I worked in a Scuba shop in high school in Jersey City Nj USA. This was 1973-4. A man in the town invented and produced an item called. “Snork-Air”. It is exactly like this except instead of a normal built in regulator , The mouthpiece had a small lever in it. Instead of giving air based on inhalation, you actuated the air flow by pushing up with your tongue! When you had a breath you let off the lever with your tongue and a spring would return the lever to the No flow position. It did not sell well and was discontinued long before I worked there but the inventor was a customer when I filled his tanks so I got to try it. I can not find anything on the Internet about it and I forgot the man’s name but I tried it in the pool and it worked fine.
I dive with a SpareAir and love it. I sat on the bottom at about 40 feet and took more than 20 breaths before I got bored and just went back to my normal reg. I am sure it would be good for a safe ascent from my normal dive depth of 70-90 feet as long as I breathe normally during the emergency.
I agree with Garbossa, Spooks and others that these cylinders should not be used except by qualified SCUBA divers, and even then only as an emergency bail-out in a low-air situation. Although no diver worth his salt should get into a low-air situation in the first place. There is the danger of lung expansion injury (aka "burst lung") on the way up and even the danger of ruptured eardrums on the way down without proper training. This half-baked discussion of SCUBA techniques seems to be getting more and more popular on UA-cam and should be avoided. Get proper, certified training and stay within your limits. I've worked as a DM in the Med, Indian Ocean and Red Sea and seen enough "qualified" divers doing stupid/dangerous things. Diving is a wonderful, safe pastime but only if you follow the rules: ALL of them.
I agree anyone using these should get scuba training first. But I see nothing wrong with a certified diver using these for shallow dives (down to 10m as it says on the instructions for the tank). There is no bigger chance of lung expansion with these tanks than with a regular scuba tank. The physics is the same. And the chance of getting the bends is slim to none as at 10 min you don't have time to get enough nitrogen in the blood to make any issue.
We used to carry tanks like that on our vests when we were doing drug interdiction in helicopters out over the ocean (probably only about a third the size of that one you tested). We were told we could only count on two or three good breaths (and after that if you were still in the sinking helicopter, it probably didn't matter anyway). I always wondered how long they would have really worked.
@@ralphholiman7401 I mean, items that would be super expensive or a pain to use I get, but that wouldn't really seem like one. I'd wanna go play with it, just outta curiosity lol
@@samueldeter9735 , I thought the same thing. But, we were working out if a remote base in another country, and, we didn't even have a way to refill them.
We had tanks like that on our vests when flying helicopters over water, to be used while you were escaping a sinking helicopter. We got like a minute long lecture on how to use them. My confidence was never super high on what would happen if I ever actually had to use the thing.
@@ralphholiman7401 For work I had to do the helo ditch drill. We were given the same kit as you describe and were seated in a mock up of a chopper on a rig over a swimming pool. The chopper "crashed" into the water and turned upside down, then we all had to make our way out with the aid of a couple of instructors in scuba gear. Everyone though it was a lot of fun. Then the instructor said, "That was in daylight over a warm swimming pool. You guys will be going out to the rig at night in rough conditions over a freezing sea. Good luck!"
At 10 meters you will use double, at 20 meters triple, at 30 meters quadruple so on so forth. So using 25 liters a minute this tank lasts 6 minutes at the surface but only 3 minutes at 10 meters deep
"hot air expands a bit" Well, it actually expands A LOT! Thats why diveshops with a compressor often have an heat exchanger (cooler) around the ducts that exit the compressor. It easily brings 20 bar of additional pressure when a filled divetank is left to go back to room temperature.
I think of this as an accessory to freediving or spear fishing, when you are laying at the bottom of 6-10 meters, you can use this to fill up your lungs. Which might make it last for longer as you are laying still. Still about 5-7 minutes is probably the max because of the pressure underwater making it half capacity from what it would be at the surface
1. This thing creates bubbles, which means the noise is going to scare away fish. So it's useless for spearfishing. 2. The second you breathe from this you are no longer freediving, but scuba diving. And since scuba tables really aren't developed for multiple short fives with fast ascend- and desend-rates and few breaths, they are basically useless. Which means you are just gambling with your safety as you wont know what actually happens in your body. There is no point in accepting so much risk for extended dive time. Just become a better freediver or vice versa switch to scuba if you are unhappy with your dive times.
