Finally a diving video in which the youtuber actually talks.
Great video pal, continue the good job
Thanks Aymaan!!
This is what I need work on. Thank you from a baby diver ☺️
Try making a dive where you are intent on moving absolutely as little as possible, as slowly as possible - and on using as little air as possible. Do it for about an hour as a kind of meditation. That will teach you a whole lot about a bunch of different things.
aaaaaiiiiii very much agree!
One thing that many neglect to mention is that buoyancy checks are supposed to be done with a cylinder at reserve pressure, but they are almost always done with a full tank. As such you need to know how much the air in the tank weighs. For the typical aluminum 80 that is 6lbs, so you need to add that on top of the weight needed to achieve neutral buoyancy with a full tank, or else you will struggle on your safety stop at the end of your dive.
You're completely right! We didn't mentioned that! I will pin your comment to the top! Thank you
I want to make sure I understand what your saying here, since I do my open water this coming weekend. So I need to set my buoyancy with the Air cylinder at the level I have my reserve set at.
No. When your air cylinder is full it weighs about 5-6 lbs (approximately 2kg) more than when it is empty. Thus if you do a buoyancy check with a full cylinder you need to add that much weight to your weight belt/pockets so that you will be neutral when you are nearly empty. Because when the cylinder is empty that is when you are at your lightest and most buoyant during the dive.
Rgr, Thanks I'm going to the pool today and work on my buoyancy control. right now I feel like an underwater bobber.
"One thing that many neglect to mention is that buoyancy checks are supposed to be done with a cylinder at reserve pressure..."
So you can't do a weight check for your very first dive? Or you have to switch to a full tank AFTER doing a weight check? Nonsense.
I just completed my OWD and your channel helps a lot. Thank you 😍
As a novice after getting my AOW, this was a great tool in helping me understand the mechanics/physics involved. I plan to look at more of your videos. Thank you.
Thank Avery! More video's are coming up!!
Great video! Finally someone showing some usefulls tips and skills in recreational gear!
Thanks Marly!
Short and Sweet ... Thank You
New diver .. struggling with this...first video that actually seems like tips I need. Thanks
I used some of these tips yesterday!! Helped tremendously. Especially the dump valve trick. Training tips that I didn't get from my basic course instructor.
More vids please.
Thanks!! So glad to help!!
Thanks. Great buoyancy control demonstrated. Something to aspire to, but as the script says it's not quite that easy to master. Personally I still find it a bit unnnerving to feel my gentle descent accelerating away from me as my wetsuit and other pockets of air compress. Then as my air is getting low, to find it difficult to maintain depth, even with almost no air in my bcd. As the video shows, one thing I've learned is that using the side dump valve is critical to managing an ascent
Thanks for the video, some really good advice.
Best boyancy explanation on youtube. Thanks!
Very nice! Just received my OW Certification last weekend!
Thank you keep them coming !
This was a great video! It was very helpful. Thank you guys for creating such good content!
Excelente video, gracias por la info. Así puedo mejorar mi boyancy
This is pretty awesome for the beginner diver!
Glad to be of help Cameron! Did you see episode 2 already? th-cam.com/video/hkpeT_xQw7g/w-d-xo.html
I've learned so much. Love the content.
Great video! Excellent video. Thank you
Thanks!!
Really helpful thanks so much.
I really like the wrong way/proper way filming, it is both funny and informative.
Thank You for Sharing.
👍🤙 Thank you dive buddy that was good
I probably watched all videos about buoyancy right know. I find it very good and easy to understand 😊🤙
Thanks Vod!
great video, thank you
That is awesome! Thank for the lesson.
Thanks!!!
You are a good teacher. Thanks!
Thanks Ron!!
Superb video!
Thanks for the video! Some helpful tricks :-)
Excelent. Well done.
cool stuff!!!
Thank you. I was always wonder why i always i never get neutral buoyancy. now to practice
Excellent video
Excellent educantion video for open water scuba divers
I subscribe your channel after watch this video.
Wow thats an amazing pool to be able to use for scuba
It is a really awesome pool, it is 10 meter deep. So nice for training.
50ft Below where is this pool?
