For neoprene westuits, they are actually a foam made by pushing nitrogen into rubber. The thickness of the wetsuit doesn't mean less water comes in. It means you have more volume of Nitrogen between you and the cold water. Nitrogen is bad heat conductor so it insulates you, slowing the rate at which your body heat spreads into the water. Wetsuit Thickness isn't a measure of "watertightness". It's the same principle as wearing a thick coat in winter, it traps more air in between you and the cold outside. I hope I explained it clearly and did not forget important details.
With everything going on in the world today… it’s SO cathartic, relaxing, and JUST PLAIN FUN, to kick back and engage in some learning & laughter with you two wonderful fellas! From the bottom of my heart: Thank you, Woody & Gus!
I really liked that Gus gave five of his own facts at the end. I especially appreciated the accessibility PSA about diving being for everyone. Thank you both!
Hands down, this is the most entertaining podcast (or whatever you call it) I've seen in a long time. These two guys are priceless. Funny and witty. Perfect combo. Keep up with the good work guys.
Found your channel recently and I've been OBSESSED! You guys are so interesting and informative. I've always seen scuba diving as something terrifying - I've only done a 1 hour class in a pool - but you guys are so passionate about it and by the book, you've certainly left me more open to the idea in the future!
Non-diver here. Love this channel and videos. Woody and Gus’s personalities complement each other very well. I also like how despite being expert in the area of diving, you guys remain humble and educational!
Honestly, hearing an experienced diver say scuba diving is for everyone is so heartening. I’m a 23-year-old cane user with chronic pain that limits what i can do outside of my home, so I long ago wrote off a lot of the experiences most people put on their bucket lists. Despite this, I’ve always had a love for the ocean (I’m a certified sailor!) and have been curious about scuba diving with my brother since he got certified three years ago. I’ve been falling even more in love with scuba diving since finding this channel, and I’m seriously considering looking into some classes now. Thank you for sharing all of your knowledge, and for just generally being really great guys
Definitely do it. As long as you let your instructor know your limitations OUT of the water, they'll be able to accommodate you. Once you're IN the water, you won't know yourself - you'll be free! I've dived with someone who had terrible arthritic pain who said that their pain was significantly reduced whilst diving as there was less pressure on their joints while they were underwater. We carried their kit for them, got them kitted up in the water and helped out generally until they submerged. Once underwater they were an absolutely brilliant diver. Your buddies will always be more than happy to help out however they can so don't be afraid to ask for help if you need it - we're all there to help each other enjoy the dive, whatever that takes, from carrying kit to holding someone's hand if they're nervous. Go for it - you won't regret it.😁
Woody is a good man he teaches disabled people to dive. As a non diver I love this channel thanks guys. Going to S. Florida in a few months would love to make my first dive
The prefix has Latin and Greek origins, their way of pronouncing it would seem more accurate to its root. Out of curiosity, how would you pronounce triple? Same root.
After not diving for 9-10 years, it has been refreshing to find this channel. It is great to be able to appreciate and re-imagine the underwater environment. I received my Open Water Diver - Level 2 at around 2,650 feet.
Guys, it is a fact that the insulating properties of a neoprene suit depend on the quality of the polymer used and the number of air bubbles that the manufacturer can insert in a controllable manner in the polymer mass during fabrication. The thinner the bubbles and the more of them per cubic mm the better the insulation. The thicker the material more bubbles you have, and THIS is the reason a thicker material provides better insulation at the expense of increased bulk and reduced flexibility.
I couldn't begin to imagine the feeling of looking out over the ocean. Let alone DIVING into it. Absolutely mind boggling. I would love to one day. I'm from Nebraska, where there are waves of sand in the great plains. I'm thrilled to have found your guys' page. I appreciate the time, and work you all put into these videos!
According to wiki, they may actually be right about the nitrogen bubbles in neoprene: "Wetsuits are made of closed-cell foam neoprene, a synthetic rubber that contains small bubbles of nitrogen gas when made for use as wetsuit material (neoprene may also be manufactured without foaming for many other applications where insulating qualities are not important)."
pretty sure this was mentioned in the ''Encyclopedia of recreational diving'' I studied for DM'. I could have also read it on a manufacturer website though. For production Nitrogen gets forced into the websuit to make it foam like. Guess it does help with isolating the thing layer of water a little bit better BUT the main principle like Woody said is the water trapped on your body, as far as I understand it.
I am surprised that instructors laugh about someone else says, and I am even more surprised, if this is correct. But at the end of the day it's entertaining.
that is probably how neoprene is manufacture for the market so they need to use nitrogen to produce a foamy reaction in a liquid state where with air is not possible, but in general but the only impact of neoprene towards a diver is how thick the fabric as a suit is to give the diver a comfort against the cold water as barrier of insulation...no wetsuit company has ever claim to have a special nitrogen fabric as a feature for their suits because is irrelevant....basically neoprene is just a specific density foam that does contain trapped bubbles a a structure and use as a fabric for underwater suits.
About the Nitrogen thingy, the same principle applies to your regular thermos. Instead of having a single wall, thermos has double walls with cavity in between them. In cheap thermos, this cavity is simply an empty space filled with air. In high-end thermos, this cavity is vacuumed (of course not fully vacuumed). Air (or gas in general) is a poor heat conductor. Thus, the thermos can retain heat inside it (for hot drinks) or slow down the rate of heat transfer into the drink (for cold drinks)
Thanks for clairifying!! As a non-diver, I LOVE ur channel btw, I always thought the deeper u go down the more the weight of the water tries to crush u..so like somehow u always felt some pressure on ur body ..so crazy..not sure why I thought that. You guys explain things so well, it is absolutely not so scary sounding any more the more knowledge you guys flow! Thx guys!!
Ya'll are hilarious! Love how entertaining your videos are while also being educational and giving something back. Also, I can totally relate to being annoyed by those pesky remora... had one nibble on my ear.
Hey guys, I've been waiting for the Top 5 or 10 things you should know before cave diving!!! And how to be a cave diver itself step by step. If that would happen, damn. This channel is gonna blow
Neoprene is manufactured by foaming the rubber with nitrogen gas, where the tiny enclosed and separated gas bubbles can also serve as insulation. Nitrogen gas is most commonly used for the foaming of Neoprene foam due to its inertness, flame resistance, and large range of processing temperatures.
i love you channel and have been here from the beginning. IMO your best content is when your bring on fellow divers and tell real stories. Sorensen, Young, etc those stories are riveting
Paul, if you are referring to the Byford Dolphin tragedy, I am not sure much educational benefit can be gained for the wider sport diving community by visiting/presenting that video. That said, having the GREATEST respect for - and wariness of - our ol' buddy Delta P is a must for anyone poking their heads underwater.