So I used to be an avid swimmer prior to having heart surgery (was born with a heart condition that got missed for 20 years and almost died...fun times lol) so honestly this would be something I would use because it's lightweight and simple to use. I've seen variations that have a carrying case and a hose attached, so would probably do that then one where you're basically holding it out of your mouth. And the only thing I could think would be to stay about 8-10 feet for a while, maybe a little deeper. But not something where you couldn't easily get to the surface. But I'll take 8-10 feet for detached snuba, essentially, than nothing. I'm probably never going full on scuba diving again with the complications I've had since surgery
@@IVfluids1 Every compressor is internally lubricated with special compressor oil. This oil, which is quite nasty, has to be fitered out. Real diving compressors like Bauer have huge filters to clean the air. This one doesn't because it is a cheap Chinesium paintball compressor. Not intended for breathing.
It is correct that you should not use any compressor to fill tanks with breathing air. But that specific compressor I use in the video is made for breathing air. It has a carbon filter that filters out moist and impurities. That filter is changed after each time you fill a scuba tank.
I mean 5 or whatever minutes isn't bad for a small thing like that, it's a genius invention basically. But it would have been better if it had a wire so u can see how much air u have left instead of just taking it out of ur mouth each time
While watching the video I went to Amazon very excited to order one of these and purchased one!! 😀 Saw the part of the video where if you surface incorrectly your lungs could explode. 😲😧 Amazon: canceled order because THAT would be me! 😩
The reason Christian says not to put oil in the threads, is because if you were to use Oxygen in the cylinder it would significantly increase the risk of fire.
I see this as a good emergency back up for spearfishing. If you or your buddy get caught in line of hung up under a ledge...could buy you 7 minutes to get free 🤔
@@marinekong235 I suppose whoever runs a submarine will not rely on cheap Chinese emergency tanks. And escaping from a military submarine is only really possible if its in shallow water anyways. (via the torpedo tubes)
@@vast634 wrong - submarine technology has improved - up to 600 feet depth - need to move on from WWII. US/UK esp UK tech is going down the drain literally
I can see some uses for this. Boat maitainence would be a good one. Spearfishing or snorkeling would be another. Any situation in which you would need a bit of air in short intervals rather than one long dive. I do have some concerns about accessibility though. Compared to a full set of SCUBA gear that costs thousands of dollars, most people who don't have proper certification wouldn't bother making that type of investment. Something like this that costs only a few hundred dollars isn't the same financial barrier to entry which leaves the door wide open to people who have zero experience or training in dive safety.
Boat maintenance / spearfishing / snorkelling - ONLY if you are scuba trained, If not get ready for a big medical bill when treatment is needed for related illnesses from using compressed air at depth.
All depends on the depth where it used, your lung capacity and breathing rate, volume of cylinder, pressure in the cylinder, calmness of mind / panic state - in other words it differs each time you use it.
IDK about you, but I would rather go with a standard aluminum 80 for a pony lol. To be fair though, they are used as a spare gas source for aquarium cleaning and such. No deeper than 2meters.
That’s a cool little gimmick:) You mentioned that you can hold your breath in static apnea for 10 minutes. Would you be willing to make a video explaining how to learn to hold your breath longer, without damaging your brain? I’m really fascinated with free diving, but can only hold my breath for four minutes laying face down in the water. Three, when I’m moving.
Take a freediving class. But really, *very* few people can do a ten-minute static. Some years back I watched as a new Canadian national record for static apnea was set at 7 minutes and 28 seconds. That was a national record! Your 4 minute static and 3 minutes active is awfully good. But a freediving class would be the best way to learn to improve.
@@danielschechter8130 I've mad 6 and a halfish but by grandma thought I drowned cuz I did it floating face down.

Nice compressor. Does it have oil and water removing replaceable filters somewhere? It just looks like the same compressor from aliexpress without any mods.
So we are not going to talk about lung over expansion injury from holding your breath while using compressed air? And how it can happen in shallow water?
You don’t get over expansion injury from holding your breath while using compressed air. The regulator will do its magic. You get the problem if you hold your breath while you ascent to the surface after breathing in compressed air in the deep.
I was thinking of getting something like this. Not for diving but rather as an emergency item to keep in my car. For in case I accidentally take a plunge into water and need to get out. Any thoughts on this as a use case
Did you say you can hold your breath for 9 minutes? When I was a kid I trained and got up to 3:45 and i was a smoker. I thought i was doing good. I think once i might had made 4 minutes. I also swam the length of olympic pool and back underwater but 9 minutes is amazing.
