1 L and .5 L SMACO/Dedepu Dive Tanks: How To, Will It Kill You, And Safety TIPS! 

Really appreciate that. I know people will use it no matter that I say, but people really don’t understand just how dangerous it can be. I did a review on the 2 liter which is even more dangerous

Thanks! I am heading to Hawaii in a month and I’m taking these things with me to dive the reefs work. Stay tuned

Yes, thanks for this, I almost regretted buying the Smaco 400 pro (which I think wasn't yet available when you made this), as I suspected having the pressure gauge separate doesn't justify the nearly double in price over Dedepu - but was happy to see my intuition about the .5 liter confirmed by you. Suscribed.

Dude, thanks for the comment. I am taking this to Hawaii in two weeks and seeing just how well it does on the reef. Honestly, super dangerous. I was teaching my 12 year old the safely and it hit me just how much the average person is unaware of the dangers. Thanks again!

I'd get certified instead. It's worth the few days it takes and you'll enjoy diving for an hour.

LOL

Appreciate it!

😐😐😐😐

better get a swim vest if you are worried about that. That thing helps breathing under the water but it doesn’t help with long swims it just slows you down.

Just get a snorkel.... You can swim indefinitely that way. Get a decent snorkel that has a dry top ball valve. A full face snorkel mask would make it very easy to carry and deploy in an emergency. You can get a suitable mask for less than $50 all day.

Yeah, not so good. Check out the channel about a month or two ago. I did a video with Minidive brand tanks. Way better and the pump is electric

Honestly I don’t think the tank is a bad thing. And I think the quality is there. There are some nitpicks but overall I’m taking it with me on my next vacation. My point is when it comes to stuff like this because you use knives as an example, people understand inherently knives can kill people. People don’t understand that breathing compressed air underwater if surfacing incorrectly can do just as much damage of not worse. So I think that fallacy is false. Thanks for the positive comments about the advice. I think people will do what ever they want anyway, I’m just trying to reduce the risk

SMACO scuba tank has DOT/CE certification.

ok... it's really fun to figure ideal gas however in the diving world it's a waste of thought to go to indepth. For mole and effect of Avogadro’s law, it is possible to predict volume changes and therefore breathable gas by temperature, right? well not really. The mathematics are not the short coming. The varation in the real world can never be calculated to and specific degree. A very basic example is a diver with a SAC rate of .75 that sees his friat tiger shark. As for temperature, how warm was the tank, how warm is the surface, what is the rate of cooling, where are the thermoclines etc

Check out the video I did where I reviewed the .8 L mini dive tank, there is a high-pressure air compressor that was also tested

ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N5-hes9-a3U.html

It’s going to be comparable to the size of the tank. An example would be if you have a Tank with 3 ft.³ of air, a 80 ft.³ tank of air can be divided for a rough estimate. But you have to understand that the moment you start emptying the tank, the pressure will drop. So you may not be able to get the maximum 3000 psi after a few tanks. So you could do 3000 psi, and then the next one may be 2950, the next one may be 2900, so you’ll never be able to fully fill it every single time because the pressure in the 80 square-foot tank will drop each time. That being said you should be able to fill it up at least 8-10 times

If you are considering using any kind of scuba you should at least put the effort in to learning some of the physics and physiology that diving brings with it. If you intend to decant air from one cylinder to another then you should learn Boyle's Law which covers pressure and volume. P1 x V1 = P2 x V2 So your (80cft)12liter tank at 200bar gives you 2400lts of free air. If a 1lt bottle is decanted from that tank then both will equalise out at 185bar or 2719psi - THE FIRST TIME. Each subsequent decant will give/leave with you less in both tanks. I have been a professional diver for 50 years - navy, offshore oil saturation diver, commercial diver trainer and even a PADI instructor so I have a pretty good handle on this shit 😂. Anyway, this is a pretty sound video with lots of sense 👍

Thanks! Just released a 2 liter dive tank review this week.

Yeah, actually I think it would be perfect in a situation like that. Especially because your goal is just to breathe while you’re getting out. I just released another video on a slightly larger bottle two days ago, if you’re interested in a little more time for rescue.