Great as always guys. And to Gus’s point about diving being for everyone. I’m 51 and just got certified this year after wanting to for many years. Anyone who wants to do it just do it. 👌
i think he was saying the bubbles keep you warm and not the material. the bubbles make an air barrier between your skin and the outside water, the same way insulation would work in a house. its not the material in the insulation that actually keeps the house warm, its the air it traps that makes the heat barrier.
I love how Gus and Woody reacted MORE to the random "20 metre club" throwaway comment than any of the top 5 diving facts bahahahaha. In honour of Watchmojo, I present my own top 5 interesting Woody wish facts: 1. Prove octopuses are aliens. 2. Blow up a jetski. Bonus points if the jetski is pink. 3. Penetrate the Las Vegas NV hole. 4. Flashmob dive with Gus, Mike Young, Ed Sorenson and the Dive Talk fans. 5. Join the 20 metre club. When Gus is overly sarcastic and Woody is practically speechless, you know you done goofed. The "trimix" comments were gold. Have a great weekend guys! Another good video :-)
There is sooo much to learn about diving, in any capacity. I don’t think in the UK (where I live) the places they teach are very luscious in fish and coral varieties. However, from researching there seem to be decent diving schools. After watching your videos it’s been highlighted to me the paramount importance of finding reputable teachers!Who in turn teach the correct and safe ways to dive. So I don’t suppose it matters where you are taught so long as you are learning the correct skills/ techniques etc so you are safe and have a great time too! Thank you for your videos
The amount of inaccurate info on the internet is amazing...and frightening!It is very important that everyone does their own research and consult professionals in the field. On another note, "tree-mix" is even funnier than "Jacques Cousteau". Great video as usual.
I am afraid of getting in the water. But somehow I came across your channel and I have learned so much from you guys. I feel like maybe if I learn more it will help me overcome my fear. Thank you guys and I love how well you explain things especially for us non divers. Much love from AZ 🌵
Go snorkeling and freedive a little bit. When you can go 5-7 meters deep while equalizing, you gain confidence! Also, practise clearing your mask/clearing your snorkel and freedive without a mask. The more you learn in advance, the less the diving yourse is intimidating! And my final tip: Do static dry apnea exercises! That way you get accustomed to the feeling of not breathing, so that it will no longer cause anxiety. 2-3 minutes of static dry breathhold or more gives you confidence under water. During the owd course, you do things like taking out your regulator and putting it back in, which takes only a few seconds. If you never held your breath for a prolonged times tough, this exercise can be stressfull. But as somehone who can hold your breath for a while, this exercise can no longer freak you out! Other ideas that cause anxiety are: Loosing your regulator or failure of the device, out of air problems, not reaching your buddy quickly enough when this happens.... It all comes down to the fear of not beeing able to breathe. The longer you can hold your breath, the less scary this becomes. Don't get irritated by the noise of the bubbles and the regulator, or the clumsyness with the bulky equipment. You will learn to use quickly. Have fun!
Doing our deep dive certification at Blue Grotto, my dive buddy afterwards said “It felt like microdosing” absolutely narc’ed on himself. (Scuba was collage PE credit)
@S M blue grotto is 100 feet I feel like it is a more less, but it’s right around 100, and the statues are probably 80 to 90. But we were multitasking, class of 20 or so, some where gettin open water, some rescue diving, we did a night dive same day at Devils den, that was 2016. Deep Diving through padi is only supposed to certify to 130 feet. We went to destin afterwards. I think the padi certification deep dives only require you go below 80, but don’t quote me on that lmao.
Honestly, Mojo's top five was just a glance of what SCUBA is. But Gus top five allows people to understand that it is easy to get into the hobby. For example, his response to people being disabled clears up a lot of fears people may have. I am not in the best of shape with my lungs and my bones. Looked into the training but what put me off was the fact I needed to have a doctors note granting me permission to train. Maybe in the future I will be able to learn how to dive and get more involved in the community, what Gus said really helped that.
Soon as I heard the bit about nitrogen in the suit, I wondered if it was a misnomer. Then I looked into neoprene and apparently wetsuits are produced by bubbling nitrogen gas (essentially inert) through the neoprene (liquid) whilst it's curing, producing a foam. The nitrogen bubbles that are trapped provide additional insulation.
having use many brands and worked in a scuba shop ,about wetsuits, it does not matter what type of "air" is made of , it has no effect on the skin of the diver and actually I have not heard from any mayor wetsuit company to claim "air" bubbles features in their watsuits , they go by the elasticity and thickness and backing of their special neoprene and the insulation "warm rating " comes from the thickness of that neoprene ,where is located (torso, limbs,etc), and where will it be used (water temp) neoprene is a water proof membrane (some drysuits are made of it) , the water that gets inside a wet suit comes from the cuffs.neck,zipper ,etc and that water is what lubes the inside so it then that water between your skin and the suit lets the suit move and from to the body when it could not do it when it was all dry (the lining inside of the suit matters) ,the film of water touching your skin gets warm by heat transfer and the suit holds that inside heat depending of how well the insulated rating and or thickness the neoprene is (quality matters, thickness matters), sometimes my 5mm suits become too hot because of the water temp is too warm so I have to let water in to cool me or I began sweating underwater and they should fit tight like a seal skin so very little outside cold water trickles and moves inside or you will feel that cold water rushing and making you shiver at times, rash guards beats the purpose of a good seal , I know a tight suit feels too tight at the surface but under water it is preventing from the cold water to fill those creases with cold moving water... that`s my sales pitch and understanding of wetsuits and how they work from years selling and using them ,etc...yes they will compress over time and lose their thermal protection so get good quality ones that will last you for many years more than a cheap one. Drysuit are a complete different animal that also has cons and pros... I love wetsuit diving here in the cold waters of California ! just my two cents. cheers !
You can make neoprene into a smooth synthetic rubber. Wet suits are made of foamed neoprene. They don't use nitrogen particularly because it's a poor conductor of heat; it's obviously not far different to air. But it is unreactive in the foaming process and it does suffer less from diffusion out of the material over time because all the smaller molecules have already been taken out. As you say, the major factors in effectiveness are thickness, resistance to crush and control of flushing. 'Altitude' diving clearly does not all take place at 1000ft AMSL. He clearly means '.....is defined as...1000ft or above...' 'Trimmix', brilliant! One of those youtuber examples of someone reading off a page with no idea what it means. But overall, surprisingly true. So good job by Mojo! I like your top five, and in support I'd add that I started diving aged 56 and have loved it through the basics, twins and, as of last week, sidemount. New skills, new experiences, new places and new friends.
Yes nitrogen is a key component in wetsuits. They are made with what is called gas blown neoprene where they make nitrogen bubbles in the neoprene to give it insulating properties. Neoprene for scuba has more but smaller bubbles than say neoprene for surfing because at depth the neoprenes would compress differently.