I think those compressors are generally not recommended to fill up air tanks that are intended for breathing. Especially without the additional filters. But im not a scuba diver and only use my compressor to fill up the air rifle. So im always keen to hear about your opinion.
@@Christian_Wedoy are the filters sufficient to emit class E quality air from a hot electric pump that is lubricated with oil? are the filters purchasable and replaceable? does it have a moisture trap?
You usually get a free flow problem after some minutes when diving in close to freezing water because the compressed air lowers the temperature when it expands. If you use this as a spare air source it will not freeze before after you start using it, and probably not before it is empty anyways. If you want a spare air supply, I recommend the Spare Air that is made for that.
@@Christian_Wedoy that’s what I was thinking. I had one free flow on me after 20 min in 6°C water. Luckily I was only 15 metres down. I had a friend of mine whose reg froze 30 metres down in Lake Ontario. He had a little longer swim up. I’ve just started looking to get spare air, or another small bottle.
Btw. Nice name. I did a show in Romania in 2018 and they did not know how to pronounce my name when they were promoting the show, so instead of Wedoy they called me Woody in the Radio commercial. Since then I have been known as Woody in Romania, Serbia and my girlfriends whole family just calls me Woody.
@@Christian_Wedoy Well, if it's Christian Wedoy using it here of course it's safer, but yeahhh, big bulky thing in front for a normal person would be hard to see, and react quick enough.
@@Christian_Wedoy Yes but, these reserve tanks are just easier to get as they come along cheaply. People buy these things without getting the proper knowledge.
I have an invention along this line that nobody has even heard about or considered that I know of, but I’m not sure who to take the idea to without getting screwed.
They can be fun to use for short dives to inspect your boat, dive down to look at something or for fun. But you should get scuba training before using it.
These should never be used or relied upon to begin with and you don't 'decompress' as you descend either, when you descend you're on gasing nitrogen not off gasing. This tiny 2L tank would barely be enough for a 'safety stop' yet alone any extended decompression stop
Can I use _any_ compressor. For example, I have two air compressors for car tires. I understand that there might be a bad smell or taste, but will the air be safe and useable?
I really want this but im terrified im going to rubture or burst my lungs also how deep can you go without bursting your lungs when holding your breath when coming back up
if you take a breath at the surfice you do not need to worry about lung expansion. Lung expansion only happens durring diving when you breath compressed air at a depth and accend from that depth. the expanding air will cause lung damage.
@@Eflgoat If you exhale while ascending your lungs will not rupture or expand. meaning you can go as deep as you want without worrying about lung expansion
@@Seaweed-mw1rr i will explain this more clear for you because that is not what i meant so how deep can i get when i have inhaled and im coming back up to the surface without rupturing my lungs
It's a simple maths and physics : 200Bar x 2L = 400L. Average lungs capacity (men-5-5.5L, women 3.5L), Average inhale qty - 12-14/min so, if we would take the lowest capacity 5L x 13 times/min = 65L/min, 400L : 65L/min = 6m15s :)
Hey so I'm looking at this as something to get for fun and get more used to being underwater before I take actual SCUBA certification classes. I don't want to spend a fortune on this so I'm wondering if there's a cheaper way to fill it with air? Would a bike pump work? I'm really new to this and don't really know anything about air compression or anything like that.
Take the class first. At least then you’ll be aware of all the dangers of breathing compressed air. You’ll have more than enough opportunity to “get more used to being underwater” in your course. While your at it, ask your instructor what they think of this product. I doubt it will be favourable…
I need to ask you some thing. So i Wonder if the plass you ar diving is calld Pirbadet. Cus i i am from Norway and it is not so common to se a Norwegians UA-cam whit over 1 mill subs.
