worth going bro
That's probably one of the most dangerous human instincts in situations like this: when we suddenly lose track of the people we're around, we frantically start searching for them without first assessing our own situation. Sometimes being a pack animal fucking sucks. Happy to hear that your dive master pulled you right back up, I would've 100% made the same mistake as you.
That dive video is pure, unfiltered nightmare fuel. It's genuinely chilling how it all goes wrong so fast.
His descendant to 265 ft only took 3 min
Disasters take seconds, but its rarely one single thing that does it. He went alone and he descended beyond his equipment capabilities, and I dont imagine he had a real plan for a safe descend or ascent.
It went wrong about 2 minutes beforehand. It seems to have only taken moments, because by the time he realised how deep he was and tried to correct, it was already too late.
Then he panicks, and he dies.
He would have known that in dangerous situations underwater, panic is what guarantees your death. But nitrogen narcosis has been described as akin to being drunk. And at that point you don't always have a choice.
I want to go scooba diving, but it's genuinely terrifying.
Idk, always a helium mix for me in case of accidental depth. Give no chance of narcosis. Pressure alarms if possible.
Full laminated checklist that I'm not touching the water without.
So many failsafes. And even then it might not be enough.
@@musickat344 oh 100% sometimes it's not in your control! If I were always in control of my emotions it would be exhausting, and also WAY easier to get by.
Cave diving is fucking terrifying. And sometimes you just die
Diving when it’s dark like that - it’s easy to descend without having any idea how deep you are. And if you get narcosis, you lose your consciousness and it’s all over
The final moments of the footage are terrifying. The sheer panic the moment he checks his depth gauge, the silt being kicked up from him struggling to ascend. My heart was pounding. RIP Yuri.
Soon as he saw his depth meter he did try to inflate his buoyancy device.
@TH-camReviewsAndTutorials No way he intended to go that deep. He was veey clearly overweighted significantly with how fast he had descended and how much he was struggling at that depth. There is also no reason his BCD shouldn't have worked unless he was overweighted
@TH-camReviewsAndTutorialsis that something that fills with air and pulls you to the top?
I don’t feel bad for any of these divers.
@TH-camReviewsAndTutorials It looked like to me he was.. well panic might be a bit of a strong word but he sure as hell seemed to relaize things weren't OK. However I have the impression from watching the video and the context surrounding this dive that it wasn't so much the depth itself, but the speed at which he had achieved it.
He realized he descended too quickly, so he used the buoyancy device to slow his descent, but to no avail. Also the thing about the airmix not being appropriate at that depth seemed to be a cause for concern.
In a way it made me think of another video I watched earlier today about this military dude who died in an instant in a cave dive in the US somewhere.
I went diving in the blue hole in 2009 and it was really scary to go into the sea after looking at the graves that were done to the cliff side, knowing that for so many that has been their last place, and they have taken their last breath in that spot. Our diver coach was extremely strict about certain rules and had us all swim in a swarm of 10 and no one was allowed to go further then 2 meters from his/hers dive buddy. we dove to about 30 meters next to the walls, went around and came back up. it was really a different dive that day
You had a good instructor. You did not become a sacrifice like that.
In a swarm of ten divers its easy to lose one or two. Everyone should have their own buddy to look after.
*further than, not then …
@@alexvsergeev He mentions immediately after that they all had dive buddies. The instructor probably just put together 5 pairs of people per group.
It’s worth noting that Tarek said Yuri asked him about diving the blue hole, but Tarek refused and to take him without actual trimix training. I think it was Yuri’s last day or second to last day of his trip, so he didn’t want to wait and do the training. He did this against Tarek’s advice. It’s yet another really sad tale of an experienced SCUBA diver getting overconfident. This is always a rough video to watch, particularly for someone like me who has a fear of not being able to breathe. Hearing him struggle to breathe gives me so much anxiety.
Yes! I was going to make the same comment. I watched dive talk's video about Yuri and he refused to do the proper training because he was in a time crunch. The whole situation could have been avoided with even a little patience and training
why do did he keep going past 40 meters with normal air? Was that always the plan or did he push it a little too far then get Nitrogen narcosis and then continue diving down?
@@MusMasi the 'gravity' in blue holes is very off and he didn't realise how fast he was dropping. He was sinking twice as fast as he thought.
His biggest mistake was his impatience, which ended him before he even got into the water.
It's so weird when they say someone with 400 dives is very experienced. I had somewhere around 8,000 in my late twenties with cave, trimix, wreck penetration, and lots of other training and experience. I was still novice level compared to the serious cave divers I knew.
Lol, every human being who has ever lived would be afraid of not being able to breathe. There's literally nothing special or unique about you and your "phobia".
I watch these diving videos to reinforce to me that I'm a landlubber, through and through.
Yeaaaah, that shit's too vast.
😂😂
Wimp.
@@EntryLevelLuxury wimp
@@niledemitri3079 Feel like a big boy now?
I get another reason why blue holes are so dangerous - it’s incredibly disorientating: the sudden change in light to darkness, and aside from hugging a wall, you can’t tell which way goes where, especially if you’re becoming affected due to the pressure, nitrogen narcosis, etc.
Tarek is a hero. Helping people recover their loved ones is not an easy job. I've seen divers do it and struggle with PTSS after the operation. It is really hard to find people in a place where they took their last breath, where their heart stopped beating and where the last contractions of their muscles stopped.
When people die, their loved ones want to have the body, so they can lay them to rest for their closure. People like Tarek help the family give that closure. And that is amazing.

Even tho Yuri’s case has been covered many times, I appreciate that you’ve actually explained what’s happening, how he doesn’t have the right oxygen, him struggling to breathe, his dive computer, him struggling to move around at the bottom, the buoyancy device sound, the panicked moving around. So many folk have included parts of his footage and never explained what’s happening, so I really appreciate the way you’ve covered Yuri’s case and taken the time to explain everything that’s happening from start to finish.
This is the first time I ever heard of what happened with Yuri and thanks to Scary Interesting posting it.
I wish he explained Yuri's idiotness
@@royalroyal2210 Yeh "idiotness" is not a word.
How was the diver able to recover his body, even though he couldn't even bring himself up?
@@ryzezee8543 My guess is Yuri would have been able to swim out himself if he had the right oxygen mixture and buoyancy device rated for that depth. The other diver was prepared to go to that depth and recover a body so he had the proper equipment to do so.
The arch is a big reason why the hole is so dangerous. It provides a false feeling that it is the entrance to the top of the hole because of the sunlight shining through the arch. When you have nitrogen narcosis and you are panicked, you swim for daylight. That arch has killed many ppl
😊
I’m a commercial diver and have probably close to 500 working dives that being said one of the primary causes of uncontrollable descent or ascent is the reduction/increase of buoyancy as the ambient pressure increases/decreases thus compressing/expanding the air bladders in you BC or air stored in a dry suit . As you get deeper it compresses more thus increasing your decent. In a panic a person may inflate them thus creating the reverse effect. It’s exceptionally more dangerous using lift bags that are holding up 100s or 1000s of lbs of equipment for construction. They can drag a diver down or shoot to the surface, flip then drop the equipment back on the diver. The ocean wants to kill you, never forget that.
That's why it's important to sort out buoyancy and weights on the surface. The less air you need to maintain neutral buoyancy, the less pronounced this effect is. They teach this in open water dive training, but I see so many people neglect this on their first dive of the holiday.
What's the alternative to inflating your BCD in such a situation? Ditch weights? And why does it create the reverse effect? I'm having a hard time understanding that part.
@@minimushrom inflating your BCD is the best option but you have to be wary for the reverse effect: you inflate your BCD, you start to ascend, the ambient pressure around you decreases so your BCD will expand in volume, and increase your buoyancy, making you rise even faster, decreasing pressure faster, increasing the volume of your BCD even more, and so on.
So when you inflate your BCD, make sure you maintain a controlled rate of ascend, and deflate your BCD as you go up to maintain control.
Ditching weights is a last ditch resort. Unlike deflating a BCD, you cannot regain weight once you’ve shed it. Ditching weights will usually put you in an uncontrolled ascend. Beats drowning, but will give you the bends if you come up from an appreciable depth.
@@minimushrom Over inflating in a panic. I realize I'm in an uncontrolled decent, I hammer my inflator valve in my drysuit, I flip upside down as the air collects in my legs and feet, then get drug to the surface like a ballon lol. Being upside down of course complicates things. With a Dive hat if the neoprene on your neck damn is old and worn out the hat can fill with water even further complicating things. I've seen more than once from the surface little boots come bobbing out of the water with a diver on the other end.
The added risk of cutting weight in a panic on descent and then your overinflated BC or drysuit takes you to the surface as buoyance drastically increases immediately. As you ascend the air expands making you progressively more and more buoyant also making it more difficult to vent out.
I used a drysuit as an example but same concept with BC with exception to air collecting in your feet/legs. There really isn't an alternative other than just being cognizant of your buoyancy and not going into a panic. Even fairly small issues can turn into big ones if someone is losing their shit down there.
@@deepblue1846 Thanks for explaining, that makes complete sense. I had a situation once, where we swam rather quickly to the diving site and instantly went down and about 10 meters deep, where I noticed my regulator is not giving me enough air for my quicker breathing. It felt like I was suffocating. My first thought was "UP!", and I was about to inflate and blow bubbles, but then I realized that I'm panicking and acting like an idiot, so I tried to learn from this instead of going up in a hurry. I took two very slow, very deep breaths and it was really interesting, to feel the panic dissipate in seconds. That was such a valuable lesson for my third dive. I will always remember how I was able to stay in control of my brain.
