- This is the Hydroid Aquabreather. Is it a rebreather? No. Is it SCUBA? Yes, but not as you've ever seen it before!
Without a doubt, this is the one scuba diving product for 2019 that has created the most buzz at DEMA Show 2019. Everyone is talking about it on the exhibit floor and at the cocktail parties. It is truly out there, so I had to take a closer look...
Here is the Hydroid Aquabreather's website if you want more information:
aquabreather.com/en/
The crowd for the pool demonstration was like nothing I'd ever seen at DEMA. People were either queuing up to watch a man drown, or they were eyeing the future of scuba diving.
I'm chatting with Egor from Hydroid about this wacky invention. As far as my opinion on it... you'll have to wait for me to go scuba diving with it and give it a review!
Part HALO, part NASA, part Darth Vader, the Hydroid Aquabreather uses proprietary canisters of a chemical blend that, once popped, gives off Oxygen. This is then cycled through your helmet and you can dive to a max. depth of 42m.
We have been at the DEMA Show for all four days and have shot a ton of video. There's plenty more product videos in this channel's future!
Dive safe, dive often!

WOW! This video has generated a lot of debate, which is what this channel is all about! Thanks for watching and subscribing!
I'm not going to answer all questions (as this was not a review video, more of a 'look what I found at DEMA' video) but the 4 most popular questions in the comments are:
1. How do I equalize my ears/clear the mask? (Exactly the same as a Full-face Scuba mask such as the OTS Guardian. It seals around your face like a FFM. There is a nose block, so pushing up against the bottom of the mask aids equalisation. You can clear the mask in the same way you clear a FFM.)
2. Do you need bailout? (Yes, absolutely, of course you would. You would need a seperate redundant gas source and a redundant mask.)
3. How much does it weigh? (The helmet is about 6lbs/2.7kg. It is supposedly neutrally buoyant in salt water.)
4. How much will it cost? (I have no idea! It's still at the working prototype stage. The cans are apparently going to run $25 each, and you need two per dive.)
Dive safe,
James
Hello James
i've checked there webiste, they state 4.5kg/10lbs instead of 2.7kg/6lbs.
if! the technology works, big if, then i have one crusial question, where are the counterlungs? since you cant breaht in a solid shape..
Not to be seen on the 3D model on the website, my best guess would be left and right side beneath the fancy white shapes (on the model you have there)
they could do a commercial version also, if those 2 small containers last so much, then a backpack full of it could be used for a helmet diver in a dry suit to stay underwater for a long time working or doing something 🤔
Congratulations you've effectively rebuilt an IDA-71
@@IberianCraftsman those canisters explode if water reacts with the contents.
@@alexpfilbert 🤷♂️ so what, it wont touch the water, so its not a problem
I've been using one of these for years. An earlier prototype meant for sports events. Depending on experience, 2 cans of the beer of your choice will last about 60 minutes. Baseball games tend to require more refills.
LOL that's fukd up.

The important part of all of this isn't if THIS particular product is good or bad...
Someday, these will be the shoulders that someone else stands on to create the greatest product ever!!
Instead of "attacking" all these new inventions and inventors with negativity, let's encourage them to build, create and invent! Fostering a supportive dive community and encouraging growth, not just in the Eco side of things, but everywhere!!
Yeah, if we could that, that would be great!
I really liked your point
Someone reverse-engineered Predator tech.
Yes . We always need new styles of equipment. Thank you so much.
Lots of questions to be sorted out but I like it hope it comes off for them 👍🏼
Very nice meeting you, look forward to linking up soon on some videos!!
I'll try it just to see the look on the lobsters faces when they think they're about to get grabbed by a Russian Mig pilot from the movie Top Gun.
When humans are not designing bombs and missiles you get this
Actually.... it is BECAUSE of humans designing for war, that you get this.
Almost every piece of technology we have today is from war designing.
However, prosperity is as you want, the USE of those things to better our lives and not kill each other.