The main things are: NEVER scuba dive without appropriate training, NEVER scuba dive solo without special training, NEVER fill your tank from unknown sources especially from the compressor not intended to be used for breathing air and NEVER EVER hold your breath when the regulator is out of your mouth.
no way you could get 15 minutes out of that Tank.I started using those tanks in 1982.He got 10 min in a pool and kept taking it out of his mouth Take one down to 40 or 50 feet in the ocean in see how long they last.When they first came out is was designed to get you to the service at 100 feet in the best conditions.If you run out of air at 100 feet it wont be perfect conditions and I doubt you will make it to the surface with out doing a free ascent from about 30 feet
Diving on compressed air without proper training is just not a good idea. If anyone is interested in using this it would be a good idea to get trained in scuba
@@Christian_Wedoy My comment was for folks that have not had any training on open circuit. This is sold as a fun recreational toy. Any trained diver would agree that is a bad idea
The reason why this happens is because the air in a scuba tank is compressed. As you go deeper, the pressure from the water compacts the air in your tank and your lungs and makes it more dense. If you breath the compressed air to fill your lungs at a lower depth and start to go up, the air in your lungs will expand because of the lower pressure. If you hold your breath, the air has no place to go as it is expanding and then pops your lungs like a balloon. This is why you never hold your breath when breathing from compressed air. You can still hold your breath when freediving or breathing from regular surface air because it can only compact as you go deeper and expand back to the original state when you surface.
Can’t wait for the S700 test. I’ll guess you’ll get around 18-22 mins. Maybe 25 with the lefeet. Tell us how long it took to fill the 2L when you make a video of it. :)
@@Christian_Wedoy legend you should see my last video I swam with turtles with the 1L version and show a timer of a realistic use in deeper waters. If only you could test it in the ocean also.
9 minutes is longer then I can hold my breath that's very impressive 👏🏼
I worked in a Scuba shop in high school in Jersey City Nj USA. This was 1973-4.
A man in the town invented and produced an item called. “Snork-Air”.

The mouthpiece had a small lever in it.
Instead of giving air based on inhalation, you actuated the air flow by pushing up with your tongue!
When you had a breath you let off the lever with your tongue and a spring would return the lever to the No flow position.
It did not sell well and was discontinued long before I worked there but the inventor was a customer when I filled his tanks so I got to try it.

When you mentioned not holding your breath on your way up, would it be ok to release the air as your going up or no?
Yes otherwise your lungs will expand causing serious injury
Tldr; it depends on your SAC rate and depth.
How often do you need to change the oil/water separator filter on the compressor hose??
Every time on a 2l bottle.
I think those compressors are generally not recommended to fill up air tanks that are intended for breathing. Especially without the additional filters.
But im not a scuba diver and only use my compressor to fill up the air rifle.
So im always keen to hear about your opinion.
This compressor is made for filling up small air tanks for diving, and it does have additional filters.
@@Christian_Wedoy are the filters sufficient to emit class E quality air from a hot electric pump that is lubricated with oil? are the filters purchasable and replaceable? does it have a moisture trap?
@@Christian_Wedoy No. It does not have filters.
damm what a coincidence because im going to greece this summer and im going to dive btw i really like this channel love from sweden!
Nice 😀
Curious as to how these work in cold water when using as spare air source. Can you get a free flow problem the same as a regular reg.
You usually get a free flow problem after some minutes when diving in close to freezing water because the compressed air lowers the temperature when it expands.
If you use this as a spare air source it will not freeze before after you start using it, and probably not before it is empty anyways.
If you want a spare air supply, I recommend the Spare Air that is made for that.
@@Christian_Wedoy that’s what I was thinking. I had one free flow on me after 20 min in 6°C water. Luckily I was only 15 metres down. I had a friend of mine whose reg froze 30 metres down in Lake Ontario. He had a little longer swim up. I’ve just started looking to get spare air, or another small bottle.
You could also have a extra regulator on your tank.
Btw. Nice name.
I did a show in Romania in 2018 and they did not know how to pronounce my name when they were promoting the show, so instead of Wedoy they called me Woody in the Radio commercial. Since then I have been known as Woody in Romania, Serbia and my girlfriends whole family just calls me Woody.
@@Christian_Wedoy I got my name playing hockey.
Alternate title: I made a 10 minute informative video about a product just so flex that i can hol my breath for 9 minutes at the end.
Not for divers, very uncomfortable because of pressure little time at 60 Ft but it will help you out in the 3 minutes stop.
It is not made for deeper than 30ft
“I can hold my breath for 9mins when sitting still”
Let that sink in (no pun intended).
*_Those seems to be really really dangerous, please be careful when you're trying them, as they're just reserve tanks._*
If used correctly they are just as dangerous as a normal scuba tank.
@@Christian_Wedoy Well, if it's Christian Wedoy using it here of course it's safer, but yeahhh, big bulky thing in front for a normal person would be hard to see, and react quick enough.