Fun fact- that lens cover that was added at the start of the dive video was a red filter. Divers add them to their cameras during dives because red is the first color to be absorbed by the water at depth.
Was hoping someone would mention this, I've wondered for a while if the guy who runs this channel is a diver, that makes me think he probably isn't. He's a good storyteller and the channel is great either way, had just been on the back of my mind for a while.
@your problem there’s no way he didn’t “know” that being a certified diver, something else definitely went wrong. Could be as simple as narcosis at that depth, but it sounds like he was overweighted from the start. So he sank quickly and the issues just compounded from there.
Why is there always a "fun fact" guy on every vid? It's cheesey and you come across as a know it all.
@@garstrum4401 what video did you watch, apparently the same one as all the other commentors, one that didn't mention the part where his equipment failed maybe. The inflation of his safety vest, was his ticket back to the surface, it failed to inflate. Can you imagine. Do you dive? I've certainly never had an inflation vest failure. Never considered it. But I'm now looking online for compartmentalized inflation vests...
@@PeterPablo-fq2ps I do dive, but you can hear him inflating after he’s already hit the bottom? Plus I feel like if he was just sinking and bc not working he could’ve just ditched weights (and/or the camera, not sure what dive video cameras looked like in 2000 but I imagine they were quite a bit bulkier and heavier than todays).
Idk I don’t recall the video saying equipment failure but agree it’s certainly a possibility.
I’ve dived 60m with air, it was a mistake and I was young and too keen to push boundaries, it never happened again. It scared me so much that I still have nightmares, I hadn’t planned stops for that depth and I was suffering from NN, I don’t know how I lived or even that I didn’t suffer. I was able to make it back to the surface safely. This kind of thing happens easily if you are allowed to dive alone or split from the group.
You can dive to 60m on air that is the absolute maximum recommended limit for various reasons. You can also do no deco dive to that depth,just. The mistake was doing it without experience and not taking the right training
No deco stops when diving to 60m with air?? Your NDL at that depth is like 2 minutes, what are you talking about?

I like that you narrarate these videos in a respectful manner, not playing it up with a scary tone of voice like some other youtubers. This is tragic, and you treat it as such. Thank you❤
I'm a certified PADI OW diver with over 100 dives. In the course this case & others were explained, like the deep dive to the submarine in Australia.
Part of the course is the instructors going over deaths to sober us and be aware of the dangers to an otherwise very Zen and easy "sport" to do.
Yuri did quite a few things wrong, first by being overweighted, then leaving his buddy.
I dove with many divers that love having extra weights, not want to float down slowly, nor practice proper BCD buoyancy protocols.
A semi-argument I had with one fellow tourist in Cozumel, was that he wouldn't hesitate to drop his weights to float back up, even though I mentioned that when you panic, the very last thing divers do is ditch their weights. They overinflate then burst their BCDs.
Well, we weren't diving off the wall and the local guides let the tourists do what they want if they flash their PADI cards, so... Cozumel reefs are 5m-12m range with wall at 25m. You want to stay far away from the wall. Not much can go wrong at lower depths if you have some experience.
Cozumel reef & drift dives are an excellent dive choice for beginners and extremely safe. Just don't do any deep dives until you master your BCD, maybe after 20-ish ocean dives.
Personally I don't even like deep dives, as you see nothing. Between 5m & 12m visibility is excellent and lots of life / corals to gawk at, plus, your air tank lasts twice as long.
Yeah right, that dude is clearly killing divers by leaving them lost in the hole.
If you know what you’re doing there’s no reason to descend slowly. It’s usually good to get to the bottom as fast as possible when drift diving or wreck diving to escape the current. Making a slow ascent is the important part
@@chulo1996 Drift diving I agree, I don't do those, unless there's a buoy rope I can use.
I need to equalize my sinuses at 5m, so I take my time, maybe 15s. Others like hitting the bottom right off the boat.
I dont get it, there’s nothing really down there to look at.
@@rileyp1419 It's a "cheating death" mentality. I'm a deep cave diver and that depth is normal, but you are correct that it's often just a hole in the rock and certainly not something worth risking one's life.

People care about their own feelings over others. They will scream and cry that others are cowards who don't care about the dead's dignity and that a cultural funeral (whatever is important to their religion, or just having a body to look at) will let the dead 'rest' and comfort the survivor. To me, it is selfish and self-indulgent but I am not mad with grief.
I “found” some “footage” of you playing RuneScape and I was proud of you because I knew that you’d finally quit being a noob.
I'm going to guess that the one main issue that all of them suffered from was... not checking their instruments. When you're deep underwater, you can barely tell when you're moving. Especially when it's dark. This is a big huge hole with no clear landmarks, visual cues, or anything if you're not right beside the wall. Most popular leisure/tourist dive spots have lots of things to see, so you don't have to constantly look at your gauges. This is a deep hole with not much else.
The thing about BCDs is that you have to CONSTANTLY check and regulate the buoyancy. Because of they way they work, the air compresses as water pressure increases - which makes the BCD less buoyant. In short, the deeper you go, the faster you sink (unless you're regularly checking your gauges and adjusting the BCD).
I'm guessing most people didn't realize how fast they were sinking, thinking they were just taking a slow leisurely dive until the ground came up at them and they realize they're suddenly at 80m+. (Typical PADI open water certification is only good to 18m)
The same issue comes up when ascending, too. BCDs get MORE buoyant as you ascend and water pressure decreases... which means divers will rocket up to the surface unless they check their gauges and control the BCD. Now they're going to deal with decompression sickness.

I almost skipped ahead when I realized you were going to talk about Yuri, since I have heard his story many times. I'm glad I didn't because I have never seen the footage the way you showed it,and your narration was perfect. This was the first time I actually felt anxious while hearing about his story and watching the video. I caught myself holding my breath and wishing he would stop,turn around, and return to the surface.
Well done, as always!
It was stupid of me to watch the raw footage one day after getting Open Water certified.😊
@@2KOOLURATOOLGaming actually it was probably a good idea, to learn from the mistakes of others. Be safe.
@@2KOOLURATOOLGaming nothing wrong with staying in your lane and taking things slow, the ocean is unforgiving of mistakes.
@@2KOOLURATOOLGaming nah, Yuri was the stupid one
I prefer this narration style, photos, diagrams, footage
I dont wanna watch a guy just sat talking at the camera like how some do it
it's so crazy that there were other divers at a lower depth than him just moments before it was all too late..
Why is that crazy ?
I'm guessing that you don't know anything about diving. Divers going deeper than about 120 ft. have to breath a special mix of air (tri mix) .
This dumbass died because he was using regular air. He's a diving instructor for Christ sake. He teaches this to people on the first day of dive class.
How deep a person dives is dependent upon their gas mix and equipment. There is no situation in which anybody would dive a new spot without constantly checking their depth monitor. Guy's an idiot, and it's a good thing he is no longer a diving instructor.
It makes it more tragic! I doubt that they survived..
@@GigiRockEMOwhat? Just because they were deeper than him does not in any way imply they died.
@@GigiRockEMOthey had correct tanks for that level
I'm Egyptian and I've been to the blue hole several times, but only for snorkelling. I remember the first time staring down the abyss and it was just hauntingly beautiful. The first time I went there I wasn't aware at all of its morbid history, I just innocently snorkelled around the edges and enjoyed the reef and the fish. In fact, dahab and the blue hole are a very popular local vacation spot and it's surprising how almost no one knows how truly dangerous it is. When I found out I was horrified and it made my second visit there much more somber but still hauntingly beautiful.
Let's not get into the non existent safety regulations, basically anyone can get in the water and swim around the blue hole with no supervision. So I'm not surprised at all that there are no official records of the dives.
But still it's my favorite spot to swim around in Egypt and I wouldn't miss an opportunity to visit this enchanting site again! :)

@@chrisxsoo Nitrogen narcosis takes time at depth (below 30 meters) to kick in. He was fucking up right away, can't blame nitrogen narcosis here.
Hi, advanced open water scuba diver here! So, there were a couple of things I noticed just because I have the context of training.
1) I don't think he had a diving buddy. One of my number one rules is to always dive with a buddy! Your chances of survival drastically increase with a buddy, and there's just no sign of anyone else with him. You would usually hear the other person breathing as well.
2) Regulators just have a squeaking noise that they make sometimes. It happens when you breathe in. His breathing didn't become panicked until he realized how deep he was after looking at his computer.
3) I am amazed that he did not look at his computer during his descent without a guide rope. Guide ropes are used so that you can ease yourself up or down at a measured pace. While ascending, you have to look at your computer to make sure that you aren't going up too fast (decompression sickness), but almost equally as important, you have to look at your computer while you descend - especially when you're diving in a place deeper than your maximum allowable depth, so you don't go too deep. That he NEVER checked his computer until he hit a ledge baffles me. I think with normal air and an advanced open water scuba diving cert, you can only go a maximum depth of 100 ft, which is more or less out of nitrogen narcosis range (it varies from person to person), and you need special air mixing certifications to get the air mixtures that prevent nitrogen narcosis and allow you to dive deeper.
Anyway, just some observations. It is truly tragic to lose one of our own, but watching these reminds me of all of my training and safety protocols I learned. They're always written in blood, it seems.
The procedures in scuba diving are indeed written in blood, and once in a while someone will come along and remind us of it. It's kind of the same thing with the high prevalence of open water instructors who die in beginner caves. They go into the caves with no training, without the right equipment, but all the hubris in the world. And die.