I'm crying.. such depth and vision to your words.... lolz
Indeed, statism is a sick and dangerous religion.

@@magnus4g63 ok libertarian.
Bet this was invented by the Russian army and it has trickled down somehow (Russia is corrupt) and now they made a product out of the technology.
Very cool. Love Folks that are willing to push the envelope.
I remember divers that did not want to change to those fancy dangerous regulators 45 years ago.
Found it best to smile at them and say “Good for You”.
Be well and Thank You for the video.
I think I’ll let someone else be the Guinea pig for a while. If you want to find out how many ways things can go wrong, just put it in the hands of the general public.
It's not like pro divers don't already find imaginative ways to kill themselves taking unnecessary risk.
You can't design out "Stupid", Nature will always twiddle the knobs and pop out a better Idiot.
@Tim Rice
You’re saying stupid finds a way?

Considering that (to my knowledge) the chemicals that can do what they're talking about, do it in a reaction temperature of about 500 degrees and can explode on contact with seawater, it's an exceedingly dangerous idea.
😁 😁 😁
Average joe: so how much?
Hydroid: you can't afford it.
@CuriousCT was thinking about the same example
@CuriousCT lol think before you type out trash like that
max 4500 USD
There are no CCP “friends” , when they are gone , I’m fine with doing business with chinese ppl
@raw row no we wont do something like this!
Such a material as promoted in the cans reminds me of potassium superoxide, which is widely used by firefighters and mine rescue teams around the world in rebreathers. Interesting would be to know the exact reaction, because if it behaves like potassium superoxide and outputs more oxygen then the amount which originally was in the absorbed carbon dioxide, you will get an nearly pure oxygen atmosphere over time and would therefor be limited to six meters of depth while diving.
This looks awesome! 1 step closer to living underwater.
Can’t wait to hear more
Old technology repackaged, still it is a very compact and neat unit. Looking forward to how it is accepted by the dive industry. Cheers from Michael. Australia.
Super interesting and exciting to think about the future of possibilities.
Excellent invention with lots of potential but I do foresee some limitations and some possibly dangerous ones too BUT this is why I love a Kirby Morgan - Surface Supplied Air and Mixed Gas Dive Hat. I hope they get it fully tested and out on the market for pros and hobbyists alike. Great work guys and I wish you the best on this one.
those are depth limited tho
but kinda good for reef explorations in a group
Wow. new tech is awesome, keep going and don't stop.
Its quick and easily used at resorts etc....they probably will develop back mounted units for other uses
Wow...here comes darth breather 😆
Simply AMAZING. Claude
This looks a great product for us blue water cruisers..no need to carry an heavy compressor or using up storage for tanks..we wish them all the success and we've expressed an interest in purchasing a couple for the boat.
I love the idea. That said personally I would have used the new technology that absorbs co2 and creates O2 in a more main stream product to get buy in first then do a helmet if it's wanted. Hopefully the tech works as discribed and a new version of rebreathers comes to market over the next few years
I think if they get it right, they will change the game, but there are still a lot of kinks... Egor admitted that themselves when we were off camera.
the chemistry is not new and has established the working principle of ukrainian/ russina IDA rebreathers since 1964 at least.
@@DiversReady Yeah the biggest problem is probably regulating oxygen content. I bet one reason they're limiting the depth is that it'd put people into CNS oxtox if you go any deeper.
This would be ideal for spearfishing and reef exploration
Absolutely amazing 👏🏻👏🏻👏🏻🥂🍾
Great vid James, nice neutral and balanced approach. The device was certainly hotly debated at DEMA 2019!
As most divers at the show I have my reservations and questions about the device and technology. At the same time I feel as an industry we must be positive and supportive to new developments. We often have a knee-jerk reaction to ridicule anything new and different.
I'm curious to see how the product develops, and how diver safety is ensured, and especially how a training and support infrastructure is created alongside it. For me personally, I will still dive a 'normal' rebreather for now.