@@Christian_Wedoy Yeah if used correctly, no one will buy these if they have been Scuba certified. Suba diving is dangerous.
@@Christian_Wedoy Yes but, these reserve tanks are just easier to get as they come along cheaply. People buy these things without getting the proper knowledge.

Do you know your SAC rate? Because that’s the biggest factor that determines how long the cylinder will last.
No, but it is way below average
7:15 thank u for saying this, some people are just so stupid.
Are you saying that you can use it 32 ft underwater that's pretty deep I thought you said 10 feet is the best to go on those
You speak very good English.
What are those leg thrusters?
What is that water scooter you have and where do I get one?
You can hold your breath for 9 minutes? Thats impressive. Can you make a guide on how you do it?
just practice. Its about building a tolerance to co2 buildup.
Why dont they make a cable going from the bottle to you mouth? Then you can have the cylinder attached to your side?
Har du en in depth review på den? Tenker å bruke den som en rebreather når jeg spydfisker.
This guy is the reason why I don't drown
I have a Question - You said to inhale air and breath out underwater but
So far I know that if you breathe out air you will start sinking.
If you lay completely still in the water and do nothing yes. But if you swim up, no.
@@Christian_Wedoy thank you so much
I have an invention along this line that nobody has even heard about or considered that I know of, but I’m not sure who to take the idea to without getting screwed.
I liked the original idea to Youssef These as a Reserve tank when you decend as you decend and decompress but for nothing else
They can be fun to use for short dives to inspect your boat, dive down to look at something or for fun. But you should get scuba training before using it.
These should never be used or relied upon to begin with and you don't 'decompress' as you descend either, when you descend you're on gasing nitrogen not off gasing. This tiny 2L tank would barely be enough for a 'safety stop' yet alone any extended decompression stop
It would be useless for decompression, it's also potentially useless as a reserve... 1. A
Do I tighten that valve on the back of the pump before pumping?
Yes
What was the swing fans on your hips?
is it not better you take it of for a second and take it again ?
very interesting test
Those of us who have actually used stored air for a living know the true answer; "it depends".
Please do a review on the A99 aquata breather. Thanks
They are hard to find.
How long would that thing last with a couple atmospheres on top of it
Can I use _any_ compressor. For example, I have two air compressors for car tires. I understand that there might be a bad smell or taste, but will the air be safe and useable?
no, car tyre compressors get to like 10 bar, or 25 psi. you need to fill that thing to 200 bar or 3000psi
How can the bottle get hot I don't really get that
I really could use the electric swim assist thing you are wearing how would I get one. Im disabled and that would help me out alot.
Its called LEFEET.
Whats the wearable DPV, please?
Nice brooo your too good
Thanks
I really want this but im terrified im going to rubture or burst my lungs also how deep can you go without bursting your lungs when holding your breath when coming back up
if you take a breath at the surfice you do not need to worry about lung expansion. Lung expansion only happens durring diving when you breath compressed air at a depth and accend from that depth. the expanding air will cause lung damage.
@@Seaweed-mw1rr yes but how deep until your lungs expand too much
@@Eflgoat If you exhale while ascending your lungs will not rupture or expand. meaning you can go as deep as you want without worrying about lung expansion
@@Seaweed-mw1rr i will explain this more clear for you because that is not what i meant so how deep can i get when i have inhaled and im coming back up to the surface without rupturing my lungs
It's a simple maths and physics : 200Bar x 2L = 400L. Average lungs capacity (men-5-5.5L, women 3.5L), Average inhale qty - 12-14/min so, if we would take the lowest capacity 5L x 13 times/min = 65L/min, 400L : 65L/min = 6m15s :)
Im not a diver but i would buy this to sit down 10 min into my 3 Meter deep Gardenpound and meditate haha
can we use it like take a breath and hold the way we do in free diving. to extend using the time ?
You should never hold your breath when using this. Your lungs may explode
@@Christian_Wedoy , it does not have a regulator?
Such an intense stare at the camera underwater lol
do you need to fill it with air or oxygen?
air. NOT PURE OXYGEN
6 minutes? hey thats a lot better than an average free diver and probably a lot cheaper than lessons
Hey so I'm looking at this as something to get for fun and get more used to being underwater before I take actual SCUBA certification classes. I don't want to spend a fortune on this so I'm wondering if there's a cheaper way to fill it with air? Would a bike pump work? I'm really new to this and don't really know anything about air compression or anything like that.