@@DIVETALK Definitely not. I am surprised that they didn't cover something like "Fact number 1. Water. When scuba diving, whether you are in the ocean, a lake, a swimming pool, in the USA or on the opposite side of the world, you will likely be scuba diving in water." Sure it might be a fact, but it isn't intriguing. Titles matching content can be important. Such fun facts, interesting facts, horrifying facts, disgusting facts, etc. For "top 5 facts" the person putting it together should really bring their A game. Keep the videos coming. We love them. 👍
You are right about the wetsuits as far as the element of it with which you can interact . But the neoprene itself is 'air gapped' using nitrogen which is what creates the insulation value. Like how in a building, a 1' air gap is better r value than 7" of high dollar foam. It just uses trapped nitrogen gases to do the same thing.
I think a cooler top 5 would be (Im a non-diver so this is stuff I find interesting) 1. Dive talk 2. Finding nemo 3. Woody drinking coffee 4. Cave diving 5. Taking gus dry caving
Wouldn’t the water in the wet suit both get heated by the body and chilled by the water on the outside? I guess that equilibrium makes it not warm but not cold either?
I would be really interested in you guys talking more about diving with physical challenges, especially since Woody is trained for it.. if you had some clips to show us it would be even better! Thanks for all the great videos
warmth of neoprene is all about insulation, the thicker layer keep cold away from your body, just like jacket on surface. The fit of suit keeps water circulation to minimum but is not affected by thickness of neoprene rather than cut of it. As you dive deeper, the neoprene will compress and gets thinner and thinner so you get colder and lose plenty of suit buoyancy. And holding breath is another topic, you are not literally holding breath (like freediving) but definitely changing breathing pattern to affect your buoyancy and use your lungs for ascent and descend more than your bcd (CCR is exception because of counterlungs).
11:58 unless you go nightdiving, for which a light is mandatory, then all the colors are so pretty, you can't even believe you're in the same place. Did a night dive in Croatia, in a small reef at 40m for my advanced open water training, there were so many colors, fish were sleeping in crevasses all around me and the largest number little crabs in spiky shells I've ever seen in one place. Man, I'll remember it till the day I die. A camera would have been better, but I didn't have one that could go to 40m.
Wait you mean you guys don’t carry around a wetsuit fill adaptor? I just top off my wetsuit before every dive with my nitrogen tank and then use it for the dive while I mouth blend my mix so I can have a continuous change of mix as I dive😜 another great video! Keep up the excellent work!! Also props to the community for coming together and sharing your knowledge with us! I know I appreciate all the information you all share with us as well!!
Thank you so much... not everyone has great holiday days and I know I did wonderful with the food, but all I could think of was diving and your videos 😆 I love you guys and went from being afraid vs real life fun to be be real and I soooo want to do it badly but I know I have MS and I I need real open water training.
Well I see Mike's Big Adventures already made the comment so I'll second or cosign with him. Your top 5 was definitely interesting, all 5 were not only things I didn't know but a few were the opposite of what I would have assumed, like not feeling the pressure, I mean I wouldn't think you're being crushed but definitely feel a difference. As usual great video fellas, I don't know how I started getting your videos but I'm glad I did
As stated in the video, pressure on the body, itself, has no appreciable effect whatsoever. During the Predictive Studies IV project in 1975, we were at a storage depth of 1,200 feet, and made 'jumps' down to 1,600 feet. No difference at all in physical impact. Sinus issues or gas pockets under abscessed teeth can be a problem due to the compression of 'air' issues.
@@Coffeeguyzz Wow, now that's frigging deep brother, are you a Sat. Diver.I think what "tricked" my mind into thinking that way is forgetting or not really thinking that the body is like 70% liquid, because I know water and other liquids do not compress. As a Toolmaker who has spent a majority of my career making and building different custom one-off machines we will fill cavities with water trout before pressuring with compressed air( huh huh see what I did there?) to check for leaks.
The words mix and tri are adopted from the acient latin and Greek words mixtus and tria. Also the Latin scientific name of nitrogen is nitrogeneum and its original name coined in France is nitrogene. So you could say that the pronunciation of knee-trox and three-mix are correct 😬. We pronounce these mixes like this in italy.
I was in the Bahamas, I went snorkeling with barracuda, the operators threw our chicken bones left from lunch in and they didn’t bite a single person, I always get frustrated when they are blamed for “shark”attacks.
Great info..I always wondered how those free divers going for world record depths could hold their breath and not feel crushed from the crazy depths they go to on a single breath hold
My buddies just started scuba diving and went to vortex springs on their second week? day? of class to train. I got them both a mug from yalls store with the vortex reaper sign on it. Love yalls videos even though I don't dive.
love all the constructive talk here from the hosts and the visitors. but i still don't get the 20m club which is not even a hundred feet. btw other dive channels say some sharks do care enough to be very curious. i also like when woody and gus once opened up the topic about the bcd being a possible source of air in an emergency. other sites say it should not even be mentioned for obvious reasons, last i checked there are no such thing as gag orders on honest discussions in the diving community.
Can Woody talk about disabled scuba diving? I’d love to learn more about it! Also Gus, it IS ok to say the word disabled. It’s not a bad word and impaired, handicapped, and “challenges” are euphemisms that can be offensive. It’s ok to say someone is disabled (unless they tell you to use something else)!
have you done the video where the Tiger shark tries to swallow a diver's head. It happened in Fiji in 2019 or 2018. It's a very short video but goes to baiting and diving with sharks for fun.
This is why I'm here. I have little knowledge of diving and would have just taken their video at face value, but you guys help clueless fools like me to learn what is accurate.
Have you ever read (or watched, I guess) Sphere? It would be interesting to see what you think Michael Crichton got right about being at depth in an underwater base.
A note on sea creatures ignoring you. Its most, but not all of them. A few that will screw with you, at least in California waters are: (1) Juvenile sea lions. They like to mock charge at you. They'll swim towards you at top speed, then veer away, at the last second. Kinda like one sided game of chicken, since a scuba diver is the next slowest thing in the water to a sea slug. (2) Harbor seals like picking on divers too. They may nibble on your fins, then swim away when you look ... or not. On night dives, on two different occasions, a harbor seal, twice my size, inserted himself (I'm pretty sure it was a bull) between me and what my light was illuminating, and actually nudged me out of the way, so he could get to his snack (a fish, I guess). Considering his size, he took some care not to injure me. (3) Moray eels that get habituated to divers, are like your dog at the dinner table. They come out to see what snacks you have to give them. (4) Garibaldi attack divers. Okay, its an 8 inch (20cm) long gold fish, and the males protect their nests, and will smack you in the forehead. (4a) In particular to my dive buddy Al, since its only happened to him. A small octopus (maybe ~1lb) attacked and wrapped around his forearm on dive once. I don't know what Al did to piss off this cephalopod.
Random question for you guys. If you are diving closed circuit, would you dive with a buddy that is on open circuit? Are there any special considerations for this "mixed team," or is it generally ill advised due to the differences in safety procedures and requisite knowledge for handling emergencies? Thanks!!