Looking forward to discussing it over a beer tonight at your place!
I haven’t seen anyone ridicule it, but there’s certainly some serious questions that need to be asked, such as how would you fill your BC and drysuit if you wear one? What about an emergency backup supply...how would that backup integrate into this system so that during a failure the diver still has air to breathe? Does this system completely seal out water at the neck, or is there an inner gasket to seal around the face like with a full face mask? And like a full face mask, will communications be able to be integrated into this system? How does a diver adjust for the pressure differences when descending and ascending?
Then there’s the question as to why NASA hasn’t picked up on such a system for our country’s Astronauts. Advanced scuba gear and space suits use very similar technologies. The rebreathers we use are similar to the system that provides Astronauts their oxygen when on space walks. And the brass zippers in our drysuits are also found in American space suits.(with the government, of course, paying 1000 times the price or more. So if this system is everything it’s being advertised as, why aren’t Astronauts using such a system for Space Walks???
That's old military technology , we used somethings similar in the tank when you have to cross the open water . For the emergency evacuation . They call " IP 5" insulated gas mask 5 . I'm talking about Russian military
Was going to say, it looks like Defence Industry tech...
It is also the same s the breathing technology in airline air masks
We used the same technology in the 1980's US Navy for fighting shipboard fires. That may be an easier market to start in if you can get it certified for fire fighting.
I think youre right. In Poland we used ATE-01, also for tank crew. Early version was a copy of IP5. But chemical componunds inside are dangerous during inproper use. So in late 80' constructor from Faser decide to replace chemical oxygen generator by small oxygen tank, and put just soda lime in absorber cannister.
Its hard to me, to belive that highly reactive chemicals are ok for low trained amateur diver.
@@spokojnyMamut It would probably be better with an oxygen tank, but it would have to be a separate tank to hold enough oxygen to be useful. One of the small portable oxygen tanks used for medical patients might work together with a CO2 scrubber.
Looks like a job for Thunderf00t.
Every now and then a new product comes along that changes the game I’m not a diver but we’ll see
WOOW...IT'S ABOUT TIME...WELL DONE DUDE!!
The best of luck
Crazy concept. I hope it catches on!
It just hit me! This in a way reminds me of an old style Navy OBA. Those were also canisters that created their own O2. We used them primary for emergency fire purposes and the canister could explode if they got water in them. Not that this product would do that (I hope). Best wishes to them but I need to see where the cost effectiveness lies with this i.e. annual service, replacement cans, what kind of warranty, what algorithms is the computer based on . . . Definitely going to follow this.
Russia was using the same technology to create emergency air supplies for their submarines. Sadly, it was one such canister that was dropped into the water in the only remaining compartment with living sailors after the Russian submarine KURSK had a torpedo detonate and sank during a Russian Naval exercise. Those canisters we’re keeping those remaining sailors alive while they were waiting for rescue when one was dropped in the water, causing a massive explosion that killed the remaining crew members. I hated the OBA’s. I always worried about sweat dropping down and getting into those canisters. Ironically, we were about the last NATO country Navy to actually STOP using that extremely dangerous technology.
Great observation, I remember having to put those on during GQ drills. Also reminds me of how "candles" were explained to to me on how oxygen was made on subs.
My first thought was, that can't work, but listening more, it does sound good.
I like your scenario at the dive centre.
As a rebreather diver those cartridges don't look large enough to do what they're saying. You have no control over PPO2 and as you go deeper you're just getting more O2 generated which is the opposite of what you want. If they'd said only 10 meters that would be be fine for an O2 rebreather. I wouldn't take it deeper without a N2 cylinder to make up the gas volume.