Just a couple of small corrections on your video:
- @06:50 - the part of the dive map labelled "arch" isn't the entrance to the famous arch on the inside of the blue hole (at around 52m or so on the inside wall facing out towards the ocean). It's a separate feature from the blue hole altogether called the bells further down the coast. It's a chimney like feature with a more or less vertical drop from sea level at the surface which goes straight down and exits around 30-40m facing out into the blue (the ocean). The wall itself that it and the blue hole are situated within go down to depth of I believe around 800m. Once you pop out of the bells, a common diving route is to then do a gradual swimming ascent along the wall until you reach a shallow saddle at about 6m depth which then takes you into the blue hole itself.
- The other point to mention was that it's not so much the case that people choose to morbidly go and see the grave stones - it's simply that to do the bells to blue hole dive, you have to walk past them to get to the bells to start your dive. It's a very sobering reminder to not let ego overtake skill, training, equipment and experience.
- @10:37 - that thing he's attaching is a red lens filter. They're used in dive photography for colour correction as red light is filtered out by absorption as divers descend. Without them, photos look flat and very blue or green so it effectively restores some of the natural colours that are present underwater.
- final point - another reason for the blue hole being so deadly is because of the appeal of the arch. You can see it pretty clearly from above at 40m (the limit for recreational scuba diving) and water distorts perceptions of distance. Lots of divers have gotten into trouble/died because of this factor as they assume that the top of the arch closer than it actually is and that they can make it down there with single cylinders with air (21% O2). Unfortunately, the tunnel the arch opens into requires that divers descend further to exit on the other side of the wall and once you're in there, you're committed. This is where the problem lies as for most people, this route at this depth simply won't leave enough gas to make the ascent and the necessary decompression stops to avoid decompression sickness (aka the bends). Add nitrogen narcosis impairing decision making, increased air consumption at depth, likely an elevated breathing rate due to hard work and adrenaline/stress and depending on how deep divers go, the risk of convulsions brought about by oxygen toxicity from breathing normal air at a high partial pressure...this is what makes the blue hole so deadly. If you dive the blue hole site, it's easy to see the light hitting the arch and think "I could just go that little bit further". Without the right training certifications, buddy/dive team and equipment, it's just not worth the risk. I should also say, for all its reputation, it's actually a pretty boring dive. The same goes for the Belize Blue Hole as someone who has been fortunate enough to have dived both.
Aside from that, I just want to say that I'm absolutely loving this channel!
That's some really awesome and useful information. I always look for comments from people who genuinely know what they're talking about. Thank you for your comment. Stay safe on your diving trips.
Thanks for the info! Honestly, they do seem rather boring lbs
Excellent info.....
Thanks for the info.
Much appreciated.
What's not a boring dive? Other than cave diving of course, that looks terrifying.
It is highly probable that Yuri knew how dire his situation was. Especially in the last 1 to 2 minutes of his life. He seemed to be highly panicked and it was also reported that he was also trying to shed all of his equipment in an attempt to surface. Terrifying
Highly probable that a dive instructor would know a few things
What a disgraceful username.
@@joroc, he was an open water diving instructor which does not in any way qualify him for this type of dive. Totally different skillset. He most likely didn't understand his situation until he was WAY past the point of no return. In technical diving it is very easy to "paint yourself into a corner" if you don't know what you don't know. A lot of technical diving training covers how to calculate and plan the dive so you don't end up in that kind of "no way out" situation. Yuri was beyond the point of no return for a long time. He finally realized it in the final minutes, but he was already a dead man much earlier in the dive.
Terrifying...
And Stupid
@@CL-gq3no IF he was an OWD instructor, he should have known better. As in a lot better, regardless. Believe me. You don't do these kind of dives on air. Full stop. It's not rocket science. The information is out there. The skills and knowledge are taught, and reasons why explained. I expect far better from an OWD instructor, than killing themselves. Watching your gauges, is critical, especially when you cannot see the bottom, because judging speed while descending is very deceptive, even if you are near a wall.
I'll keep myself on land where I belong thank you very much for reinforcing that very well with this video!
Edit: take note that this advice is 30 years old. As some replies point out the regulations are nowhere close to how they were when I was diving. So just make sure you consult expert and you should be fine.
Original comment : tip from an old diver. If you do not have any certification for scuba diving. Do not under any circumstances let yourself be convinced by a local dive shop that they'll let you go diving with a quick few lessons. You should only dive if you were certified by a recognized organization like PADI or whatever smaller ones there are. But never, EVER, accept training that is done on the spot before a dive. Thats a recipe for disaster.
Also, I like what one of my first instructors told me about diving. He said unlike other sports. This sport is a sport which you do not do to get in shape. Its a sport that you need to be in shape in order to be able to do it. In the best of situations it doesn't require that much effort. But if a quick current takes you or something bad happens. How healthy and fit you are will be a huge determining factor on whether you survive the problem or it takes you down.
What the hell was Yuri doing? For those who dont have diving experience. Doing a descent in open water without the use of a guide rope requires special training. Its really hard to guage how fast you are going down. The fact the first time he looked at his depth guage was when he was near the floor of whatever ledge he landed on seems insane to me.
I hear you pro tip. I have done two "adventure dives" where i was alone with a diver instructor and have not been formally trained myself. The first time was with my brothers friend who was a military diver for most of his life. He was excellent, kept me in 10 meters of water and was attending me and checking my gear, air reserves and communication regularly. It was an amazing experience. My intention after this dive was to get training. it never happened. I went on a second dive with an instructor i did not know. About half way through the dive we started a descent that i was not told about and was very uncomfortable with, I couldn't see the bottom and had no visual of where he was taking me.. He didn't notice for a while that i was no longer following him. We ended that trip and i haven't been diving since that event.
@@mistertubby
Wow, I have to say kudos for keeping calm in that second dive. That's a typical scenario where someone with no training might panic and do something dangerous.
It boggles the mind that people who call themselves diving instructors would be comfortable brining someone with no certification on a dive.
My basic scuba diving training took place over the course of 6 or 8 weeks, with a full weekend certification trip to some horribly cold and muddy lake.
Each session something like 5 or 6 hours. Half was theory and the other half was practice in the huge pool.
Definitely made me appreciate the potential dangers. One guy actually quit the class after panicking in some exercises in the pool where we had to remove & purge your mask and practice breathing without your mask on. If at the very least the instructor didn't show you how to do these types of things, he basically rolled the dice with your life.
If you ever do want to try diving again, look up some classes. You'll have all the knowledge, skills and proper confidence needed to safely have fun.
A buoy with a guide rope attached would be smart there that’s definitely scary. I’m pretty fit but because I am I sink like a rock! With equipment even worse! At 80m idk if I can come out of that alive 💀
@@mario6279 You would need less weights on your belt. But every human being has a slightly positive buoyancy . Which is why divers will wear weights to help sink. But as you go down and your wetsuit and body compress you become less buoyant. Which is also why divers wear flotation vests. Its linked to your air tank, and you fill it or empty it in order to keep yourself as close to neutral buoyancy as possible. A bit like a submarine does with its ballast tanks.
I think I would always use a guide rope. In fact, after watching this, I win use a guide rope in my local swimming pool
I had never seen Yuri's video before, god, that made my anxiety shoot through the roof.
I've known about this case for years, but watched it for the first time making this video. Nerve-wracking, to say the least!

@@turkeydoctor5546no! Sorry you’re on your own and I see a shark in the distance; “bye”!
That's a tough video, but a well narrated example of how bad things get quickly. It's a shame it cost that diver their life.
watching him move around knowing it was too late was too much for me. What an awful way to die
When I was 13, I was diving King Cruiser in Phuket (top of the wreck is about 20m and bottom is 32m) and went to the seafloor to swim under the wreck. The experience was incredible, tens of thousands of fish schooling around the wreck and feeding on the coral ecosystem that grows onto sunken ships. At the time, I was PADI certified to 60ft (18m) and the dive master told everyone to stay at the top of the wreck, except for a few advanced open water divers. I was getting my advanced open water cert the next year, and I have been swimming my whole life so I went straight to the bottom and started swimming upside down to view the underside of the wreck.
When I tell you that pressure changes quick, that is no joke. My BCD was barely able to handle neutral buoyancy with my weight belt, and my tank hit the seafloor. Luckily 32m isn't deep enough for oxygen toxicity, but it was a strange feeling to have to swim directly up to get off the bottom. I would definitely do it again because the views were spectacular and I love wreck diving (not the 2m eels though...), but I HIGHLY RECOMMEND never going below 30m without equipment set up specifically for that purpose, especially for new divers. The feeling of being sucked down by pressure is so foreign to creatures that are normally pulled down by gravity that it is easy to panic or lapse judgement.
If in doubt, always establish neutral buoyancy each time you descend, because the BCD buoyancy limit can sneak up on you. And please, if you dive a blue hole stay in view of the walls to gauge rate of descent. Nature does not care, it does not think. Only you can plan ahead to keep yourself safe.
Jesus going an extra 12m on a dive could really mess up decompression stops. When I went diving we always did extra time if we had the air.
My parents were avid divers back in the day, and my mother lost it while diving in a blue hole (I don't know which site it was). She said she just looked into the dark depths and zoned out, and apparently starting descending way too quickly, not realizing what she was doing.
My father noticed after awhile that he couldn't see her, then saw some highlighted yellow part of her equipment way below him. He got her before she descended too far and had permanent issues, but she was sick as hell from decompression since she bobbed up past him once she snapped back into it.
I enjoy diving, but I usually try to stick to fresh water sites. The ocean isn't for me, other than short sailing and kayaking trips.
My mom (hairdresser) had been asked to come into the hospital to see a clients daughter…
She was over 90ft under when her appendix burst …
She came up as calmly as possible, still got the bends..