Sure...no problem. We just give the buddy a short brief regarding the rebreather and what to do in case of emergency and also what I would do in case they have an emergency (I.E. "Here is my octopus").
There are three modes of heat transfer: conduction, convection, and radiation. With conduction, energy moves from warm areas to cold areas when they are in physical contact with each other. Different materials conduct heat energy at different rates. Neoprene conducts heat slower than water partly due to the bubbles (air conducts heat at 1/20th the rate of water). The thicker the wetsuit the slower the movement of energy. Convection occurs with fluids in motion. When a cold fluid touches a warm surface heat moves into it (see conduction). As it warms up the temperature difference between the fluid and the warm surface decreases and heat transfer slows. When convection happens the now warmed fluid gets taken away along with its recently aquired heat and is replaced by more cold fluid and the rate of heat transfer increases again. Slowing the movement of water over your skin decreases compounding effect of convection. Wetsuits don't eliminate convection but they decrease it. I do not know the effects of wetsuits on radiation of heat, but I can't imagine they are great because they are typically black which means they tend to absorb and emmit infrared energy. Rather than reflect it inwardly back at you. Perhaps someone should develop a wetsuit with a foil lining that acts as a infrared reflector like an emergency blanket does.
Regarding the statement "Diving is for everyone": I just dove in Turks & Caicos in January with a man who is 90 years old. I kid you not. He has a dive scooter and he just scoots around while the rest of us suckers fin. The worst part of the dive trips for him is hauling himself around. The diving is still doable.
While I get your point, being physically handicapped such as missing a limb isn’t going to stop you from scuba diving, and there are courses to teach scuba diving to those people, I wouldn’t say that everyone can be a diver. There are a lot of counter indications to scuba diving. When you sign up for a class you must pass a medical examination first and the medic as well as yourself must sign a weaver, and present a medical certificate specifying that you are fit to undertake scuba diving. It depends of the agencies, but it’s the case with most of them. If you have a medical treatment/are under medication, if you have sinus problems, heart problems, high blood tension, are overweighted, etc. the medic isn’t supposed to give you a medical certificate and will specify each and every thing on the weaver, thus stopping you from undertaking scuba diving. But then a lot of medics, as well as clubs/shops just do t care and will let you take a scuba diving class as long as you pay them. You are supposed to take a medical examination and go through the whole process before each and every certification, but most of the time it doesn’t happen. Appart for CMAS related federations who take it very seriously. Taking a class to get certified with a CMAS related federations such as the Swiss (CMAS.ch) or the French scuba federations, being physically fit is a basic requirement. You must for example be able to swim at least 200 meters non-stop, dive on a breath to 15 meters, etc…
I'm sorry, but this is inaccurate. As mentioned during the video, Classified Diving makes it possible so people who can't swim 200 m non-stop for example can dive. I've seen the classes and the video, you can see people paralyzed from the neck down diving underwater. So although I agree with you in terms of being an autonomous diver you need to get medical clearance and be able to complete water skills before your training, there are options for people who can't complete those skills. But I do agree with you that there are some people that cannot be scuba divers, for example, if you suffer from seizures at random times, you should not be a scuba diver...even if you can swim 200 m non-stop and whatnot.
Being nosey and having a military diving hubby, whom started talking in his sleep, I never let on what was happening. He'd of been sent to the brig. Took months of listening to his dream talk to put it all together. He didn't dream in sequence of events. And he was extremely mean, a true Japanese man, in other words. Yes I had to walk behind him, 2 paces. I'd thought he was just a fast walker, until I kept demanding he slow up. He'd walk faster if I tried to catch up. Anyhoo, he was one of the first to use liquid air and survive. I do believe he married me to get to go to the back of the line. Single guys went first. He also ran chamber for the bends. Time frame 82 and 83, Roosey Roads, Puerto Rico. Great diving there. Huge lobsters without claws. Blue crap land migration in waves.
Do your own Top 5, guys! With goggles and flippers! On another note, keep in mind that in a lot of countries you actually pronounce Trimix as "treemix", as its more natural given local pronunciation etc. E.g. Polish divers mostly say it incorrectly, because it sounds "more Polish". Similarly we say "neetrox", not "Nitrox". Wouldn't be too hard on people for mispronouncing this :)
For neoprene westuits, they are actually a foam made by pushing nitrogen into rubber. The thickness of the wetsuit doesn't mean less water comes in. It means you have more volume of Nitrogen between you and the cold water. Nitrogen is bad heat conductor so it insulates you, slowing the rate at which your body heat spreads into the water. Wetsuit Thickness isn't a measure of "watertightness". It's the same principle as wearing a thick coat in winter, it traps more air in between you and the cold outside.
I hope I explained it clearly and did not forget important details.
Excellent comment! Thank you!
Like the loft in down-filled clothing.
Correct! And contrary to common belief, water between skin and wetsuit does not do any good. Water is never a thermal insulator, although trapped.
@@TomNelson1004 love our divetalk community. Such good info where we all learn from each other. Thanks is for this comment!
@@TomNelson1004 Yep. If you're sick of your tire pressure sensors going off in the winter time, have a shop put nitrogen in your tires instead of air.
With everything going on in the world today… it’s SO cathartic, relaxing, and JUST PLAIN FUN, to kick back and engage in some learning & laughter with you two wonderful fellas! From the bottom of my heart: Thank you, Woody & Gus!
You are so welcome!
This comment is so true! ❤️🙌🏻 I hope you all are doing well!
@@DIVETALKlove you guys! I can’t wait to do my first scuba dive!
I really liked that Gus gave five of his own facts at the end. I especially appreciated the accessibility PSA about diving being for everyone. Thank you both!
I like your top 5 better than their’s. True and entertaining especially for non-divers.
Woody...Gus...you two, especially your reactions, brighten any cloudy day I encounter...thank you both!!
You are the best Natasha!
Hands down, this is the most entertaining podcast (or whatever you call it) I've seen in a long time.
These two guys are priceless. Funny and witty. Perfect combo.
Keep up with the good work guys.
I love that episode of The Office!!! "If I can't scuba than what's this all been about?"
Found your channel recently and I've been OBSESSED! You guys are so interesting and informative.
I've always seen scuba diving as something terrifying - I've only done a 1 hour class in a pool - but you guys are so passionate about it and by the book, you've certainly left me more open to the idea in the future!
Welcome aboard!
Non-diver here. Love this channel and videos. Woody and Gus’s personalities complement each other very well. I also like how despite being expert in the area of diving, you guys remain humble and educational!
Honestly, hearing an experienced diver say scuba diving is for everyone is so heartening. I’m a 23-year-old cane user with chronic pain that limits what i can do outside of my home, so I long ago wrote off a lot of the experiences most people put on their bucket lists. Despite this, I’ve always had a love for the ocean (I’m a certified sailor!) and have been curious about scuba diving with my brother since he got certified three years ago. I’ve been falling even more in love with scuba diving since finding this channel, and I’m seriously considering looking into some classes now.