That is very exciting. Would be nice to have also in a boat emergency. Imagine you wake up on a sinking ship, grab this thing and at least you have some time to get off.
similar oxygen cannisters as used on subs for emergency air, good concept and as he has said its in the trial and testing phase..well done and best of luck
And if it was really feasible, why haven't experienced dive manufacturers have had this out yet, given it's really nothing more than rehash of what is already available technology wise? I think this is right next to the Scorkl...
@@mustang6599 it takes a lot of time for things like that to ahem, become actually avaliable, similar things do exist already but are for military use basically, its just that now someone is trying to make a commerically avaliable version, while im not an expect that seems to be the common consensus from people that have more experience with this kind of thing
@@randomfurrygirl548 But that's the thing, this is old technology. The basic underlying technology hasn't changed in years, all this manufacturer appears to be doing is adapting it to a "cool looking helmet" to make some money. REAL breakthrough would be significantly advancing the technology used to generate the breathable air within the helmet. That needs to come first before something like this can become a worthwhile technology.
@@mustang6599 i suppose so, but at the same time we really wont know for certain till we have all the details
@@botakbishop1441 Yup bingo, the main problem of this is that the chemical reaction produces too much oxygen, and it's going to create CNS oxygen toxicity, I guess the users will be happy it's a full face mask when they convulse though, no losing the regulator. The only way something like this works is by adding diluent, in this case probably a hypoxic diluent...
Awesome! Its about time.
I’m seventeen and have never thought about diving, but this is cool
Very much have my doubt on this.
1st, the weight/bouyancy: This helmet seems extremebly buoyant. You would need added weight to your bouyancy compensator or weight belt to counteract the added bouyancy. Unless you place actual counter weights on the helmet, good luck looking down. Even if this helmet concept was working, you would still need to carry a bottle, most likely on your back, to "inflate" your bouyancy compensator. You would also need a harness or another form of neck damn, to guarentee beyon any form of doubt, that your helmet does not "pop-off" at depth.
2nd, the partial pressure of O2: Pure Oxigen becoms toxic at depth. Most diving tables will limit a dive on 100% O2 to 25ft / 8 meters depth. At 42meters you would most likely suffer from an instant grand mal seizue and die.
I can see this helmet working as explain but only at arround 20 feet / 6 meters. At that depth, you could use a simple weight belt / wetsuit and not have to worry about O2 toxicity at high partial pressure. You would also need counter weight to the helmet.
Neat, but I wonder how much the canisters will cost? I'll be interested to see where they go with this and how safe etc it really is.
Love it great work
What a time to be alive
This system reminds me of the US Navy's Oxygen Breathing Apparatus (OBA), which is used in shipboard firefighting.
This is the equivalent of the Skully helmet for motorcycle riders. It is mostly the future of his creator only.
Hi, I'm Elfo
I was in DEMA show this year in Orlando Florida and nobody was talking about this!!! I think this product is good for skin divers.
Realy cool, I like it 👍🏼
A new challenger for the title "death mask".
I'd much prefer a small back/ chest / or side mount, and MUCH smaller helmet / mask.
zBones762 totally agree. Maybe a small chest mount.
Then build it.
Totally agree. if there are problems, how do you rectify them when they are inside a giant helmet?
Yeah I wear a Kirby Morgan for a living and this thing dwarfs it.
@@mrevildoer yea but your kirby is for serious work. This thing is for recreational.
Awesome Product! Reminds me a bit of the Predators Helmet
Amazing!
What forces the air through the chemicals?
I've seen the "internal pressure cylinder" in some blow up schematics from their website. It is tiny. And according to the show and tell, you can pump that up with a "hand pump".
If THAT is your emergency supply... and your buoyancy adjustment source, AND the depth / pressure adjust... maybe I am missing something critical but I don't see how that would work.
Plus, with no BCD, ALL of your positive buoyancy would be in your head.
great points!
BCD is clearly the key point to this. divers too heavily plumbed will get in a lot of trouble without BCD
Interesting, wonder how bouyancy control is dealt with?
yap, that is what i am thinking too. but i am also interested in the price, but i got a feel it will be in the range of the RB set! lol
Lungs
He's wearing a typical weight belt. If the helmet is buoyant it should act like a BCD.