Had to be in a oxygen tank for weeks.. they ended up saving her life but her long blonde hair had been in salt water & then untouched for weeks as she went thru treatments in the hospital.
My mom spent days trying to comb it out.. finally, ended up having to shave some parts & gave her a an asymmetrical Bob to cover it up.
Everyone was in shock she even survived.
The closest I go swimming is at the recreational centers that has a full size olympic pool and even then, I'm still extra caution. Other than that, it's heck no for me!!
Have you ever dived in Great Lake wrecks? I remember seeing some on TV as a kid, the old wooden ones are so well preserved
Your mom should go play RuneScape. She’s such a noob.
or.. u could go reef diving with crystal clear water.. just saying
It's amazingly scary to see how quickly the dive turns from peaceful and enlightening to deadly. Prayers to all
Two things: 1 Redfilters are generally installed underwater so that there is water behind them to correct refraction. Your images will be distorted if there is a layer of air between the filter and the lens.
2 Not to be calloused but this dive did not go "wrong" underwater. It went wrong when he planned his gear configuration. From what the video stated he had too much weight on and even with a fully inflated BCD couldn't gain buoyancy. That means he was over weighted or his BCD was not rated with the lift required to correct his decent. I have seen divers dive with both of these problems for years with no issues HOWEVER cold water at depth will compress the air in your neoprene wetsuit (all air actually) and may turn you into a "dirt dart" then you will descend rapidly until you hit the dirt sometimes you can't do anything about it. Buoyancy control is something that is SO neglected in the training phase because it isn't flashy and takes a TON of time and intuition to develop.
Just bring an extra few weights or even a rock, in a bag then dump them if you want to drop suddenly but come back up.
Some people find common sense difficult.
81 meters and still falling because it's goes to 84 in the same shot. That's so tragic. He knew that he needed to have tri-mix for the type of dive that he was gonna do. It creeps me out how many divers decide to do any dive by themselves. It doesn't matter how good or bad you are at diving if you dive alone...you are alone. RIP, Yuri and all others lost in this blue hole.
But he had a buddy - only that they apparently didn't care.
@@gewinnste Some buddies do care but aren’t able to stop you if you do something unexpected or crazy.
he had a local not a professional diver and what can he do when he sees him keep diving to dangerous depths@@gewinnste
I know nothing about diving at all but I have common sense and it seems pretty obvious to never do something like this alone.
I'm curious about his kit. It seems like even with his emergency floatation device inflated, he was still negatively buoyant at 80 metres. Even if he had the correct gas mix, wouldn't he still have been stuck on this ledge unable to ascend, or worse, in open water sinking all the way to the bottom?
As a technical diver I found this video a stark reminder of how quickly things can go wrong. I get nitrogen narcosis at around 40m on air and totally confused at 50m. I cannot imagine what was going through his mind at 80m. Trying to make any sensible decisions I would venture to suggest would be impossible.
Honestly it sounds like a good reason not to do any of that. An activity that relies on intelligence to do safely, where the nature of the activity impedes intelligence, is basically a runaway chain reaction waiting to happen.
Just like people climbing to altitudes where lack of oxygen makes them irrational. There you are, in the most dangerous place you've ever been, and you've got absolutely terrible judgement as a natural consequence of the conditions there. Seems like a great reason not to go.
@@aluisious Yes it does sound rather stupid. However it is a test of your ability to focus and concentrate to maintain awareness of what is around you and where you are. I enjoy this sort of diving as it is totally distracting from everything else going on in your life. It is a total test of self discipline and awareness.

@@markb7898forcany extreme sport
Thank you for this informative video. It is great.
About the Yuri incident, there are a few remarks though, which can be better explained:
- at 10:30: " Yuri fiddles with the camera, attaches something ... to protect it from the pressure he knew he would experience "
This is a red filter and has nothing to do with pressure. Under water videotography struggles with the effect of light being absorbed by water. This begins gradually within the light spectrum starting with red, which is absorbed after only 3meters of water. To compensate for it you use red filters. You also will notice the gain in red hue after he attaches the lense.
- at 13:30:: " his buoyancy control would´ve become less and less effective as the pressure increased"
No this is not the case. The opposite is true. Buoncy in the shallows is more difficulte as the percentage difference of the pressure increases and vice verca decreases with depth. For example, diving from 0 to 10 meters is twice as much pressure (100% increase) you have to compensate for. The same 10 meters from 70m to 80m only is only a mere 14% increase in pressure you have to compensate for. The pressure for the buoncy jacket requires the same pressure as the surrounding, i.e. 8bar. A standard dive would start with 230bar. So there is no propblem with compensation.
- also at 15:11: the equipment he has is too heavy.
Yuri is an dive instructor. The notion that he is too heavy is something I would definitly not go along with. As a diver, especially with deep dives you try to be as light as possible, as it allows for less trouble with buoncy. J
- at 14:35 "regular air isn´t recommended below 40m"
Well there are dive organisations, which do not allow for more than 20m. But the fact of the matter is this. On regular air you can go to 70m before the partial pressure of oxygen becomes toxic to breath, at 1.6bar. And here is the math: 0,2bar Oxygen * (7bar (waterpressure at 70m) + 1 bar atmospheric pressure) = 1,6bar
Notwithstanding Nitrogen narcosis and decompression sickness.
What was apparent to me is this:
- why look for a dive body when you swim past him?
As I have often found, to do underwater-vidoes requires a well coordinated team. The guy with the camery sets the pace. Whenever I dove with somebody else they would not wait for the camera to be ready, or the time it took to take footage and we lost each other. It went so far that I declined to dive with anybody else or other than my wife and would not take anybode with me.
Yuri found somebody on the street. And as he was fiddling with his setup his dive-buddy is nowhere to be seen. That is bad. No team-play whatsoever. Than at
at 17:03:49 (footage) there are two other divers around him at the surface, both yellow fins
17:05:52 (footage) passing a lone diver - blue fins.
By the way, none of these other divers you see in the picture are very good. They act like seehorses. Upright and constantly kicking. An experienced diver is horizontal, hardly moves at all and fine-tunes his buoncy, mostly with his breath.
- The breathing becomes laboured and hectic - he starts gulping at the end of ever breath
at 17:07:02 you can clearly hear these gulps. First I thought it might be a problem with the equipment, so I went back to the beginning of the dive. But in the beginning the sound of his breathing is clear ond relaxed. So it is clear that Yuri was struggling, becoming ever more prominent at around 17:07:00. It is obvious that nitrogen narcosis starts to set in.
- Yuri died from Oxygen poisoning
What this video completly fails to mention is that Yuri was in the death zone. What is the death zone? It is the depth when oxygen becomes poisonous, at 1.6bar. Please refer to 3 sections above, where the math is explained.
17:03:30 dive starts slowly, divers all around - absoluty no indication of too much weight, as the Yuri is calm and descent is extremely slow
17:04:00 he descends - his descend rate is about 20m/min = (17:04:00 hrs - 17:09:00 hrs) / 93m = 5min / 93m . This is fast but still ok. With a dive so deep you have to account for decompression time, so there is no time to linger.
17:05:52 (footage) passing a lone diver - blue fins, maybe his dive-body? They pass and the other guy is not to be seen again.
At 17:06:42 shortly before he is affected by nitrogen narcosis he inflates his jacket. This is a good thing, as it demonstrates, that he his cognitive about his sourroundings, knows what is going on and reacts to it.
17:06:50 Shortly afterwards he starts gulping. The diver is clearly in distress, probably induced by nitrogen narcosis. Taking the projected descend rate of 20m/min into account he is now 60m deep. There is no clear math to it. But I can assure you that you feel the nitrogen from 50m and below. Yuri is now 60m deep and his breathing is affected by it.
17:07:00 the bottom comes into view, about 5m below. Visibility is bad at about 6m. But the bottom drops off and Yuri passes along.
His descend rat is still constant at 20m/min but he enters the oxygen death zone. Nitrogen narcosis and oxygen poisoining result in a complete loss of control.
17:08:30 - checks dive computer for the first time: 81.7m he is now well into the death zone. Movements are erratic and diver shows clear signs of distress, loosing orientation, time and cognitiv abilities.
17:08:33 - 83.7m
17:08:42 - 89.6m
17:08:49 - 91,8m.
17:09:00 he crashes into the ground. As an experienced diver would never ever do that. And mind you, no attempt to inflate Jacket - total loss of control.
17:09:03 - depth 93m??? Inflates jacket but does not go up - clear indication that not enough air was used to inflate the jacket. Stops to inflate further, as was required, while body reactions become ever more frantic. Jacket does not burst, as there is no accustic indication for that. No malfunction of the jacket.
17:10:58 - struggles while on the ground, - video breaks off.
- Technical problems with the vest - "the jacket burst due to overfill"?!?
This implies a faulty equipment, which attributed to the event. The events that transpired lead me to the conclusion that the Jacket during the dive cleary functioned flawlessly. If anything, the burst might have happened when the dead body was brought up and the decompressed air at 90m+ inflated to 10x it´s volume.
And these is the chain of events that brought me to that conclusion:
17:06:42: Yuri inflates his jacket when he passes 50m, to compensate for the compression of lungs, jacket, dive-suit. Everthing seem to be fine and he progresses the descend.
17:07:00 60m - Yuri has difficulties breathing, acts ever more erratic. No indication of using the inflateble jacket.