Thank you for sharing all of your knowledge, and for just generally being really great guys
Go make it happen!
Definitely do it. As long as you let your instructor know your limitations OUT of the water, they'll be able to accommodate you. Once you're IN the water, you won't know yourself - you'll be free! I've dived with someone who had terrible arthritic pain who said that their pain was significantly reduced whilst diving as there was less pressure on their joints while they were underwater. We carried their kit for them, got them kitted up in the water and helped out generally until they submerged. Once underwater they were an absolutely brilliant diver.
Your buddies will always be more than happy to help out however they can so don't be afraid to ask for help if you need it - we're all there to help each other enjoy the dive, whatever that takes, from carrying kit to holding someone's hand if they're nervous. Go for it - you won't regret it.😁
You also might look into a hookah set up which doesn’t require tanks or usually a BCD. Brownies Third Lung comes to kind.
Woody is a good man he teaches disabled people to dive. As a non diver I love this channel thanks guys. Going to S. Florida in a few months would love to make my first dive
This video was absolutely hilarious 😂. The way he said trimix sounds like a frog!! You guys did an excellent job at reacting to this video!
trrrmxx
The prefix has Latin and Greek origins, their way of pronouncing it would seem more accurate to its root. Out of curiosity, how would you pronounce triple? Same root.
Glad we got actual divers here , to help clear up in inconsistency in the video
After not diving for 9-10 years, it has been refreshing to find this channel.
It is great to be able to appreciate and re-imagine the underwater environment.
I received my Open Water Diver - Level 2 at around 2,650 feet.
Guys, it is a fact that the insulating properties of a neoprene suit depend on the quality of the polymer used and the number of air bubbles that the manufacturer can insert in a controllable manner in the polymer mass during fabrication. The thinner the bubbles and the more of them per cubic mm the better the insulation. The thicker the material more bubbles you have, and THIS is the reason a thicker material provides better insulation at the expense of increased bulk and reduced flexibility.
I couldn't begin to imagine the feeling of looking out over the ocean. Let alone DIVING into it. Absolutely mind boggling. I would love to one day.
I'm from Nebraska, where there are waves of sand in the great plains. I'm thrilled to have found your guys' page. I appreciate the time, and work you all put into these videos!
Oh I love Trimmix, they're my favorite breakfast cereal.
Diving checklist:
Oxygen ✅

Forgot the treemix. 😮
According to wiki, they may actually be right about the nitrogen bubbles in neoprene:
"Wetsuits are made of closed-cell foam neoprene, a synthetic rubber that contains small bubbles of nitrogen gas when made for use as wetsuit material (neoprene may also be manufactured without foaming for many other applications where insulating qualities are not important)."
pretty sure this was mentioned in the ''Encyclopedia of recreational diving'' I studied for DM'. I could have also read it on a manufacturer website though.
For production Nitrogen gets forced into the websuit to make it foam like.
Guess it does help with isolating the thing layer of water a little bit better BUT the main principle like Woody said is the water trapped on your body, as far as I understand it.
I am surprised that instructors laugh about someone else says, and I am even more surprised, if this is correct. But at the end of the day it's entertaining.
that is probably how neoprene is manufacture for the market so they need to use nitrogen to produce a foamy reaction in a liquid state where with air is not possible, but in general but the only impact of neoprene towards a diver is how thick the fabric as a suit is to give the diver a comfort against the cold water as barrier of insulation...no wetsuit company has ever claim to have a special nitrogen fabric as a feature for their suits because is irrelevant....basically neoprene is just a specific density foam that does contain trapped bubbles a a structure and use as a fabric for underwater suits.
Another great video, I love the humorous back and forth between you two. Keep these videos coming, I’ll watch all day!
About the Nitrogen thingy, the same principle applies to your regular thermos. Instead of having a single wall, thermos has double walls with cavity in between them. In cheap thermos, this cavity is simply an empty space filled with air. In high-end thermos, this cavity is vacuumed (of course not fully vacuumed). Air (or gas in general) is a poor heat conductor. Thus, the thermos can retain heat inside it (for hot drinks) or slow down the rate of heat transfer into the drink (for cold drinks)
Jacques Cousteau?? I thought it was "Jacqueeeees" lmao 🤣.....
Thanks for clairifying!! As a non-diver, I LOVE ur channel btw, I always thought the deeper u go down the more the weight of the water tries to crush u..so like somehow u always felt some pressure on ur body ..so crazy..not sure why I thought that. You guys explain things so well, it is absolutely not so scary sounding any more the more knowledge you guys flow! Thx guys!!
Ya'll are hilarious! Love how entertaining your videos are while also being educational and giving something back. Also, I can totally relate to being annoyed by those pesky remora... had one nibble on my ear.
Thanks so much!!
Hey guys, I've been waiting for the Top 5 or 10 things you should know before cave diving!!! And how to be a cave diver itself step by step. If that would happen, damn. This channel is gonna blow
The chemistry between you guys, the banter!!
Neoprene is manufactured by foaming the rubber with nitrogen gas, where the tiny enclosed and separated gas bubbles can also serve as insulation. Nitrogen gas is most commonly used for the foaming of Neoprene foam due to its inertness, flame resistance, and large range of processing temperatures.
i love you channel and have been here from the beginning. IMO your best content is when your bring on fellow divers and tell real stories. Sorensen, Young, etc those stories are riveting
still waiting for that delta P commercial diving video reaction boys
Paul, if you are referring to the Byford Dolphin tragedy, I am not sure much educational benefit can be gained for the wider sport diving community by visiting/presenting that video.
That said, having the GREATEST respect for - and wariness of - our ol' buddy Delta P is a must for anyone poking their heads underwater.
@@Coffeeguyzz no not the byford incident, a video called delta P its a diving safety video
I love that woody is always smiling, you can tell he loves this job
Great as always guys. And to Gus’s point about diving being for everyone. I’m 51 and just got certified this year after wanting to for many years. Anyone who wants to do it just do it. 👌
Congrats!
i think he was saying the bubbles keep you warm and not the material. the bubbles make an air barrier between your skin and the outside water, the same way insulation would work in a house. its not the material in the insulation that actually keeps the house warm, its the air it traps that makes the heat barrier.
I love how Gus and Woody reacted MORE to the random "20 metre club" throwaway comment than any of the top 5 diving facts bahahahaha.
In honour of Watchmojo, I present my own top 5 interesting Woody wish facts:
1. Prove octopuses are aliens.
2. Blow up a jetski. Bonus points if the jetski is pink.
3. Penetrate the Las Vegas NV hole.
4. Flashmob dive with Gus, Mike Young, Ed Sorenson and the Dive Talk fans.
5. Join the 20 metre club.
When Gus is overly sarcastic and Woody is practically speechless, you know you done goofed. The "trimix" comments were gold.