No. You should not use a bike pump.
That would contaminate the air
Take the class first. At least then you’ll be aware of all the dangers of breathing compressed air. You’ll have more than enough opportunity to “get more used to being underwater” in your course. While your at it, ask your instructor what they think of this product. I doubt it will be favourable…
Your comment is exactly what is wrong with this product, without taking classes you will not be aware of breathing pressurised gas underwater
You should not use a product like this without training. If you're not careful you can overinflate your lungs until they burst like a balloon.
buy a nemo or nomad. those have gotten great reviews.
did you know that there is a Purge button the top on the top of the tank it's the Orange part
I need to ask you some thing. So i Wonder if the plass you ar diving is calld Pirbadet. Cus i i am from Norway and it is not so common to se a Norwegians UA-cam whit over 1 mill subs.
Ja det er på pirbadet 😀
How's Greece?
Cuse we will go in Greece pls
Tell me
Greece is great, but I have not been there since May
The main things are: NEVER scuba dive without appropriate training, NEVER scuba dive solo without special training, NEVER fill your tank from unknown sources especially from the compressor not intended to be used for breathing air and NEVER EVER hold your breath when the regulator is out of your mouth.
👏👏👏👏🔝
My old reliable snorkel looks even better, having watched this......
If you went deep enough you could consume that tank in one breath. Depth make s a huge differance.
no way you could get 15 minutes out of that Tank.I started using those tanks in 1982.He got 10 min in a pool and kept taking it out of his mouth Take one down to 40 or 50 feet in the ocean in see how long they last.When they first came out is was designed to get you to the service at 100 feet in the best conditions.If you run out of air at 100 feet it wont be perfect conditions and I doubt you will make it to the surface with out doing a free ascent from about 30 feet
It's actually pretty cool and I think if you hold your breath a little bit between breaths it would last longer.
You should never hold your breath - it is dangerous!
Diving on compressed air without proper training is just not a good idea. If anyone is interested in using this it would be a good idea to get trained in scuba
Luckily I am trained as a commercial diver 😉
@@Christian_Wedoy My comment was for folks that have not had any training on open circuit. This is sold as a fun recreational toy. Any trained diver would agree that is a bad idea
@@Christian_Wedoy And yet fills his tanks with a dodgy Not for breathing compressor :(
Where video about 2l test?
It's filmed. I'm editing it now
nice
bro these facts about lungs exploding and eardrums exploading makes me nervous to go deep
The reason why this happens is because the air in a scuba tank is compressed. As you go deeper, the pressure from the water compacts the air in your tank and your lungs and makes it more dense. If you breath the compressed air to fill your lungs at a lower depth and start to go up, the air in your lungs will expand because of the lower pressure. If you hold your breath, the air has no place to go as it is expanding and then pops your lungs like a balloon. This is why you never hold your breath when breathing from compressed air. You can still hold your breath when freediving or breathing from regular surface air because it can only compact as you go deeper and expand back to the original state when you surface.
My 0,5 L tank lasted 13 minutes at 1 meter. I'm 14 and 110 pounds
Then at 10 m it would last 6 min
that air compressior is for factries and stuff, u cant use that
I wanted to ask do u use diving weights if u do I want you to send me the best one on Amazon please
And what did u have on ur short the thing that made u faster
@@Dsh9x a scooter
What mask do you use
Can’t wait for the S700 test. I’ll guess you’ll get around 18-22 mins. Maybe 25 with the lefeet. Tell us how long it took to fill the 2L when you make a video of it. :)
Will do. Video coming soon
@@Christian_Wedoy legend you should see my last video I swam with turtles with the 1L version and show a timer of a realistic use in deeper waters. If only you could test it in the ocean also.
2L S700 test is published
@@Christian_Wedoy I saw it dude but why you remove the question about the compressor are you under nda ?
Did he say he can hold his breath for 9 minutes when lying still?
At max 2 meters underwater it's not that dangerous right?
It can be of you have very full lungs.
Still can be pretty dangerous, if you want to dive just get certified
Hello after I saw your video I bought it immediately I would like to use it to do underwater fishing.
IDK if you can use a "scuba equipment" while spearfishing or whatever
@@pedrosantos0905 yes I would like to use it to do underwater fishing but missa that it takes a license for diving of the first level.
[3:25] "This bottle takes 200 bars, which means it contains around one-hundred and forty liters." I thought that bottle holds 0.7 liters...
