You can use the small SMACO S500 to do short dives without heavy equipment.
I do however recommend you get a scuba course.

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.

[@king-yz7ib]

9 minutes is longer then I can hold my breath that's very impressive 👏🏼

[@airportbum5402]

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.

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.

"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.

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

You should check out this thing. It is down to 9ft. kzbin.info/www/bejne/nn7Yo5Kqmrp0aM0

[@shootingbricks8554]

So at 10 meters under water the pressure basically doubles from the surface. In essence that same volume of air will be less at 10 meters.

[@Christian_Wedoy]

The same volume of air will be half at 10m

[@bartvanriel6767]

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

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 KZbin 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.

[@Christian_Wedoy]

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.

[@user-fn8pf2pu6w]

I didn't understand how your lungs would burst can you explain to me?

[@MrImadeU]

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

[@earlgrey2130]

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.

[@felipebouzonnoexperienceon1160]

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.

[@Christian_Wedoy]

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.

[@Sherwoody]

@@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.

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 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.

bro these facts about lungs exploding and eardrums exploading makes me nervous to go deep

[@kick0777]

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.

I breathe out autimatically when going up while freediving am I the only one (It would seem just natural with a tank to breathe out while going up for me)

[@calleigh9898]

Yeah when I’m just casually swimming I do that so I don’t have to just stay at the surface, breathe out, then breathe in. When I breathe up before I go through the surface, I can just take a deep breath and swim back under.

How's Greece? Cuse we will go in Greece pls Tell me

[@Christian_Wedoy]

Greece is great, but I have not been there since May

[@OzzySafa]

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]

Will do. Video coming soon

[@OzzySafa]

@@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.

[@Christian_Wedoy]

2L S700 test is published

[@OzzySafa]

@@Christian_Wedoy I saw it dude but why you remove the question about the compressor are you under nda ?

[@SimonAmazingClarke]

A great bail out bottle, but not much use for anything else.

[@Tritchet_]

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]

This compressor is made for filling up small air tanks for diving, and it does have additional filters.

[@AviRotstein]

@@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?

[@gertebert]

@@Christian_Wedoy No. It does not have filters.

[@oldschoolsurfer]

If you went deep enough you could consume that tank in one breath. Depth make s a huge differance.

[@richardgregory4111]

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

[@flitsplik5750]

that air compressior is for factries and stuff, u cant use that

[@Cesarius894]

I liked the original idea to Youssef These as a Reserve tank when you decend as you decend and decompress but for nothing else

[@Christian_Wedoy]

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.

[@spooks1089]

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

[@leerigby5735]

It would be useless for decompression, it's also potentially useless as a reserve... 1. A

[@ennaber]

Where video about 2l test?

[@Christian_Wedoy]

It's filmed. I'm editing it now

[@kevinaa1622]

Not good for diving but great for scuba diving depths

[@timi3114]

At max 2 meters underwater it's not that dangerous right?

[@Christian_Wedoy]

It can be of you have very full lungs.

[@traydog1257]

Still can be pretty dangerous, if you want to dive just get certified