Have a great weekend guys! Another good video :-)
Those are my top 5 wants!! Those are pure gold!!! 🔥
The neoprene thing that was said is correct. I think its part of the factor and also that you warm the water also helps.
There is sooo much to learn about diving, in any capacity. I don’t think in the UK (where I live) the places they teach are very luscious in fish and coral varieties. However, from researching there seem to be decent diving schools. After watching your videos it’s been highlighted to me the paramount importance of finding reputable teachers!Who in turn teach the correct and safe ways to dive. So I don’t suppose it matters where you are taught so long as you are learning the correct skills/ techniques etc so you are safe and have a great time too! Thank you for your videos
The amount of inaccurate info on the internet is amazing...and frightening!It is very important that everyone does their own research and consult professionals in the field. On another note, "tree-mix" is even funnier than "Jacques Cousteau". Great video as usual.
I am afraid of getting in the water. But somehow I came across your channel and I have learned so much from you guys. I feel like maybe if I learn more it will help me overcome my fear. Thank you guys and I love how well you explain things especially for us non divers. Much love from AZ 🌵
Go snorkeling and freedive a little bit. When you can go 5-7 meters deep while equalizing, you gain confidence! Also, practise clearing your mask/clearing your snorkel and freedive without a mask. The more you learn in advance, the less the diving yourse is intimidating! And my final tip: Do static dry apnea exercises! That way you get accustomed to the feeling of not breathing, so that it will no longer cause anxiety. 2-3 minutes of static dry breathhold or more gives you confidence under water. During the owd course, you do things like taking out your regulator and putting it back in, which takes only a few seconds. If you never held your breath for a prolonged times tough, this exercise can be stressfull. But as somehone who can hold your breath for a while, this exercise can no longer freak you out! Other ideas that cause anxiety are: Loosing your regulator or failure of the device, out of air problems, not reaching your buddy quickly enough when this happens.... It all comes down to the fear of not beeing able to breathe. The longer you can hold your breath, the less scary this becomes.
Don't get irritated by the noise of the bubbles and the regulator, or the clumsyness with the bulky equipment. You will learn to use quickly. Have fun!
Doing our deep dive certification at Blue Grotto, my dive buddy afterwards said “It felt like microdosing” absolutely narc’ed on himself. (Scuba was collage PE credit)
@S M blue grotto is 100 feet I feel like it is a more less, but it’s right around 100, and the statues are probably 80 to 90. But we were multitasking, class of 20 or so, some where gettin open water, some rescue diving, we did a night dive same day at Devils den, that was 2016. Deep Diving through padi is only supposed to certify to 130 feet. We went to destin afterwards. I think the padi certification deep dives only require you go below 80, but don’t quote me on that lmao.
Honestly, Mojo's top five was just a glance of what SCUBA is. But Gus top five allows people to understand that it is easy to get into the hobby. For example, his response to people being disabled clears up a lot of fears people may have. I am not in the best of shape with my lungs and my bones. Looked into the training but what put me off was the fact I needed to have a doctors note granting me permission to train. Maybe in the future I will be able to learn how to dive and get more involved in the community, what Gus said really helped that.
+1 for not only pronouncing JC's name but also saying it with French accent, at least they got that one right lol
Soon as I heard the bit about nitrogen in the suit, I wondered if it was a misnomer. Then I looked into neoprene and apparently wetsuits are produced by bubbling nitrogen gas (essentially inert) through the neoprene (liquid) whilst it's curing, producing a foam. The nitrogen bubbles that are trapped provide additional insulation.
having use many brands and worked in a scuba shop ,about wetsuits, it does not matter what type of "air" is made of , it has no effect on the skin of the diver and actually I have not heard from any mayor wetsuit company to claim "air" bubbles features in their watsuits , they go by the elasticity and thickness and backing of their special neoprene and the insulation "warm rating " comes from the thickness of that neoprene ,where is located (torso, limbs,etc), and where will it be used (water temp) neoprene is a water proof membrane (some drysuits are made of it) , the water that gets inside a wet suit comes from the cuffs.neck,zipper ,etc and that water is what lubes the inside so it then that water between your skin and the suit lets the suit move and from to the body when it could not do it when it was all dry (the lining inside of the suit matters) ,the film of water touching your skin gets warm by heat transfer and the suit holds that inside heat depending of how well the insulated rating and or thickness the neoprene is (quality matters, thickness matters), sometimes my 5mm suits become too hot because of the water temp is too warm so I have to let water in to cool me or I began sweating underwater and they should fit tight like a seal skin so very little outside cold water trickles and moves inside or you will feel that cold water rushing and making you shiver at times, rash guards beats the purpose of a good seal , I know a tight suit feels too tight at the surface but under water it is preventing from the cold water to fill those creases with cold moving water... that`s my sales pitch and understanding of wetsuits and how they work from years selling and using them ,etc...yes they will compress over time and lose their thermal protection so get good quality ones that will last you for many years more than a cheap one. Drysuit are a complete different animal that also has cons and pros... I love wetsuit diving here in the cold waters of California ! just my two cents. cheers !
Great post. Thank you!
You can make neoprene into a smooth synthetic rubber. Wet suits are made of foamed neoprene. They don't use nitrogen particularly because it's a poor conductor of heat; it's obviously not far different to air. But it is unreactive in the foaming process and it does suffer less from diffusion out of the material over time because all the smaller molecules have already been taken out. As you say, the major factors in effectiveness are thickness, resistance to crush and control of flushing.
'Altitude' diving clearly does not all take place at 1000ft AMSL. He clearly means '.....is defined as...1000ft or above...'
'Trimmix', brilliant! One of those youtuber examples of someone reading off a page with no idea what it means.
But overall, surprisingly true. So good job by Mojo!
I like your top five, and in support I'd add that I started diving aged 56 and have loved it through the basics, twins and, as of last week, sidemount. New skills, new experiences, new places and new friends.
Yes nitrogen is a key component in wetsuits. They are made with what is called gas blown neoprene where they make nitrogen bubbles in the neoprene to give it insulating properties.
Neoprene for scuba has more but smaller bubbles than say neoprene for surfing because at depth the neoprenes would compress differently.
Exactly, and that's interesting to know, but would that be on your list of Top 5 Facts about Scuba Diving?
@@DIVETALK Definitely not. I am surprised that they didn't cover something like "Fact number 1. Water. When scuba diving, whether you are in the ocean, a lake, a swimming pool, in the USA or on the opposite side of the world, you will likely be scuba diving in water." Sure it might be a fact, but it isn't intriguing.
Titles matching content can be important. Such fun facts, interesting facts, horrifying facts, disgusting facts, etc. For "top 5 facts" the person putting it together should really bring their A game.