17:09:03 93m he inflates again, but does not ascend. He inflates for 4 sec. This might have been too short. The notion he is too deep and too haevy is wrong. A good jacket for an adult can easily compensate for 25-40kg buoncy. In the beginning, on the surface he was well balanced since the descend is very slowly. So there is no indication that he was too heavy. At 90m+ his buoncy was negativ and the 4sec of inflation was just not enough to change that. At the end it is stated that the vest has bursed due to being overfilled. I do not believe that on account of 2 factors. He does only inflate twice, past 50m (a short burst) and at 90m. The burst at 90m lasted for a mere 4 sec. That is just not enough to make it burst. And then a divemaster has a professional vest. Those vest do have a valve to compensate for overperssure. So it is not even possible to burst it. And like I said it has more than 25kg (250N) uplift capacity, some up to 45kg. That should suffice in any case.
I do not want to exclude a technical failure. But the footage indicates that the jacket was just fine. At 50m he inflates and procedes. At this point he was still lucid. Had the jacket shown any malfunction he would have reacted, which he didn´t.
The 4sec burst at 90m was just too feeble an attempt. The prior clear indications of nitrogen narcosis combined with oxygen poisoining account for the inabilaty to react properly.
From 17:08:30 on, when he checks the computer which indicates more than 80m he does nothing to stop the descend - no inflation of jacket. He goes ever further and his cognitive abilities are impared. Also, you don´t hear any burst. And it does not burst as the diver drops ever deeper, since the pressure compared to the outer pressure decreases, relatively speaking.
So NO, there is no indication that this accident was due to technical failure.
If the report is true though, that the jacket did indeed had signs of a burst upon retreaval, there is one logical explanation for it. It must have happened when they lifted up the body. Let´s say he has like 7ltr of air in his jacket, at over 90m. This would expand to over 70ltrs on the surface. I suspect the retreaved the body from the ground, brought him up and at some point the buoncy was positiv at which point they would let the body go by itself, which caused a rapid expansion of the Jacket and thereby caused the burst.
Summary:
There was no proper coodination with Yuri´s dive-buddy. They did not know each other and might have had different expectations and a different level of experience at the projected depth. Then it was an unfortunate combination of nitrogen narcosis, combined with oxygen poisoning. So, one error played into the next which led to this unfortunate, causal chain of events. It was human factor, no technical malfuction.
Your maths is wrong, the PPO2 is 1.6 at 60m not 70m and that is the recommended maximum on air.
As a diver I ask myself how that happened.
Okay, it was back in the year 2000 - but wasn't it usual to check the depth in those days?
What was his plan?
How deep wanted he to go?
I can't imagine, that a divemaster cannot control his descent and stop sinking deeper at 30 or 40m.
He would have been trying to dive the arch, which is at 60m.A DM, just qualified has little experience,they're normally young and dumb, experienced ones are worth their weight in gold.Most of the fatalities on that dive are caused by over confidence and bad practice, ie diving on a single tank, not used to strong narcosis etc.Very avoidable sadly. @@DerOetzmann
Why is he going deeper and deeper and didnt check his depth much earlier? What was his intent during the dive at all? I don't understand how you put yourself at risk that way.
Yuri’s video is equally terrifying as it is just sad. Such a simple mistake of diving down too far and being unable to ascend, I can’t imagine how scary that must have been. Unless you’ve scuba dived it’s hard to describe the feeling of depth… I’ve been a diver since 2015, the deepest dive I’ve done is down to roughly 35m and even that felt like a long way down, to the point the water becomes murkier and green, looking up you can’t make out the ripples or waves of the surface, you feel like you’re just in an open abyss. So I cannot imagine being as far down as Yuri was, entirely alone, in the dark, probably knowing you’re going to die down there, so incredibly sad.
ALSO: Sean I’m sorry if you’ve already made a video on it, but have you considered telling the story of David Shaw? His story is very interesting, there’s a documentary about it on YT called “Dave’s not coming back”, highly recommend.
David Shaw’s story was impressive!
Hello fellow diver,
a friend of mine was a military-diver in the 90s, and they experimentet with oxygen-narcosis. they went over the limit alone and then got recovered by their colleagues. he said its like getting 1-2 bottles of whiskey in your head at once, its a big freakin hammer and you basically feel nothing anymore. so on the bright side its probably save to say, that you dont feel scared when you hit 80meters. looks like he is super dizzy, not realising whats happening, doing one thing he can and then the mind just wanders off
i have reached 45meter with oxygen, by not breathing past 35m and just tipping the ground of the coean and getting back up, so i cant really verify it, but the guy stopped counting past 5.000 dives so i trust him on what he experienced
Hello ! May Allah protect and guide you to his light and happiness in this life and the hereafter, God bless, Ameen. Excuse me for giving a little presentation of Islam, because it is very misunderstood nowadays, especially on those « Antichrist's » times, where media and politics are mixed to distort history and truth. And terrorists (puppets of the Antichrist) who misinterpret verses, out of ignorance and political motivations, and take them out of historical context (just like radical atheists do by the way), don't help either. Thank you very much for your time.
Islam is an arabic word that means the Surrender to the One and Only God, our Creator, Protector, Provider, who gives us life and all that we have, we are safe and sound by his will and grace, we are His and to Him we return, and we have to thank him in this trial life by submitting to him by our free will, or later in the Day of judgment when it's too late to save our own skin. Islam was the original Religion descended to earth from heaven with Adam and Eve (peace and blessing be upon them) in the beginning of humanity. and was passed to people with the succession of the 124 000 prophets and 315 messengers of God to all nations and civilizations since, passing by Noah, Abraham, Isaac, Jacob, Ismaël, Joseph, Moses, Aaron, Joshua, David, Solomon and Jesus (Peace and blessing be upon them) during the history of mankind, the last replaces and completes the previous, until the succession of the last messenger of God fourteen centuries ago, Muhammad (Peace and blessing be upon him) to complete the noble morals of all mankind, to bring humans and jinns out of darkness into light, and to purify people's religion and belief from corruption and polytheism, and return it to purity and true monotheism, like it was in the times of the prophets (Peace and blessing be upon them).
Many Religions that we know nowadays, at their beginning were true and under Islam, initiated by one of the prophets of God, but their original teachings, history and scriptures have been corrupted over time with falsification and polytheism, or lost and replaced with false ones. That's why Islam is the only Religion accepted by God nowadays, which consists in bearing witness that there is no god besides Allah (God in Aramaic, the original language of Jesus and the Gospel), and that Muhammad is His servant and messenger, just like Jesus and Moses and others are His servants and messengers. Never a messenger of God said he was God or literally son of God, it was the people after him who changed the words of God and corrupted the Religion. God is unique and absolute, He does not need to have a family and sons or to associate anyone else with His kingdom, He can simply create whatever He wants, everything belongs to Him, and to Him everything will return. Allah said in Surah Al-Mu’minun : “God has never begotten a son, nor is there any god besides Him. Otherwise, each god would have taken away what it has created, and some of them would have gained supremacy over others. Glory be to God, far beyond what they describe. The Knower of the hidden and the manifest. He is exalted, far above what they associate. (91-92 / Translated by ITANI).
Allah means the one and only God, the God of all prophets and creatures, the creator of the universe and mankind, and the Master of the Day of judgment, where our destiny, Hell or Paradise, is decided based on our faith and deeds in this trial life, and above all, Allah's mercy.
Allah said in Surah Al-Ikhlas : In the name of God, the Gracious, the Merciful.
Say, “He is God, the One. God, the Absolute. He begets not, nor was He begotten. And there is none comparable to Him.” (1-4 / Translated by ITANI).
Allah said in Surah An-Nisa : O FOLLOWERS of the Gospel! Do not overstep the bounds [of truth] in your religious beliefs, and do not say of God anything but the truth. The Christ Jesus, son of Mary, was but God's Apostle - [the fulfilment of] His promise which He had conveyed unto Mary - and a soul created by Him. Believe, then, in God and His apostles, and do not say, "[God is] a trinity". Desist [from this assertion] for your own good. God is but One God; utterly remote is He, in His glory, from having a son: unto Him belongs all that is in the heavens and all that is on earth; and none is as worthy of trust as God. Never did the Christ feel too proud to be God's servant, nor do the angels who are near unto Him. And those who feel too proud to serve Him and glory in their arrogance [should know that on Judgment Day] He will gather them all unto Himself: (171-172 / Translated by Muhammad Asad).
Allah the Most Merciful said in Surah Ali-Imran : Behold, the only [true] religion in the sight of God is [man's] self-surrender unto Him; and those who were vouchsafed revelation aforetime took, out of mutual jealousy, to divergent views [on this point] only after knowledge [thereof] had come unto them. But as for him who denies the truth of God's messages - behold, God is swift in reckoning!
Thus, [O Prophet,] if they argue with thee, say, "I have surrendered my whole being unto God, and [so have] all who follow me!" - and ask those who have been vouchsafed revelation aforetime, as well as all unlettered people, "Have you [too] surrendered yourselves unto Him?" And if they surrender themselves unto Him, they are on the right path; but if they turn away - behold, thy duty is no more than to deliver the message: for God sees all that is in [the hearts of] His creatures.
Verily, as for those who deny the truth of God's messages, and slay the prophets against all right, and slay people who enjoin equity - announce unto them a grievous chastisement.
It is they whose works shall come to nought both in this world and in the life to come; and they shall have none to succour them.
(19-22 / Translated by Muhammad Asad)..
Salam (Peace) --------
@TheSilentpulse it's either oxygen toxicity, or nitrogen narcosis. Nitrogen narcosis hits most people slowly after approx 40mtrs. Fairly harmless if you are aware of it, and resolved by ascending to shallower depth.