Buoyancy control is really related to the rest of the stuff most divers strap to themselves.
@@christopherpeninger324 Yeah, great on the neck...
The “burp” at 2:26 is priceless.

This is so cool but how can i clear my mask if it were to flood and equalize my ears with it
I second this comment
👍👍👍😜🏴🦄😁🤞✌️
You have a faq on their site. Seems fairly easy
Carries a small co2 or nos cartridge to purge but they didn’t discuss it.
@@superyamagucci hopefully not CO2, that's what makes the mask fog in the first place, LOL
So we wont be seeing this product for a long time is what I am hearing. lol
Because it's dumb tech
pretty nifty should come in handy for those on site procurement missions out at the longbeach harbor.
Right now im happy to be a freediver!!!
No kidding haha
Haha Yup
I imagine free diving your lungs are in excellent shape. I would love to do this but i cant hold my breathe for even 1 minute and dont know what to do to make it longer.
Smart but scary at the same time seems unsafe but I won’t know until I try it out
It's filled with KO2 which will explode if it it gets wet. Really want to try wearing that on your head?
Wow ... amazing! i like novelties!
Wow! This is a game changer.
i would like it more if it was a streamline backpack with a wristwatch display
so you can choose your own goggles and don't have that huge glob on your head
totally also they could add way bigger solution tanks in a backpack so you last way longer underwater... they focused too much in making it a "helmet only" thing, they could do more reasonable models in the future from customers feedback though.
Yeah, the idea to put that into a helmet is horrible from a product design perspective.
It needs a gas supply to increase the gas density in the item as depth increases otherwise it will fill up with water
It might be a wet helmet with a mouth pieche, not a commercial divers helmet that is full of gas.
@@suvarbm what the hell are you talking about? A wet helmet? There is no such animal.
When a seagull eats an alka selzer water can not enter the cavity. Same principle
@@1STGeneral more complete nonsense - alka seltzers and seagulls ffs.
@@Berkcam goole, aquadyne dmc 5 or kmb 28 helmet shell, there is a number of so called wet helmets that we have used in the industr the last 40 years.
Will be interesting to see what comes of it!!
This is very revolutionary. I would like to use one.
How long have you been diving and at what level?
In the US Navy we used what we called an OBA (Oxygen Breathing Apparatus) for fire fighting. It had a canister that acted as a scrubber and O2 generator. This hat seems like it uses similar tech.
*Edit*
I just visited the web site and one issue I have with this mask is the ability to clear it if it becomes flooded. The web site states "If the apparatus is taken off completely when under water, the mask will be cleaned by forced gas supply from the cylinder." How much gas could this cylinder possibly hold? Can it clear the mask at max depth? How many times?
Lol just wait until the KO2 in those canisters react with water, kaboom.
I think a major issue will be the depleted chemical canisters. The US Navy has used similar technology as well. There could be problems with contact with water as well. However, there may be some practical applications for further development.
Most impressive video thank you for sharing that. Hope it’s all true!!
It’s a cool concept, but dear god is it bulky. It needs to be a backpack type thing with hoses to a mask. Either that or just slim it down some.
i think it should be a backpack, too
Absolutely right.
Why a Helm and not a slim streamline bcd design connected to my full face mask?
It just looks way to clumsy for a headware!
Idea is great but not as a helmet!
so true
@@pgarland2 id be more worried about the drag of that and the stresses on the neck for the weight and drag combined in current....
Have you seen Aa Kirby Morgan 37? We dive with em all the time in the oilfields and yes they are clumsy, on the surface, once underwater....its not.
wow I want one for sure
I love that hydroid mask. No lugging heave tanks. Us old guys can catch a break!
To dive safely, you still need your back-up gas supply, so you will have to carry some sort of come-home bottle.