@@WaterlineShorts it is loct in Enschede in the Netherlands
Excellent description. Thank you.
Super clear, thank you so much!
Thank you for your nice comment!!
@@50ftBelow I don't know how to swim 😥😥😥
Awesome 💙 💙 💙
Great video & good tips .. tq
Thanks for your comment!
Thank you ❤
You'r welcome Eva
Great pool. ;-)
Thanks!
Thank You Too Much
Great video! I wish I can practice in this amzing pool!! where is it? I think not in England 😹
I'm slightly negative buoyant with 8lbs. i dont did with wetsuits. life is easy ^^
Helpful
Good video. Correct weighting and then correcting my trim so I could hover horizontally was a big step in better buoyancy control for me, since I stopped moving my fins and hands all the time and could see what effect my lungs and BCD were having.
I bought an xDeep sidemount BCD where you can distribute your weights along your spine, which made it easy to get a horizontal trim.
Great to hear! Sidemount is awesome!
I still sink like a rock no weights in fresh water in the summer 🤣
Calculator is a good idea, but what about other bottles like 12 or 15 liters, steel and alum ? Thx
Thanks bro :)
You'r welcome!!
That very long yellow hose needs taming!!!! You are going to snag it regularly. A few more "quick release" retainer clips required I think.
I have some good news, the hose has been tamed!! All jokes aside you are right, that hose needed to be shorter but it was a loaner which I was testen for a review!
Can you please upload a video tutorial of floating on surface with fins and set
Positive 2.5lbs with near empty al80. Dive negative instead of neutral, unless you are using steel tank
Perhaps i'm stupid rigth now😂🙈 bur i cant seem to find the actual calculator when i Follo the link😂 Nice video 😁😁😁
I can’t either it doesn’t appear
Video is very helpfull well prepared. Thanks.
The calculator is wrong. Gives 2 times more weight for experienced, 4 times more weight for new divers.
Thanks for the heads up! We are updating the calculator at the moment!
Today i got my CMAS P1 CERTIFICATE WOHOOO!
Congratulations I am starting mine tomorrow
So I dive in 6 lbs, I started with 10 but lost some weight and felt like I was always being pulled down so I talked with my instructor and we did weight checks with different amounts and 6 pounds has been working great for about 10 dives now. I used your weight calculator out of curiosity and it told me I should be diving with 19 pounds ... so you might want to check that algorithm and maybe take body shape/height into account. Your recommendation is more than triple what I actually need and that seems like a very unsafe recommendation,
Thank you for the tip. We are currently working on a updated version which does exactly that
Thanks for the video, very helpful, good simple advise. Just a question... If the amount of weight I need is based on physics (as explained on the video) why the level of experience influence the weights (in the calculator) ?
Thank you for your nice comment! The level of experience is in the calculator because a novice diver doesn't have the skills of a experienced diver. So two things can happen, a novice diver wil start the descend with full lungs. So you need some more weights. A experienced diver will always empty there lungs before descending. Besides that a novice diver sometimes can't hold his fins still before descending so he will remain on the surface. That is the reason why we include the level of experience in the calculator.
@@50ftBelow , excellent answer. Could u clarify why a diver should empty his lungs before descending? (and i guess, fill his lungs before ascending)
@@rgudduu You need to breathe out while ascending I believe.
0:28 👌🏾
i think a lot of divers not using the bpw system forget about their dump valve
True True Bryan!
Thank you
1:40 Ascent,you meant Descent
When I tried open water diving in the pool I had a lot of buoyancy problems. If I were to remain perfectly still, I would slowly tip face down. If I was underwater, I would start tilting sideways. The instructors couldn’t fix this problem even after two weekends. What is the cause of this and how do you fix this?
I have a question for you ... I am a large guy. 6'2" (1.88 meters) and 250 Lbs (113.4 kg). When I wear a full 7mm wetsuit with gloves, hood, and boots, I need 28 Lbs (12.7 kg) of weight to be neutral at the surface with a full tank. I found that adding 2 extra lbs (0.91 Kg) helps for the end of the dive. My problem is that I can not hover. Or stay horizontal. I am all over the place. Could that be weight distribution? I have my weight split into thirds. With 1/3 of my weight in each ditchable pocket, and 1/3 split in half between the trim pockets on my back. I'm using an Aqua Lung Axiom BCD. I'm wondering if that is too much weight in the trim pockets? Any suggestions of what might help? Thanks!!