Oxygen toxicity has to do with the partial pressure of oxygen due to depth, and we aim not to go deeper than 56 mtr with the normal 21% oxygen. Symptoms can be like an epileptic attack, very dangerous.
(Instructor/over 3500 dives)
Correct. Unlike some of the guess work on here.
(former military diver + supervisor/instructor 7 years and commercial diver 9 years)
I've dived the Blue Hole in Dahab. It's stunningly beautiful, but naturally dangerous. It's safe as long as you stay alert to that danger, are properly trained and follow the protocols - including keeping a close eye on your gauges, because it's otherwise impossible to judge depth there.
I have a friend who is a hardcore technical diver (tri-mix rebreather), who told me he has been to the bottom of the Blue Hole a few years ago. He saw a couple of the unrecovered bodies on the way down; nothing but skeletons in wetsuits, slightly inverted by the little bit of air left in their tanks. Haunting.
I know nothing about diving, what do you refer to as "that" danger in your comment?
@@simonforfan I believe they were mainly talking about the difficulty gauging depth. A lot of general recreational diving happens in locations where you can mentally keep track of your depth based on reference points in your surroundings, or the dive will be centered around a fixed goal at a certain depth (for example, ship wrecks are at a set depth that you'll know in advance, so if you're above it, you know you're above whatever depth it's sitting at). In those cases the main risk isn't going too deep, it's staying on top of your air and decompression stops so you don't end up with the bends.
Because the Blue Hole has lower visibility and the ocean floor is out of sight, there's no good reference point to judge your depth by. Going too deep is a risk that compounds on itself because the deeper you go the less buoyant you become, and if you aren't paying attention and don't realize you're sinking you won't realize you need to adjust your buoyancy, causing you to sink faster. If you do go too deep, staying calm and keeping a clear head is the first step in correcting it, but the inebriating effect regular air can cause at deeper depths works against that. When you panic, your breathing increases- worsening the effect- and it also makes you more likely to make additional mistakes that could endanger you further.
If you are aware that those risks exist, know that you can't rely on your senses and need to be regularly checking your gauges, you're unlikely to end up going too deep in the first place, or can catch it quickly and correct yourself before it becomes truly dangerous. You'll also just generally be better prepared for what to do in that situation because you thought about it in advance, so you'll be less likely to panic.
It's not more or less dangerous than diving any other spot with essentially no bottom. Unless you attempt to do stupid shit and dive beyond your training you'll be fine.
i only dived like 10 to 15 times, and the last time was in egypt actually vey near that exact blue hole. i got drawn away from my group by current on normal air, according to my depth gauge and friend i dropped to like 40- 50 ish meters in depth, i dont really know what i did, but i lost a weight in the process, and if it wasnt for my friend stopping me i'd have swam up to the surface. and it wasnt the darkening of the water, or my friend growing smaller that scared me, it was my changing mind state, and only a second long feeling of "this is fine, just go with it" it almost felt like when i used to work in a kitchen as a teen, and i would do whippets with nitrous when i was alone there and bored. Honestly i think it was my experience with getting high on laughing gas that helped me catch my bearing and act fast enough to survive that day.
Ah my nightmare provider, right on time!

This comment.
there's plenty of other youtubers bro
try mr ballen and thank me later also mr nightmare nightime spooks chilling scares ripshy and whispered diaries
*I'm honestly glad they didn't go on to be "professional instructors/guides" in that area.*
So many others would have lost their lives too, considering they both lost their lives that fast. Whether it was their fault or the local tank fill shops.
If they died that easily they would have just gotten others killed.
I'm very sad they lost their lives, but that doesn't mean they should have been guides/instructors for other people, many of which would be newer and less experienced and less capable than them.
I feel extremely bad for them, and far far worse for their families.
However I still feel if that happened to them they shouldn't be the heads of a tourist diving agency that takes people to the hole.
Anyone who cares about human lives should think that as well.
I know I'll get hate for this, but I don't care to be honest. If you can't keep yourself safe you absolutely can't keep a group of divers safe, not when plenty will have zero experience in the hole.
I've watched a lot of this type of content. "scary true stories" of caves, divings, etc., and yours is by far the best. I think what I love most is that you include several stories in most videos and you only report on the story and don't embellish like others do. You do a really great job and I love listening to these stories, as tragic as they may be. Thanks for the good work.
You’ve become my favorite channel to listen to at work. Your content is just chefs kiss. 😭🤙🏼
Me and my brother are somewhat experienced drivers, both with advanced open water PADI certification. My brother loves photography and I can tell you that at 10:30, what Yuri is doing is attaching a lens to the camera so it retains color as he goes down, which is why it's red. Color loses its vibrancy the deeper down you go, and red is the first.
Yep. I did a bunch of diving some years back and enjoyed video and photography. I still have the rig and the lights. Red light wavelength does not penetrate through the water as deep as other colors do, that’s why it looks so washed out. So you have to add it by adding a red filter. Anyway, a haunting video of Yuri. I shudder at some of the stupid things I have done while diving but survived.
That’s good info
yuri’s scuba diving video was so stressful it’s insane. it got so dark so quickly and i can’t imagine how scary it all must have been once the reality of what happened set in. i hope he wasn’t aware of it for too too long
10:34 the camera is undoubtedly already in a waterproof housing. He's attaching a red lense filter. This helps underwater shots look more correct the deeper you go under. The blue light of the water naturally filters out the color red as you dive down deeper. A red lense filter will help add that spectrum of color back and keep underwater shots from looking dull and muted.
I was just about to say this!
Yuri case always freaks me out. I’ve seen his video before I really liked the way you presented it.the sounds of his breathes etc. give me a sense of deed
Yes. His camera and equipment did him in. Must focus on the dive, not camera. Also overweight can make bouncy a little more challenging. You have to be constantly aware of your depth, 5 seconds and you can be 10 meters lower. I was focusing on some white tip sharks at the bottom and before I knew it, was at 30 meters (only open water certified at that time). Depths are deceiving there and watch your PO2.
Watching his death footage really stuck with me, because it shows how quickly things can go south. One moment he was just swimming around in the bright blue water, two minutes later he is lying on the sea floor, surrounded by darkness and kicking up silt while drowning. A really bleak and dreadful way to die. It's shocking how suddenly everything happened and how this could happen to an experienced diver. It really made me respect the ocean even more and opened my eyes to the fact that recreational diving is really damn dangerous. Obvious in hindsight, but I never thought of recreational diving as particularily hazardous, it's a tourist activity after all. But now I know better.
@@chrisgant3409 white tip reef sharks sleeping on the bottom?
I had already seen Yuri’s footage but with the voiceover and explanation it is much more eerie and heart wrenching. RIP all divers who lost their lives in the Blue Hole.
I've seen it before and it still caught me off guard and gave me such chills 😢 what a horrid way to go
I have nightmares about being in the deep dark blue sea with nowhere to go and no direction to turn to and wake up in the most horrid panic and sweat. Now I've just watched this, definitely gonna have another episode tonight.
Ah yes, time for my prescribed dose of thalassophobia 😩🙌
Thalassophobia (from Greek thalassa θάλασσα, "sea", and phobos φόβος, "fear") is the persistent and intense fear of deep bodies of water such as the sea, oceans, or lakes.
I can not go in water without water shoes.... for some reason thats my only fear with water, deep water, rivers, ponds and lakes.. gotta have water shoes or flippers.
I like playing on beach and getting on boats, but once my body touches water deeper than several meters I'm scared
I have nightmares involving water all the time, but for some reason this channel soothes me with factual history and explanations.
@@UATU. Understanding helps us feel in control. I also hate the deep. Sounds pretty common.
I've seen this footage before, but it scares me every time. Still one of the most terrifying videos I've ever seen. That water was so dark, he must've had a moment where he realised he was finished. I can't even imagine what must've been going through his mind, gives me the chills.
I love this channel, but every single one of these videos make me want to never leave my house. lol
The red tinted lense Yuri puts on the camera is for making reds visible as that part of the visible light spectrum gets filtered out by the water.
i was a dive instructor and dived the blue hole (not the arch, 30m max) a few dozen times with guests. i did the arch (what you call "exit to ocean" in your drawing) 5 times, 3 times solo, with tec equipment, but on regular air.
i think you didn't do a great job describing the layout, the appeal and the danger of this divesite. The main appeal and reason people die is, they do the arch (>52m, tunnel) without qualification or equipment. its a connecting "tunnel" from the inside of the blue hole to the open sea, at minimum of about 52m, but open on the bottom to 150+m. Its absolutely stunning to dive through that arch, its like diving into darkness and then emerging from tartarus into the light and life of the red sea. its just a bit too deep for regular divers, but also, just in range, sometimes in view. a huge temptation. give some bakshish to the right diveguide and he'll take your owd-noob on a 12l tank. boom. gone.
what happened to yuri could have happened at any 100m+ divesite. or maybe he was initially looking for the arch?
This is the comment I was looking for. Capital letters would improve the readability of your large message. It took me a while to decipher “owd-noob”, I suspect you meant “OWD-noob” as in, Open Water Diving Newbie.
Anyway your message is ironic bc I found this by far the best explanation of the blue hole & arch yet, imperfect as it is. This is the first time I’ve seen this illustration. Everyone else uses the same low res 2D graphic.
The illustration here isn’t much better but it at least gives a comparison between it and the common one. Someone needs to do a 3D rendering or at least primitive 3D drawing to illustrate how this hole connects to the arch, and why is it even called an arch? Is it just a tunnel? All tunnels have an arch for a roof, nobody calls them an arch?
