Been diving for 50 years with bungee wings of death. Never had any issues. I have 45 and 60 pound wings in both single bladder and dual bladder configuration. One thing I do is to remove the bungees and reinstall them on only the side towards the diver. This still keeps the wing's shape but works alot like other internal bungee wings on the market. I have found that the diver is the main reason for any issues with equipment. I am Cave, Trimix, Cave CCR, and former instructor.
I've not been diving for a number of years now but looking at getting back into it. When I dove I dove with an OMS bungied double bladder. I loved it. I felt like it kept me more streamlined had redundancy and lots of lift. As far as the bungies squeezing out all the air I tend to believe one of the previous comments which stated the pressure of the bungies compared to the pressure of the water is insignificant. I felt like I was able to evacuate all the air to commence my dive hence was not overweighted but maybe I'm wrong about that. With respect to a run away inflator we only ever attached one inflator hose. The second hose was tied next to the backup inflator so it could be deployed if necessary. Thanks for the video. Before getting back into diving I will discuss these points with the local dive professionals in this area. I always want to be as safe as I can be.
Good video, however I disagree with some views. The extra drag can maybe be detected in the in water equivalent of a wind tunnel, personally I never noticed any extra in water drag. The bungee breaking and the wing "suddenly unfolding" is unrealistic. I only noticed a broken bungee after a dive, sometimes not even. Unless the bungee is floating around like a loop it's not such a snagging hazard as explained either. It's much easier to snag stage hoses than the wing bungees. I weigh myself properly regardless and can happily use both without issues. I actually liked the bungee wing because the air was not moving around when changing position. The potential danger is using an non bungee wing that is too large for the tank/s, as the wing can folks over and trap the air. This is a much more probable scenario than a broken bungee lopsiding a diver. Good video, safe diving👍
The fundamental issue with a lot of what is discuss is that some of it simply isn't actually backed up by physics! Question: at say, 30 m depth, what is the air pressure in your wing? The answer is 4 bar (abs) now 4 bar is 0.4 Newtons per square MILLIMETER of area. So an area the size of a postage stamp has a force acting on it of pretty much 25 kg! Now what effect do you think a couple of small bungess has? A typical bungee might have a rate of say 10 Newtons per cm of extension, apply that force over the area on which it acts (thousands of square mm per bungee) and you'll find the pressure exerted is tiny, in fact, compared to water pressure it is totally insignificant. This is really why bungee wings actually work at all. If the bungee pressure was in any way significant then they simply wouldn't work at all, because the air would not be able to fill the wing or it would simply fill one area only in exclusion..Luckily, because water is so dense, it always wins...... The only important reason, correctly and definitiively identified here :-) is that the reason NOT to have a bungee wing is simply to minimise snagging risk. If that is or is not important to you as a diver simply depends on the fact of if you dive in situations where snagging is in fact a significant possibility!
The bungees also cause air to be trapped,this a known fact. How each diver handles it,differs! Still a matter of your own choice knowing the pro’s and cons
I almost bought an OMS bungee wing decades ago because they really looked good and feel "technical". I ended up buying a dive-rite jr. wings which handles twins and one stage easily.
Now I sometime use O-shape Xdeep 55 lbs wing and sometime use U-shape DiveRite Classic wing 60lbs. But my first wing was OMS 100 lbs double bladder wing. With this wing I become TDI Adv.Trimix Diver and TDI Full cave diver. I never had a problem with this bangeed wing. Problem is not in equipment, problem is in skills. P.S. Now I am IANTD Trimix Expedition IT and IANTD Technical Cave IT.
For large guys like me that dive large size twin steel tanks we need all the lift we can get. 60 lbs can hardly keep me above the water and that's with no external weight. I weight 320 lb and am not obese. I am not a 3% BMI but that's the only way I can enjoy the sport. As far as bungie I inspect my regularly and I don't dive the extreme stuff and suggestions I will be open for ideas, as far as the smart comments about losing weight or get in shape I can still pass a military fitness test.
Very simply. I'm 249 lb full muscle fat 11% I'm using 15liter steal 300 bar tanks in twins plus some stages ( I need my muscle burn lot of oxygen), the answer is very simple :) Use a dry suit. it give you extra buoyancy. Also, XDEEP can make your special order extra large. Also, it is always harder to go down than up :)
@@ivoryjohnson4662 Not a bad one. I'm using Mares - much cheaper :) and much more resistant also it's neoprene one. Personally, before You buy one I highly recommend you to go and rent one to compare which one is better 4 you neoprene or membrane. You know 2k $ is a lot :) Personally, I use XR3, and my last one (6-year service over 700 dives was Aqualung). Also, calculate your buoyancy, and ballast u using. because on 54 lbs I'm taking 4 - 5 tanks :). Also what temperature of water you diving, what kind of undersuit u will be going is a factor to consider as well. It is hard for me to say anything because I don't know on what level you are, and also what kind of driving you do. At least please write down what equipment u have what tank's etc then base on mathematic i can tell you why you can not keep your buoyancy. Best regards.
@@michaeljohanowicz8697 I will keep you updated on my progress. I get a lifetime warranty at my dive sho including zippers seals yearly leak check with repairs only thing I got to buy are my zip seals .
Many divers are over weighted. They don't realize how dangerous it actually is. Buoyancy and having a balanced rig is one of the most important aspects of diving. Yet many dive agencies don't even tech this during basic training.
Clear; maybe an other argument agains bungees and the high volume of gas in it during diving, is more wing-gas-compensating dude to depth changes. If you move up or down, the (to much) gas expanded/compresses. Due to this, more compensation is needed (letting gas go of adding up) and this makes the diver less stable and more tuning with the oversized wing. (same as overweighted to much lead on the diver).
So when the wing is intact, the bungees will trap so much air, that you need to overweight yourself, but in case of a wing failure the bungees will squeeze all of the air out?? Maybe it's just me, but those two arguments contradict themselves.
Hello, I've been following this channel since 2018 and everything in the videos is spectacular. The explanations about different topics are very clear, there are several funny moments... this channel is absolutely brilliant and you helped me a lot with the majority of my curiosities about the world of scuba diving, thank you so much. Anyway, I would like to make a suggestion (if it's not a problem): I'm convinced that to add a really funny video on your channel, you could make a compilation of all of the moments where scuba divers get "caught" while peeing (my uncle relieved himself in a scuba diving session and that was hilarious), what do you think? I'd be so so happy to watch it, let me know, bye!

Hi, great video.
What is your way for buoyancy redundancy for wetsuit divers, since you dislike double bladder BCD ? Kind regards

I can exhaust all the air from my bungee wing. Maybe y’all just need a bungee wing training course rather than banning them.

Are bungies still a thing? Didn't Mr. Irving's rants end that concept?

A very "unique" idea Carlos..
I think people should manage the concept of probabilistic before spoke and review real cases
A perfectly weighted diver doesn't need much air in the wing.
Open up the Halcyon wing and show us.
Dislikes are from people who were told to buy the bungeed wings by dive store, who try to push it to everyone hoping that somebody will buy this pos 😁😁😁😁
The gas was trapped because the diver wasn't trained properly. There is 2 or more dump valves on a wing or jacket.
You're talking about moving into tight restrictions which most divers avoid. Talk is cheap. The Solution Is Simple, Safe, Effective.
Not really a cave a wreck diving fan then eh?