I think it has to do with trim. If you can, try to have a buddy go with you to a diving pool, and bring a tank, regulator with long hose and a couple of weights. Does not have to be the full weight you use. In your trunks, submerge yourself in the platform or shallow part of the pool while breathing from the longer hose. Now, with the weights, I'd say 2-3lbs. clasp them with both hands and bring it first to your chest, checking for neutral buoyancy as you move your weights downwards. It works differently for everyone. Your buddy will help you confirm the proper trim.
Don't forget to add extra weight when going from fresh water to salt water 😉
Good tip!!
@@50ftBelow I've been wondering if there's a formula for that. I know a lot of it is trial and error, but questioned whether there is a good starting point.
weight checks (descend when lungs empty, float when lungs full at surface) should always be done with a near empty tank......If you do them as shown in the video, with a full tank, at the end of the dive when your tank is low, you will have trouble staying down at 5m for the safety stop and you will be positively buoyant even with an empty BCD.
Important thing to note is that it depends on your tank. Steel tanks are negatively buoyant in most cases and some tanks are neutral. If you are diving with other peoples equipement make sure to ask.
Jester Even with a steel tank you need to have the tank near empty. Yes, it’s most likely negatively buoyant even when empty, but since it weighs less and has the same volume, it’s less negatively buoyant when empty, pulling you down less.
@@Jester-rm9ox even though a steel tank is negatively buoyant, how much it’s negatively buoyant matters. If it becomes slightly less heavy and therefore slightlyyy more buoyant (although still denser than water), you end up impacting your total buoyancy. Science, bruh
But you also need to consider that a wetsuit saturates during a dive and becomes denser/heavier, because more and more of the air cells inside a wetsuit fill up with water during the course of a dive… so, because of this, you gotta consider that too.
What I found is, if I’m using a wetsuit and a single Aluminum-80 (standard air) tank, I hop in with a just-got-wet-a-minute-ago wetsuit, and I just add one extra pound with my “full tank of air”, and I’m good to go. And that usually does it for me, i don’t add more weight cuz I know my wetsuit will keep getting heavier/denser/more full of water during the dive.
Now- If I’m using a tri- laminate drivesuit, I add the correct amount of extra weight, since trilaminate drysuits don’t really take in any extra water
How do you ascent horizontally without using the fins?
Where is the weight calculator you are talking about?
So you can always spot a group of new divers as they're all swimming around with their arses in the air lol
noice ill try it once the corona virus is gone
My main issue is i have to do everything i can and fight so hard to keep my legs from floating straight up in the air in a wetsuit idk why it happened but the instructors at class just looked at me and moved on like and skipped past me every time but when i didnt have the wetsuit i didnt struggle at all with keeping myself straight lol
I don’t know if you’re still having this issue but it’s your fins. Try some heavier or denser fins.
Thanks for video . Where was it taken ?
You're welcome! It's filmed in a dive tower in the Netherlands
how deep is that bottom?@@50ftBelow
When i did my open water course they told me when I go up I should look up and put my hand up to the surface, in this video you show a totally different way, what is correct
This is emergency ascend, not suggested
I do like the calculator, but I have a unique situation that I wonder if you can help with. My full wetsuit is 7mm, but I wear a shortie over the wetsuit that adds another 7mm. Typically I dive with 40lbs of weight, 14lbs on a weight belt, 10lbs x2 my integrated weight pockets, 3lbs x2 in my trim pockets. Sometimes I sink without weights in the trim pockets, sometimes I need the weight. I'm definitely finding this one of the most challenging bits to my diving. Any suggestions further suggestions would be most welcome.
If there isn't anything different in the gear you use you should always sink without the trimpockets. Things what might affect this is your breathing pattern. If you are breathing a lot your lungs are filled with are a lot of times and this keeps you a float. So next time try to calm yourself down before descending. It also makes a lot of difference if you are upright or lying down on the surface. The upright position is preferred since this gives you the least buoyancy. Hope the answer helps!