Keep the videos coming. We love them. 👍
Woody you remind me of leadership I absolutely trusted my life with when I was in the ARMY as a paratrooper. Love you guys God bless.
You are right about the wetsuits as far as the element of it with which you can interact . But the neoprene itself is 'air gapped' using nitrogen which is what creates the insulation value. Like how in a building, a 1' air gap is better r value than 7" of high dollar foam. It just uses trapped nitrogen gases to do the same thing.
I think a cooler top 5 would be
(Im a non-diver so this is stuff I find interesting)
1. Dive talk
2. Finding nemo
3. Woody drinking coffee
4. Cave diving
5. Taking gus dry caving
I like that you were both reacting for the first time
Your faces when the little mermaid started playing had me dying laughing🤣
Read the title "DIVERS REACT TO TOP 5 SCUBA DIVING FARTS" - and now I really want to see this video
I'm 45 I just started my diving journey. Between yall and my instructor I'm feeling more confident underwater
Sat here with a phobia of deep and open water but LOVING all of your videos 😂🖤
You guys make me want to Dive! Thank y’all. Don’t stop making videos
Gus your list was infinitely superior to Mojo's. Keep up the great and satisfying work guys!
Wouldn’t the water in the wet suit both get heated by the body and chilled by the water on the outside? I guess that equilibrium makes it not warm but not cold either?
Sitting in the parking lot before work cracking up. I don’t even dive and know better just from your vids 😂
I would be really interested in you guys talking more about diving with physical challenges, especially since Woody is trained for it.. if you had some clips to show us it would be even better! Thanks for all the great videos
If I can recommend a reaction video maybe to underwater diving construction it’s pretty crazy what those guys go through
warmth of neoprene is all about insulation, the thicker layer keep cold away from your body, just like jacket on surface. The fit of suit keeps water circulation to minimum but is not affected by thickness of neoprene rather than cut of it. As you dive deeper, the neoprene will compress and gets thinner and thinner so you get colder and lose plenty of suit buoyancy. And holding breath is another topic, you are not literally holding breath (like freediving) but definitely changing breathing pattern to affect your buoyancy and use your lungs for ascent and descend more than your bcd (CCR is exception because of counterlungs).
Love seeing the growth of your channel. Started watching at 15k.
Awesome! Thank you!
Trimmix! Your new favorite scuba cereal!!
!Dive talk!
My guys. Non diver here. .. but you guys help me have some sort of knowledge and respect of the craft.
Always appreciate your content :)
Some of my favorite things in life are Woody's hats and Gus' face palms.
11:58 unless you go nightdiving, for which a light is mandatory, then all the colors are so pretty, you can't even believe you're in the same place. Did a night dive in Croatia, in a small reef at 40m for my advanced open water training, there were so many colors, fish were sleeping in crevasses all around me and the largest number little crabs in spiky shells I've ever seen in one place. Man, I'll remember it till the day I die. A camera would have been better, but I didn't have one that could go to 40m.
Wait you mean you guys don’t carry around a wetsuit fill adaptor? I just top off my wetsuit before every dive with my nitrogen tank and then use it for the dive while I mouth blend my mix so I can have a continuous change of mix as I dive😜 another great video! Keep up the excellent work!! Also props to the community for coming together and sharing your knowledge with us! I know I appreciate all the information you all share with us as well!!
Diving is for everyone! That’s what I love about Scuba!
Thank you so much... not everyone has great holiday days and I know I did wonderful with the food, but all I could think of was diving and your videos 😆 I love you guys and went from being afraid vs real life fun to be be real and I soooo want to do it badly but I know I have MS and I I need real open water training.
Well I see Mike's Big Adventures already made the comment so I'll second or cosign with him. Your top 5 was definitely interesting, all 5 were not only things I didn't know but a few were the opposite of what I would have assumed, like not feeling the pressure, I mean I wouldn't think you're being crushed but definitely feel a difference. As usual great video fellas, I don't know how I started getting your videos but I'm glad I did
As stated in the video, pressure on the body, itself, has no appreciable effect whatsoever.
During the Predictive Studies IV project in 1975, we were at a storage depth of 1,200 feet, and made 'jumps' down to 1,600 feet.
No difference at all in physical impact.
Sinus issues or gas pockets under abscessed teeth can be a problem due to the compression of 'air' issues.
@@Coffeeguyzz Wow, now that's frigging deep brother, are you a Sat. Diver.I think what "tricked" my mind into thinking that way is forgetting or not really thinking that the body is like 70% liquid, because I know water and other liquids do not compress. As a Toolmaker who has spent a majority of my career making and building different custom one-off machines we will fill cavities with water trout before pressuring with compressed air( huh huh see what I did there?) to check for leaks.
The words mix and tri are adopted from the acient latin and Greek words mixtus and tria. Also the Latin scientific name of nitrogen is nitrogeneum and its original name coined in France is nitrogene. So you could say that the pronunciation of knee-trox and three-mix are correct 😬. We pronounce these mixes like this in italy.
I was in the Bahamas, I went snorkeling with barracuda, the operators threw our chicken bones left from lunch in and they didn’t bite a single person, I always get frustrated when they are blamed for “shark”attacks.
Great info..I always wondered how those free divers going for world record depths could hold their breath and not feel crushed from the crazy depths they go to on a single breath hold
That's true the wet suits are make with nitrogen to create the foam effect not regular air
My buddies just started scuba diving and went to vortex springs on their second week? day? of class to train. I got them both a mug from yalls store with the vortex reaper sign on it. Love yalls videos even though I don't dive.
Thank you! Vortex Springs is a cool site.
love all the constructive talk here from the hosts and the visitors. but i still don't get the 20m club which is not even a hundred feet. btw other dive channels say some sharks do care enough to be very curious. i also like when woody and gus once opened up the topic about the bcd being a possible source of air in an emergency. other sites say it should not even be mentioned for obvious reasons, last i checked there are no such thing as gag orders on honest discussions in the diving community.
Wait wait wait, I'd like to hear more about your opinions about Remoras, PLEASE!
On the funny top 5(or maybe top 10😆) I would add meeting aliens and talking to fish🤙🤣
I want a hit of that 🌳 tree mix. Yahoo!!!
So funny!!!
Can Woody talk about disabled scuba diving? I’d love to learn more about it! Also Gus, it IS ok to say the word disabled. It’s not a bad word and impaired, handicapped, and “challenges” are euphemisms that can be offensive. It’s ok to say someone is disabled (unless they tell you to use something else)!
What about if you have lupus, on blood thinner, along with about 7 other meds and a top implants because the meds messed my teeth up?
As long as the doctor says okay you are good to go!
Trim ix 😂😂😂😂 im definitely using that word now when im mixing gas in work. I cant cope 😂😂
I like when Gus and woody stops and puts their own input into the video very entertaining to hear their take and corrections.