This thing has very limited applications, primarily military. It is enormously expensive - $ 25 a can means a 1 hour dive costs $50.
At the end of which you have 2 cans of toxic chemical waste. I'd love to try it out, but I can't think of any way I could use it.
This can't be taken to any significant depth. There is no sign of any nitrogen source, so as you dive and your body absorbs nitrogen into your tissues, the recirculating gas will be depleted of nitrogen, the breathing gas will shift toward higher pO2, and the user will convulse and die. For god's sake, people, this is diving physiology 101.
Edit- okay, they do have a small air cylinder for volume makeup, I retract my pO2 concern. I assume they have some means of modulating the rate of O2 generation or to waste excess production, in order to control pO2. Flooding the canisters would still be a catastrophic life-threatening failure.
Same concerns I have. But the volume makeup cylinder...what if it fails?
I’m curious about equalizing. How would you be able to do that with this helmet?
Probably the same with any old mask: breath out through your nose. But the fact this thing would be around the entire head poses an entirely different problem... especially since we're talking about different levels of pressure when the diver descends... I read about using yawn, swallow and jaw thrust techniques for diving helmets... maybe it's just the same thing...
But one thing for sure: you wouldn't get me risking my life with one of those things on. Much rather just grab a regulator and be done with it, sure I have to do the PADI course: but it's probably a hell of a lot cheaper and easier to get approval to dive with. Who knows how long it would take to learn the safety precautions just for this helmet alone.
That would revolutionize structure fire fighting as well
Great innovation so much better then standard equipment
How do you equalize? How do you de-fog the mask? What happens when water gets into the loop?
If water gets into the loop, it is very likely to explode.
Wha a load of bollox
being a fairly new diver i have to ask how do i inflate my BCD where is my Alt incase of buddy air fail while on a dive how do i make equal pressure while diving down ? all of there are fundamemtals of diving yes i know my spelling is not the best lol
John Connelly I’m guessing most dive shop would it’s say no
Its a full helmet so it would be equalizing as you breathe. Your alternative air or bcd inflation would be by pony i should think.
@@panzerswineflu I'm pretty sure it will have a bed to push your nose into, just like a commercial helmet does. That will help out to equalize.
The bc and buddy could easily be provided by a redundant air and separate inflation system. To be honest even a recreational diver should carry a back up air supply to cover you for a safe accent.
Amazing tech, but nothing can beat an hour long dive in warm water with a good buddy using regular gear in a great location, oh and "decompression" beers in the sun afterwards. :-)
Ever since Jacques-Yves Cousteau invented (or maybe more correctly improved?) the regulator in the 40s', maybe its now time to embrace a more robust and user friendly gadget! But I think the normal regulator has the clear advantage of easy sharing among divers in case one of them is malfunctioned. This gives a peace-of-mind for divers. I can't see how this device can be shared among divers in case of emergency!
I'll save my money till the Batman breather comes out.
Batbreather*
If you dive for a living it would pay for itself !
@@jjdeepsea The cartridges are $1700 for 60 minutes.
@@Frindleeguy Wow I will keep my scuba tanks!
How does it regulate pressure as it increases with depth?
Also, does the apparatus chemistry react to the introduction of seawater?
It has a 200 bar mini - cylinder (400 ml )containing 40 litres, which is available for depth compensation or to flush the hat if it floods.
The mini-cyl is pumped with a hand pump (oil-free).
They put a lot of effort into keeping water & the chemicals apart.
It's worth visiting their website.
This seems to be Russian military development being marketed to the west, very interesting.
Looks like I can use it when I'm painting in an enclosed space.
they need to have quick cans that is either intergraded on your vest of have a belt or even side leg bags that can hold extra cans! Awesome product for the future
This could be a real deal ifbit really works. Couple of years ago there was a similar product that was supposed to filter out oxygen out of the water but never was mass produced due to obvious reasons like o2 concentration in the water far to low for breathing
This doesn't appear to be pulled oxygen from water, but those cans are a combination of CO2 scrubber, and a Oxygen generator, maybe based on the technology used in airplanes in the past.