This is straight from my buddy who is a dive master/instructor “well... I guess that depends. I'm looking for some good tires. What do you recommend? You'd obviously have some more questions. I'll assume at this point he is recreational diving shallow side of 100 since he mentioned Nitrox. I would hope he selects a bottle with a regulator as 2500-3500psi is a bear to breath straight (paul walker made it look sexy). I'm guessing he meant a second stage regulator fixed to the bottle like the cheapo Chinese hero kits. I'm not sure I've ever seen anyone strap reg hoses to their arms and I've dove with some dumbshits. A pony bottle is not affixed to a bc if you hope to have any usefulness but rather strapped to the back bottle. And yes you need a hose so you don't have to remove your kit, disconnect the bottle, then start breath paul style during an emergency. Does he think the hose is going to entangle him like a rogue octopus and drag him to the depths? He has probably seen a Google picture of a bottle strapped to the side of a tech diver. This is called a stage bottle. The gear intensity grows as you start adding bottles which is why people start small. It is too intense without experience. What would I do? Well that depends on the mission. I run 2 full redundant systems under ice. 3 bottles is a good solution. 3 levels of safety on any dive though not always 3 mounted bottles. I run a single bottle with a mounted pony on shallow solo warm dives and use the surface as a planned redundant. I run twinset back or sidemount on deeper/colder dives. I could talk about this for hours. My recommendation for him... Get a competent buddy, get some additional training, crawl walk run. If he wants some specific recommendation, I need some details on the mission.”

Thanks!

I wouldn't go deeper than 5 meters with these. Going deeper significantly increases the air consumption (at 10m you have half the time you had on the surface). If you're interested, just get Open Water certified. You'll have much more fun for much longer, and you'll understand the actual risks of a device like this.

@@Yggdrasil42 i know ive dived with Scuba gear on Vacation

And im aware of the risks

I absolutely think it would

they call these things "Pony Tanks" when used as backups in such a manner.

Yes, it's a good idea. I'm an offshore oil diver and when traveling offshore on helicopters sometimes these wee Pony bottles are issued to each passenger for the duration of the flight. However, EVERYONE gets trained in their use - even us divers.

Sounds like a faulty tank. There’s no reason air should leak from the knob. It can happen with liver points on the hose and regulator which is why they provide extra O rings. I’d say sent it back for another

@@allthingsrandom8137 Thanks, I just tried testing it in the pool. Despite it spewing out air, it still lasted 4 minutes.

And I learned that thing sucks compared to the bigger ones

So next weekend or the weekend after, I have the 2 L dive tank from Smaco. Which should offer a lot more airtime, but can also be a little more dangerous…

So I think this is extremely dangerous, and I did a video re-reviewing both the 1 L and. 5 L. And even worse so I have a 2 L smaco dive tank that I am reviewing this weekend. Which I find far more dangerous. Because the larger the tanks, the more false confidence people get, and the more likely they are to get hurt. Stay tuned

@@allthingsrandom8137 it's when thay sell a 12L steely with a foot pump 🤣🤣 the other worrying thing is that thay only have particulate filters in the pump so if you are pumping it up in a carpark you could fill it with toxic air

@@allthingsrandom8137 I totally agree. I've read so many comments that these things are death traps but actually their true redeeming feature is their small size. I don't think there's enough air to dive deep/long enough to dissolve enough nitrogen in your body to be dangerous. A 3L tank would allow someone to dive deeper and longer and possibly get the bends if they don't ascend safely. I'm planning on buying the 1l for using in Greece soon. Do you think dive shops would fill it for me (for a fee) as I am a qualified advanced open water diver?

@@peteskyrunner4845 dive shops have no issue filling the tanks. It’s only like a couple bucks

@@allthingsrandom8137 That's great. I will order one then. Thanks for the quick reply 🙂 Great video by the way, very informative.

Not that I already covered. Or none that I think of

@@allthingsrandom8137 I think I will be ok because my dad scuba dived

@@allthingsrandom8137 and thank you for helping me

Just don't go deep (about 20 feet) and never hold your breath.

Hell yeah it will be

@@allthingsrandom8137 amazing.. Thanks.. Great video by the way.. Very informative.

Yup

Is there a safety brief or training involved? I can just see it as a law suit if there is nothing hard lined set in place. I did a review on Mini Dive tanks. Those are higher quality

or as spare air?

Honestly as a backup would question the depths of the dive. Normally, for myself and my buddy who is a tech diver, the spare is 19 liters as a back up because the depths could reach lower than 80 feet, and 1 liter is not enough at that depth to get out safety. However, 1 liter is better than none, and most dive on No back up at all.

@@allthingsrandom8137 Yeah, I agree. A 13 or 19 as a real backup. The 1L would just be an emergency device, if my buddy is too far away or distracted. It would allow to approach the buddy and make a safe ascent together with his spare octopus. - Or it would help to ascent if I'm at around 50-60 ft I guess.