Have you guys seen Weebubbie cave in Western Australia. Looks like some absolutely spectacular diving
Not yet!
have you done the video where the Tiger shark tries to swallow a diver's head. It happened in Fiji in 2019 or 2018. It's a very short video but goes to baiting and diving with sharks for fun.
Happy holidays to you both! We love u
This is why I'm here. I have little knowledge of diving and would have just taken their video at face value, but you guys help clueless fools like me to learn what is accurate.
Have you ever read (or watched, I guess) Sphere? It would be interesting to see what you think Michael Crichton got right about being at depth in an underwater base.
I have not
Yes nr 2 is correct.
The neopren contains gas bubbles of neopren. This is the insulation. The water entered is another story.
A note on sea creatures ignoring you. Its most, but not all of them. A few that will screw with you, at least in California waters are: (1) Juvenile sea lions. They like to mock charge at you. They'll swim towards you at top speed, then veer away, at the last second. Kinda like one sided game of chicken, since a scuba diver is the next slowest thing in the water to a sea slug. (2) Harbor seals like picking on divers too. They may nibble on your fins, then swim away when you look ... or not. On night dives, on two different occasions, a harbor seal, twice my size, inserted himself (I'm pretty sure it was a bull) between me and what my light was illuminating, and actually nudged me out of the way, so he could get to his snack (a fish, I guess). Considering his size, he took some care not to injure me. (3) Moray eels that get habituated to divers, are like your dog at the dinner table. They come out to see what snacks you have to give them. (4) Garibaldi attack divers. Okay, its an 8 inch (20cm) long gold fish, and the males protect their nests, and will smack you in the forehead. (4a) In particular to my dive buddy Al, since its only happened to him. A small octopus (maybe ~1lb) attacked and wrapped around his forearm on dive once. I don't know what Al did to piss off this cephalopod.
Well yes there are curious sea creatures but they are not dangerous, Seal pups playing with fins is cute not deadly
Another Great Episode! You make my day!!!! 😀
Random question for you guys. If you are diving closed circuit, would you dive with a buddy that is on open circuit? Are there any special considerations for this "mixed team," or is it generally ill advised due to the differences in safety procedures and requisite knowledge for handling emergencies? Thanks!!
Sure...no problem. We just give the buddy a short brief regarding the rebreather and what to do in case of emergency and also what I would do in case they have an emergency (I.E. "Here is my octopus").
@@DIVETALK Cool, thank you!
There are three modes of heat transfer: conduction, convection, and radiation. With conduction, energy moves from warm areas to cold areas when they are in physical contact with each other. Different materials conduct heat energy at different rates. Neoprene conducts heat slower than water partly due to the bubbles (air conducts heat at 1/20th the rate of water). The thicker the wetsuit the slower the movement of energy. Convection occurs with fluids in motion. When a cold fluid touches a warm surface heat moves into it (see conduction). As it warms up the temperature difference between the fluid and the warm surface decreases and heat transfer slows. When convection happens the now warmed fluid gets taken away along with its recently aquired heat and is replaced by more cold fluid and the rate of heat transfer increases again. Slowing the movement of water over your skin decreases compounding effect of convection. Wetsuits don't eliminate convection but they decrease it. I do not know the effects of wetsuits on radiation of heat, but I can't imagine they are great because they are typically black which means they tend to absorb and emmit infrared energy. Rather than reflect it inwardly back at you. Perhaps someone should develop a wetsuit with a foil lining that acts as a infrared reflector like an emergency blanket does.
Regarding the statement "Diving is for everyone": I just dove in Turks & Caicos in January with a man who is 90 years old. I kid you not. He has a dive scooter and he just scoots around while the rest of us suckers fin. The worst part of the dive trips for him is hauling himself around. The diving is still doable.
While I get your point, being physically handicapped such as missing a limb isn’t going to stop you from scuba diving, and there are courses to teach scuba diving to those people, I wouldn’t say that everyone can be a diver. There are a lot of counter indications to scuba diving. When you sign up for a class you must pass a medical examination first and the medic as well as yourself must sign a weaver, and present a medical certificate specifying that you are fit to undertake scuba diving. It depends of the agencies, but it’s the case with most of them. If you have a medical treatment/are under medication, if you have sinus problems, heart problems, high blood tension, are overweighted, etc. the medic isn’t supposed to give you a medical certificate and will specify each and every thing on the weaver, thus stopping you from undertaking scuba diving. But then a lot of medics, as well as clubs/shops just do t care and will let you take a scuba diving class as long as you pay them.
You are supposed to take a medical examination and go through the whole process before each and every certification, but most of the time it doesn’t happen. Appart for CMAS related federations who take it very seriously. Taking a class to get certified with a CMAS related federations such as the Swiss (CMAS.ch) or the French scuba federations, being physically fit is a basic requirement. You must for example be able to swim at least 200 meters non-stop, dive on a breath to 15 meters, etc…
I'm sorry, but this is inaccurate. As mentioned during the video, Classified Diving makes it possible so people who can't swim 200 m non-stop for example can dive. I've seen the classes and the video, you can see people paralyzed from the neck down diving underwater.
So although I agree with you in terms of being an autonomous diver you need to get medical clearance and be able to complete water skills before your training, there are options for people who can't complete those skills.
But I do agree with you that there are some people that cannot be scuba divers, for example, if you suffer from seizures at random times, you should not be a scuba diver...even if you can swim 200 m non-stop and whatnot.
Everybody knows it’s obviously the fart bubbles that keep you warm!
"Is there an application for that?"
😂😭🤣
Would love to hear you talk about trimmics a bit more in depth
This is the kind of video you watch in hour four of a TH-cam watching binge.
Being nosey and having a military diving hubby, whom started talking in his sleep, I never let on what was happening. He'd of been sent to the brig. Took months of listening to his dream talk to put it all together. He didn't dream in sequence of events. And he was extremely mean, a true Japanese man, in other words. Yes I had to walk behind him, 2 paces. I'd thought he was just a fast walker, until I kept demanding he slow up. He'd walk faster if I tried to catch up.
Anyhoo, he was one of the first to use liquid air and survive. I do believe he married me to get to go to the back of the line. Single guys went first. He also ran chamber for the bends. Time frame 82 and 83, Roosey Roads, Puerto Rico. Great diving there. Huge lobsters without claws. Blue crap land migration in waves.
Do your own Top 5, guys! With goggles and flippers!
On another note, keep in mind that in a lot of countries you actually pronounce Trimix as "treemix", as its more natural given local pronunciation etc. E.g. Polish divers mostly say it incorrectly, because it sounds "more Polish". Similarly we say "neetrox", not "Nitrox". Wouldn't be too hard on people for mispronouncing this :)
Maybe . When you’re under water, you fart nitrogen bubbles which are trapped under the neoprene and therefore keeps you warm. 😂😂😂😂😂😂
I can’t wait to get Tree-mix certified.