I've gone diving over 30 times and loved it more each time.. this seems interesting but i would really like to see it demonstrated in the Ocean. I wouldn't buy or try Generation 1 that's for sure...
Lauren I have something you can breathe through.💜
This is improved military tech.
Here's a video demonstrating the Soviet IP-5 rebreather, which uses the same concept. Note the potential hazards discussed in this video (underwater fire, explosion, etc).
th-cam.com/video/CowjpZDtNlE/w-d-xo.html
That being said, it's not impossible to make this system safe. But I definitely wouldn't trust Gen 1.
This defies the physics of diving. It's a death trap not really an innovation. I suspect this guy isn't a diver himself. Diving isn't just about making something waterproof and go diving
I thought I saw you at DEMA. Our team had a big discussion on this helmet.
It may also be used in space.
I just seen the thumbnail and immediately chanted ..... "Glory to Glorzo!"
How much heat is generated during use? I used chemical rebreather in the military for firefighting and the canisters got hot enough to burn you.
sea water should cool them easily
It looks to be based on the same old tech. that we have had on Navy vessels for a whole lot of years.
Good question! I think the reaction proceeds at, like, 500 - 600 degrees Potassium superoxide. Seawater might be enough to cool it but the cann8ster is in the helmet with your head! And, if it comes into direct contact with the water, it's very likely to explode.
@@angelakristin2927 it would be much safer in a backpack style, like the soviet IDA-71, also cooling systems are really advanced this days, you could use a mini electric pump to circulate cold sea water, although i think the best solution is a heat sink just welded to the deposit and the sea water would cool it.
@@IberianCraftsman I think you're right that set up would cool the thing and the back pack idea is definitely better. I read about someone who used the stuff in a backpack to climb Mt. Everest and it sounded like it worked very well. But it's the explosive reaction you can expect if seawater gets to it, that makes it unacceptable. I think the IDA-71 was intended to be used with potassium hydroxide although I get the impression some have used it with potassium superoxide -- I dunno. The Soviets also used the stuff in their space program.
This appears to be the same principle as the old US Navy Oxygen Breathing Apparatus (OBA) used in fire fighting prior to the Scott Air Packs.
Very good
Be interesting to try out.
Interesting, but still many questions to answer :
- what is the helmet is getting flooded (if I'm not mistaken : water + hydroxide = kaboom ! or at least something uunpleasant)
- how to check/regulate PpO2
Time will tell I hope.
Or share air with a buddy when someone runs out or equipment malfunctions.
Did the guy actually says 60 minutes???? I can't imagine how this would work...
@dethrophes so it seems but... You need around two tanks to stay underwater for an hour or more (as far as I know). So I can't imagine how they say it last for an hour with such a small recipient.
How does the dive time chart with depth and mix?
@@panzerswineflu INdeed, but my point is... For a regular diver to be underwater for n hour, needs a heavy tank and control his breathing. Here, they are saying that you can be underwater for around an hour with 2 soda cans (considering the sizes)???
@@hnavia Because (as they claim) the air is not expelled it's scrubbed and re-used. If you had a 100% efficient system then you would only need a couple of lungs worth of air at pressure and it would last forever (obviously not taking onto account issues around deco etc.)
@dethrophes the size of those used in aeroplanes is very similar.
However these guys must have really pushed the boundaries as the ones in aeroplanes are only designed to realease oxygen for approximately 2 mins.
Ive recycled enough of them to know.
They are activated by moisture as well
Nice concept. But for sure it still has a long way to go...
Very interesting! But I don’t get it, how about buoyancy? Inflating a DSMB? Etc. I feel like it’s a product with great potential, but maybe adding a light vest, with some features we already have would be better, IDK 🤷♂️
I'll stick to my KMART mask and Snorkel