You will be fine

I mean, why not just snorkel then?

It depends on the connection. Also it depends on the filtration system. Breathing in dirty air can be just as dangerous as smoking

@@allthingsrandom8137 More so, since you are breathing it compressed. It cause enough issues underwater to disorient you or cause damage you may not catch right away.

About 45 minutes of on and off pumping

@@allthingsrandom8137 I’ve heard it can take up to a day. Is it really only 45 minutes? Can you get the tank up to full pressure?

Craig.311 it depends on how out of shape you are, it only took me about 45 minutes with some breaks in between. I was really mean it definitely didn’t take me an entire day

I guess what I would say is don’t ever stop breathing whether you’re surfacing or diving. Don’t ever hold your breath, always breathe

You can use whatever, I would prefer a weight belt because the center mass is around your waist which allows buoyancy to be easily compensated for

The issue with that is the filtration system on those type of homes are poor, so you’re breathing in dirty air. Also not many things off her high pressure up to 3000 psi unless it’s specially modify

@@allthingsrandom8137 ah ok.. thanks for the info. I just found out that here in Ireland we can buy the oxygen tanks for refilling scuba tanks. Not very handy on the go is the only thing.

😐😐

no idea. the more you research the less you'll tend to find

Check out the page simply scuba. A lot of info there

Nice! I had a company called minidive send me one of their dive tanks and electric high pressure compressors, stay tuned

@@allthingsrandom8137 awesome I’m ready

?

The trouble with a full size tank is that it will enable you to dive for much longer increasing the chance of decompression sickness, especially if you are untrained. The beauty of the small tank is that you can only dive for a few minutes so nitrogen build up is much less of an issue.

Yes, as long as you remember to NEVER hold your breath

@@allthingsrandom8137 thanks

@@allthingsrandom8137 I have one more question could I teach my 13 year how to use it

​@@maddenyoung8750 if your 13 yr old is very comfortable in water. If your 13 yr old is prone to panic, don't

@@allthingsrandom8137wait so when I’m ascending to the surface I need to exhale? And when I am above the water does it matter if I hold my breath with the scuba tank even if it was accidental

Imagine trying to put this in your mouth when you can't even hold your neck straight with the force of the water. Just not practical.

It’s not for snorkeling. Even though it’s small, it requires all the safety precautions for any scuba diving. They were originally sold as emergency safety gear for capsized vessels, firefighters, and backup air for divers. These are not toys. Please use them responsibly, life is on the line.

@@It-b-Blair As an owner of a smaco tank, certified scuba diver and research nerd, I can tell you this: your referring to Spare air Rebreathers Man overboard capsule Each one of these are different. What we are talking about is bought from eBay. There’s no training provided. Sold with a hand pump. Called an oxygen bottle 😂 Dideep, smaco and many unbranded versions for sale. Buy and go. Don’t take it deeper than 3-5 meters as tank is too small

Don't forgot to add heatsinks to the pump to help cool it. Then you may be on to something!

May as well get a mini 12v dive-safe compressor for your car and be done in 10 minutes… enough time to drink water, take care of your finds, and use the lou!

You’re not wrong

which hookah gear would you recommend? There's a lot of new companies out there now that lithium is ubiquitous.

Yeah, I don’t disagree with you. A lot of times that’s what a lot of my buddies run is a 19 ft.³ tank as a back up. They are specifically tech divers, but most basic PADI divers don’t even use backups

Better than having nothing though. It will at least give you enough breath to get to your buddy to use his spare regulator.

Appropriate the comment and support

Weird, I thought it was a safety lesson

That’s why it’s not marketed for scuba divers. Obviously you can’t give advise in a 20 minute video. The point is, people will use it anyway. Better give the dangers and some advise, then none at all. Even worse. Smaco sent me a 2 liter dove tank that will be out in 2 weeks. Far more dangerous than the small ones, as the size of the tank will give too much confidence for injury

@@allthingsrandom8137 I think you could just highlight the dangers instead, that might detract people from getting hurt or worse. I know you have good intentions but hearing you talking, folks might still get the wrong message. That thing is labeled as a toy but it isn’t. Imagine a non-certified average 45 year old whose mask floods at 30 feet… doesn’t know how to clear it, has a weight belt now keeping him down, starts panicking, etc… difficult situation. Dive safe.

​@@eldiabolico3750 unless the person listening isn't good in English, what he says it's pretty clear especially the risks. I'm also a certified scuba diver.