PS: I’ll give you some bakshish to re-enable your device’s autocapitalization
Thank you for saving me the time and trouble of having to watch the whole video. Which seemingly could be quickly summed up by noting that the vast majority of all of these deaths are due to people being careless or outright reckless and exceeding the limits of their equipment and/or training. Sad but wholly unsurprising.
Thank you for commenting, Dom. Ive never been diving so I have no idea of what "Blue Holes" where and
what made them so dangerous. Saw this video's thumbnail a few times on the front page and felt like it was time to watch it.
I am sure my local dive instructor said when I dived here. If your bubbles start going down instead of up swim backwards otherwise you're on an uncontrolled descent. Great dive sight. .
@@thelanehunterdevon1664 what's happening that cause the bubbles to appear to go down? Lost the bearings of down and up? Like someone in an airplane with no visual indicators?
As a diver these videos and stories remind me of one critical thing about SCUBA diving - we are not supposed to be there, underwater that deep. We put ourselves there and we prepare and plan so we are able to come back and tell our stories. Always stick to a coherent dive plan, always keep close to your dive buddies, always keep an eye on your depth and air gauges, always err on the side of caution.
As a commercial diver I can honestly say that deep water is truly unforgiving. If you don't go into the water with the proper amount of respect and careful planning, you could end up like these people.
Also I think a video on people who have died due to "delta-p" while working on pipes and dams underwater would make a great video. Imagine opening a 12 inch pipe 60m underwater and being forcefully sucked into it.
Hey, I just bought an open water scuba diving course, watching these videos is a little unsettling but they are good lessons. Was wondering if you had any advice for safety or just expanding my SCUBA experience.
@@ohhpiratenever dive alone. Always dive with someone familiar with the local conditions. I would also say keep track of your air and depth and where you are. It's easier to get separated than you think!😅
I've seen a video on this somewhere. Can't remember the channel. Maybe a Simon Whistler or Mr. Ballen vid. If it's the one I'm thinking of they get sucked in and have an air pocket and i think only one or two made it out?
@@ohhpirate Just pay full attention to your certified dive instructor and follow what you'll be taught. Then continue diving safely to build your confidence but keep your respect for nature by not getting cocky. Learning to dive is the best thing I ever did: ~2000 dives and I've never had any dangerous situations.
@@tomkagi3903you can have bad luck... I was doing a deep dive course with a friend who was one of my regular buddies. At 40m depth my breathing equipment stopped working properly, it just kept blowing air out at an incredible rate. It was painful on my throat, put it 20cm beneath my mouth so I could simply breath the bubbles. I lost 5-10 bars of pressure per second. Due to the rapid expansion it also turned extremely cold, my backup breather was useless because of that cold. By the time I was 5-10 seconds from having an empty bottle at 40m depth my buddy had his backup breather and gave it to me. We held each other tight (we had plenty of emergency training together) and went to the surface again with proper decompression stops. All was ok, but it was a very dangerous situation. It went from everything ok to very dangerous in a very short time. We did very regular emergency training together and nobody panicked and that resulted in a good outcome.
Just some bad luck with equipment failure.
I've dived in Dahab twice and I think it's as mentioned, the fact that it's so easily accessible from land and that it transforms from the sort of leisure diving any occasional vacation diver is accustomed to, to something entirely different very rapidly if one doesn't pay enough attention. As pointed out, on air you get narced pretty quickly when descending, and in this specific place you could potentially go from a bright, safe place where you can surface at any time to being narced out at a depth where you may not have enough air to safely ascend in seconds, if you're even able to get your buoyancy device to cooperate.
As for experienced divers dying there as well; yes, that's true, but in many cases they were people who had made a lot of not so complex dives, many not being on trimix, using single tanks of air and using simple BCDs, all of which are fine for reef diving at 20 meters, but not for deep dives. As far as I know there are not many experienced technical divers who were prepared for going deep who have perished there.
I dove the Blue Hole about 6 years ago. I was wary of diving regulations and equipment in Egypt, so I spent several days beforehand in Eilat (Israel) brushing on my skills and making sure I knew how to thoroughly evaluate any equipment I'd be using and that I felt better about being able to fend for myself. I'm glad I did. Some of the equipment I got even from a reputable dive shop was janky and my dive instructor (who dove in wearing denim shorts and a tshirt) paid very little attention to me in the water and I basically spent the time trying to keep up with him. Would have been very easy for something to have gone awry. It's an interesting dive site for sure (and Dahab is a really cool spiritual/hippy town) and I'm glad I did it, but to be honest the diving around Sharm El Sheikh is superior by just about every measure. Between the Tiran Straights and Ras Mohamad, the quality and variance in diving conditions is by far and away the best i've experienced.
Free Palestine
I believe several people tried to talk Yuri out of diving the blue hole as he wasn’t certified for closed circuit breathing. I don’t dive but even I know you don’t dive to that depth on oxygen. He made the same fatal mistake so many people make when wanting to try something new, they’re in too much of a hurry.
You can dive those depths perfectly okay on open circuit, you dont know what your talking about sorry.
See, this is why I don't just plunge into strange holes.
Be sure and strap up if you do

Man this is humbling. I was lucky enough to be certified through NAUI in a course at my university and our research dives were only in caverns. They put a huge emphasis on only to diving in terrains you were trained in and all of mine have been in caverns. Been pretty confident that caverns were the more difficult terrain but the false depth perception that comes with open water is no joke. Always dive with a 1-on-1 buddy!!!
What a sad story for Yuri. When I was training to become a diver there was a story about a couple of boys who went to Kullen to dive. Kullen is a peninsula located in the northwest of Skåne County, Sweden. One of them wanted to free dive and there are places where it is very deep so he had taken a lot of weight with him. As you have probably guessed, he didn't come up again - he sank really hard - probably got an ear squeeze on his way down into the depths. Poor boy. I tried it once during training in the swimming pool where I just for fun had twice as much weight as I should have and I landed on my ass a few seconds later. It hurt like hell, but I physically understood how dangerous it actually was to be overweight. As a freediver, I have used weight to descend, but the last deep dives I did more controlled. Respect the element and be careful out there.
I never freediver with weights because I'm swim snorkeling long distances too.
Below 10m I hardly need to kick to descent.
1:29 What is unsettling as well and must make Tarek’s work that much harder, is the fact that not all bodies have been recovered. Some families have expressed their wish to let them rest where they have fallen. I saw a video last year that showed the skeletonized remains that litter the bottom, and some fresh bodies as well.
100% of divers in blue holes wear a neoprene wetsuit. So there are zero skeletons at the bottom of this location. You are just repeating an urban myth that’s not even feasible. Neoprene wetsuit material will contain a body for decades before the material breaks down. You paint a morbid picture but it’s as false image
Utter boll ocks
Link to video?
Appreciate the video. I like your format and explanations.
I’ll keep watching!
I love the ocean and swimming in general but if my own set of lungs can’t get me there I’m good. The way these people die is terrifying to me.
👍👍👍
I know you were concerned about covering Yuri's story since it was so famous, but I'd never heard of it. So I appreciated this. Honestly I think you should eventually cover the most famous incident involving cave diving (the rescue part at least). The Thai kids soccer team. Yes everyone knows the basics but you do very in depth videos and I think you could make it in a way that really goes into detail that few others would cover. That would make it stand out.
People claiming it happened so fast are missing the whole point that he deliberately overloaded himself to go down fast. His descent was very intentional with the idea to do a "bounce" dive I guess so he could brag about how deep he went. The odd part is how ill prepared he was to dump weight and how he neglected to check his depth during his descent. They say overconfidence is a slow and insidious killer. Well it picked up the pace for him.

That’s a crazy video - 81 metres is seriously deep! As others have commented, it’s so deep that the normal buoyancy techniques don’t seem to have worked - plus he may also have been in serious distress owing to the physical effects of being so deep with just normal oxygen etc. Perhaps an issue is simply it’s so dark that divers may not realize how deep they are going without visual cues if they aren’t systematically checking their dive computers
Basically the only way to ascend in that combination would be to throw away your lead and hope that your stamina of kicking to slow you down will be enough to keep you barely alive for a decompression center.
But coming to such terms at a depth that prohibit any reasonable thought is already a low chance. And then even with reason, you will know that your chances are low.
I for one have never seen that fotage before. So I hesitantly say thanks for including it. Thanks, because it was very interesing and eyeopening. And hesitantly because... well. That's probably not hard to figure out.
Anyway. I only found your chanel a week or so ago, and I love it. Have been bingeing a lot of your videos. Never found much enjoyment in videos about cave diving/exploring since it felt mostly like one cave is just like other caves, but you make it really interesting and I'm having fun (among all the death) learning about different types of caves, how they look and their different challenges. Being european I also appretiate you including the metric system. So many videos just use the american system, and I'm left with just a vague idea of how big/small something is. Also, you could probably read the phone catalog and it would be a nice listen. Your voice is really pleasant. Thank you for making such great videos! Can't wait for more! :)
His problem started at the beginning. Screwing with equipment, bouncy control, switch on regulator possibly in “closed” position, experience. This is a very dangerous dive (like many around the Red Sea). Do not dive them without a guide, no matter how much experience you have. This includes Trimix divers. A professional guide knows the environment and will give you an added measure of safety. This is the first lesson you learn in open water diving. After you are use to the site and informed to its conditions, you are prepared to dive safely. I’ve dove this site. Quite an amazing place. Sad for these divers who lost their lives.
Losing track of your depth in deep, clear water is very easy. I've dove the wall off Little Cayman multiple times, and I have accidentally sunk from 70 to 100 feet without noticing, especially since I also tend to dive a little heavy. Thankfully it was a ten minute non-incident, but it really does come at you fast.