@@50ftBelow My last two dives I tried without trim weights. I did a buoyancy check at the beginning of the dive and all was well. I started my decent vertical and switched to a horizontal position once I was a couple of meters down. Both dives went much better. I still have tweaks to work out but, practice, practice, practice.
dharmapunk5 -- I'm in a similar situation to yours. I wear a 7mm "Farmer John" suit (7mm sleeveless jump suit plus 7mm jacket), so I have 14mm total on my torso. When diving in salt water people are shocked...even my instructors -- at how much weight I needed in order to get off the surface. A big problem with all that foam is that it really compresses under pressure, so once I'm below 20 - 30 feet I start sinking like a rock if I don't stay on top of my BCD inflation. Then on ascent the reverse happens and the foam expands, so I have to make sure I'm venting rapidly on the way up. It's a lot of work, but it was the best solution for me for diving in the cold waters of the Seattle area.
@@seikibrian8641 I recently did a rescue diver course, and during the exercise where I swam to a tired diver at the surface, I had my weight belt on but not the rest of my kit. On my waist, I wear 14lbs of lead and I was floating at the surface like nothing. All that neoprene makes me very positively buoyant. But as you mentioned once the suit compresses if one does not put sips of air into their bc to control the decent, one sinks like a stone. That happened to me on my last dive, my first experience of narcosis. Luckily I knew what it was and how to deal with it quickly.
@@dharmapunk5 Happened to me on my first deep diving course dive. Started sinking rapidly and freaked out at 60 feet. If only I'd remembered to put a few sips of air in, it would've saved me some serious apprehension!!!
Is it just me or are most seasoned divers in a competition to take as little weight as possible? I have noticed this whenever i say i dive with x amount of kilos they say im taking too much but when we shallow up at the end of the dive i see them struggling to maintain depth. I just do as said in the video although i take an extra kilo just to make sure i can stay down at the end of the dive.
Calculating weight link is not working. Please fix it. Thank you
Cool Video, but the calculator is way off for me. It is saying, that I need 10 kg, but in my last dive 7 were already way to much
“Too” much
What's a name of facility u use to film all your video, I wish I can visit
It's diveworld enschede!
You reiterated what you do for descent and ascent you didn’t cover the body mechanics. What you told me is the same thing that I read in the book but what are the body mechanics to actually accomplish these techniques?
New video's are coming and we will touch on the subject! Thanks for your comment!
Did you do this video
Calculator page is offline
The calculator doesn’t show up only the steps on how to use it show up for me how can I fix this
I learnt to put my hand above my head while ascending to avoid any obstacles to hit my head. is that right?
That's right but only do this for the last part imo. You also have a buddy which should keep an eye out!
Emergency ascend, not suggested
Hey your website link is broken. No certificate

cant access your site the browsers says certificate not valid and may be a malicious unsecured site. Wont let me go to your website or the calculator
Weight calculator doesn’t open.
I mean, these skills are all taught at open water as well, right? All the people who took the same class of open water at least got the theory involved in all of these. Just one thing: once a diver is weighted so that he or she goes beneath the surface of the water only on a regular exhale, should't one add 2kg to make up for the weight in air that's not going to be there at the end of a dive? That's what PADI teaches
🐕🐕🐕🐕🐕
Calculator seems to be broken
I see the instructions to fill out the calculator but no actual calculator???
Hmm, strange it's working fine here. You have to wait a second for the calculator is loaded! www.50ftbelow.com/scuba-weights-calculator/
Doesn't work for me either... 😔 I'm wondering if the calculator only works for iphone? Anyone able to open calculator on an Android?
Yep. No calculator. Too bad. I tried loading it in Safari, Google, and Google Chrome. None of them worked. I’m using an iPad.
Link broken
Calculator doesnt work :(
If you won't let me use your calculator without phishing my email, you can stuff it where the sun don't shine!
Vague info
How to control your buoyancy:
Don't worry about it, your DM will keep you at the right depth
why das your calc need my name and my email?
What wetsuit is the girl in the thumbnail wearing?
I'm not sure. It's awesome though!
Forget this nonsense and try freediving instead!