That happened to me when I was learning to dive because I saw a truck on the sea floor & I thought it was closer than it was. Luckily when I looked up & saw my instructor and my mother frantically gesturing at me I corrected my mistake.
In this video you can easily see he is diving very quickly. It is not difficult to spot, it is hard to process. Divers tend to not be very bright which is why they don't notice the indicators that allow one to estimate the speed, in the camera it is extremely visible based on the "white dots" floating.
I think the filter attached to the camera was a red shift filter. Especially before editing software became as prevalent as it is now, deep water videographers had to use some tools to properly represent colors at depth. Otherwise, everything slowly shifts blue as you descend and the video tends to lose a lot of its striking contrast.
This place is like Mt Everest except in reverse.. The fascination, the potentially fatal outcome, and the actual body count all have eerie parallels to Everest.
I live in Egypt and was in Dahab last week. There's a big rock where people's name plates are plastered there to remind people how dangerous it is. Otherwise snorkeling there is wonderful I never get enough of it.
What's the point of breathing air down a black hole.
Some freedivers could get to 50m for a quick look.
My heart sank when I saw him over 80m down with just regular air. At that depth he was probably dealing with both Narcosis & Oxygen toxicity, which I can only imagine is one of the most terrifying things they could experience… then his buoyancy control ruptured…. That’s when you’ve gotta know you’re too far to go back.
What oxygen should be used at such depth?
When Yuri first checks his depth gage it says 81 meters down. He pulled it out of camera view for 2 seconds (based on the camera screen time indicator) when he looks at it again it then displays 89 meters down. He begins to panic, because he knows he's in trouble. So apparently he was sinking like a rock, while thinking he was making a controlled dive? 2. Why didn't his dive partner grab his leg and warn him that he was going too deep? 3. If was an experienced diver, he should have known that pure oxygen would be ineffective at a certain depth. I apologize to all on this thread if it sounds like I'm "Monday morning Quarterbacking." I just discovered this channel a week ago and, I'm ADDICTED! When I was a boy, my father took me to see JAWS, 1975, never stepped into the ocean since. And I loved summer's at the Jersey shore! God I'm old.
You’re not that old
You can tell that Yuri is dropping quite fast due to how fast the particles in the water are appearing and disappearing from view.
He didn’t even slowed down his descent with inflating his bcd. A thing everyone learns at their first lessons.
The way he aimed at the bubbles..I wonder if he was trying to catch up with the deeper divers below him, rather than his slowpoke partner.
Very good video. As someone who has always wanted to go scuba diving and isn't aware 9f these invisible dangers, this video and others like it could be saving lives
I’ve dived in the arch and the blue hole here. In my view as a divemaster, the deadly element is that the blue is hazy in the hole. You won’t even notice the mesmerising embrace of the big deep blue until it’s too late. I saw it happening to another diver. Careful…
I discovered that I have a fear of murky water, when I jumped into a very green river, with a group of friends, and suffered an embarrassing panic attack. I can't even imagine how much more terrible that feeling would be, in pitch black water, way below the ocean's surface!
Skill issue
@@portablefrog2249empathy issue
I've never had a panic attack that I felt was embarrassing. If you were lucid enough to realize you were panicking, it wasn't a panic attack. You were just panicking.
@@portablefrog2249 more like a sense of self preservation
@@YFZriderdude15no? not everyone experiences panic attacks the same way? I've very much had panic attacks where I was still coherent. I can feel when one is about to happen as well
The scariest part about this is that it took less than 3 minutes for him to get to a lethal depth.
Woooo scary upload just at bedtime!! Love your work. Watching from Australia ❤
Yuri’s video is one hell of a disturbing watch. Especially since you see his desperation and hear his breaths as he sinks.
The first time i watched it it gave me nightmares
Underwater photographer here. The cap Yuri puts on his camera is a colour filter that helps offset the intense blue of underwater shots. The warmth of his filter is usually only for very deep filming - suggesting he always intended to go deep.
The "backside" of the Anacapa Islands are very similar in topology to this (not the same geology though). They sit right on the edge of the continental shelf, so the inland side is really shallow and great for snorkeling and recreational scuba. The backside of the island falls off to over 1000 ft almost vertically. My dad regularly worked as part of Bob Ballard's team and they would test ROVs out there because you could get 2000 ft of water under your hull a little over an hour from dock.
I saw Yuri's footage a couple of years ago. At that time it really shocked me. I didn't want to see it again. But this time your explanation helped me understand what was really going on. The fact that he had nitrogen narcosis let me realize why he kept descending. What a nightmare. Thank you Sean @Scary Interesting ⭐
Tarek is an amazing person for doing these recoveries and wherever he is, I hope he's doing well.
I went snorkeling once in a lagoon in Hawaii. It was the most amazing experience I ever had, swimming in a marine wonderland full of huge tropical fish and turtles. That's as deep as I would ever want to go, thank you very much.
I love how accessible your content is. The narration of the video footage was fantastic, and the captions are always well done. Much appreciated.
the claustrophobia i felt while watching yuri’s video 😭
yuri's mini panic screams at the bottom are horrible. makes you wish you could've helped him. it happened so quickly. it seems weird that he didn't realize to take his weights off, but nitrogen narcosis is pretty powerful. heard its similar feeling to nitrous oxide. I could definitely see someone just forgetting what's happening and loosing their mouthpiece. id rather fish, snorkel and swim than dive anyway. The ocean is scary as hell, especially at night.
Great video!
The really dangerous thing about this site is the outlet into the open ocean. It's nearly suicidal on a single tank of air (it can be done but you should likely die if you try).
Further, I think a lot of the deaths are people who get disoriented and swim towards to deep passage out thinking it's the way up. Because there is light on the otherside of the swim through.
Yuri was probably narced. He was too deep.
He only attempted to inflate his BCD once he was already out of gas (which he sucked through fast because he was so deep ofc). Its why he dies right after. I could be wrong but I don't think he attempted to blow his vest until he literally was out of gas. He was choking well before that.
The depth and weight is not a factor if you still have air in reserves. He also kept not eye on his computer until it was too late.
By the time he was looking at his computer he should have ripped his weights, attempted to blow his vest and, if failed, ditch his entire vest and tank and swim for the surface.
If he still had any air in his lungs he absolutely could have made a punt for the surface on a controlled exhale.
Situational awareness is everything diving. And this is one of the most situational awareness necessary dives you can do recreationally.
Rip Yuri - I hope your footage has saved many lives.
If he did it the way you suggest,he'd be dead before he'd hit the surface
@ppo2424 it's unlikely he was fully saturated, but either way, a self rescue controlled exhale at this point is very likely fatal. It's absolutely not impossible though. Crazier things have happened.
It's the diving equivalent of baling out of your plane. Pilots are taught to avoid doing it at all costs but they are still taught.
@@AArdW01f Yeah diving out of your plane without a parachute at a height of 10k feet.
@ppo2424
Regardless of how dangerous it would be - the alternative is drowning. Your line of thinking is backward - in advanced diving, you work towards self rescue any way possible until you actually die. What else is there to do?
Not every man who escaped USS Tang was washed off her tower or used a momson lung. Couple of those dudes did the slow exhale from near depth (she rests now at 175ft).
There is a reason PADI and NAUI teach this method to beginner divers as a last ditch. If the alternative is drowning you do what you must because flipping a coin is better than 100% drowning at depth.
For the love of God don't go attempting tests of this from the bottom of the Eygptian Hole.
The original point of my comment is poor Yuri clearly had some attention deficit to some critical dive awareness items. Possibly due to narcosis.
Danger is generally a function of how complicated a dive is and therefore how much the diver must manage to stay safe and on task. This dive seems, without having actually been there myself, to be easy enough it can be recreationally done but complicated enough to often overwhelm headstrong divers who push the limits.
It's a bad combo that
This is a good video it shows how dangerous the blue hole is. I was at diving the blue in 2010 it was a great dive and awesome to see but the tour guides did not make it clear how dangerous it is or how many people had died there. Only a few month later i found out how dangerous it is.
Dive Talk is a great cave diving channel that talk about these tragedies (and positive stuff too)
Seeing stuff like this makes me thankful I had such a thorough dive instructor. Initially I wondered if there wasn't something special happening causing gear to malfunction in these holes (water density changing suddenly or something). Turns out its all just human error caused by lack of experience and preparedness. Always keep an eye on your depth as you descend.. you could be in a downward current and no realize how quickly you're falling.
Ironically many of these deaths were of “thorough dive instructors” like the one who taught you
@@drdrew3 doubtful..
I know this video has been shown on yt a lot but you explained better than anyone .. thank you
I think I have all the phobias. Fear of heights, bodies of water, airplanes, tight spaces, spiders, elevators, tall buildings. I'm like that guy from "What about Bob" but hopefully less annoying
Baby Steps.....lol
I heard death therapy is a real blast.
@@MaiAolei the final Boss
The video is terrifying and shows how quickly even a well trained diver can find themselves in big trouble, he sank deeper than most apartment buildings in the time it takes to brew a cup of coffee. In a way it's an important cautionary tale no unlike the corpses on Mt Everest, a reminder for the divers who've seen it to turn back/not dive in places/at times when it could otherwise have led to their demise
The periodic squeaking while Yuri descends is likely him equalizing pressure on his ear drums. Depending on the diver's physiology, this can happen naturally with breathing or by holding your nose and 'blowing' out it, forcing air into your ears. I have to do this manually while diving and it makes the same sound on camera.
Divers are insane. What's there to see underwater? Nothing worth dying for.
