2L Mini Diving Tank, Is It Worth It?

[@waylonk2453]

Thank you for covering many of the basic aspects of diving, i.e. "don't hold your breath as you ascend" or "you use twice as much air at -10m as you do at surface." I'm completely new to diving, so I appreciate you delivering critical safety tips along with your opinion of the SMACO 2 liter tank.

[@crybaby2696]

if u are i highly recommend just taking a open water padi course, it gives u the certification to dive to almost everywhere in the world, and it would tech u about the many dangers with these mini tanks, air time would be heavily decreased than advertised, the dangers of exploding your lungs during accent, not enough air to depressuried before going to the surface and air quality, a compressor is very expensive and it should be meant for diving, which mean no excessce water, harmful chemicals, and worstly oil going into your lungs forming a layer, compressors have oils and gears, a professional dive shop compressor solves these issues, a small one does not. I recommend investing in to a pony bottle setup when you have your certifications.

[@justsayjay]

This is EXACTLY how people die in the water. Watching a short clip on some dropship bullshit. These are dangerous. Go get a padi open water cert and real, tested tanks. There are ALOT of things you need to know other than "dont hold your breath " please, dont just go out without a cert.

[@game-tea]

just finished my PADI open water and have to say, never go dive without it! (or the SSI/other diving organization's equivalent) As long as you have safely learnt the skills that are a part of safe diving, it's quite rare for something bad to happen but you do need to learn all ways to avoid emergencies.

[@IreneWY]

If you're new to diving, you should've learned all of this in your recently completed open water course. If you haven't, then you're not new to diving, you're reckless and a drowning waiting to happen. Go get certified

[@NeverBestStudio]

take the open water class man, it's worth it.

[@joergmaass]

Probably a good gear to do underwater repairs or inspections of your boat. In this use case, you stay close to the surface, are attached to the boat with a lifeline, but have your hands free to work, and the dive time is more than sufficient. I would consider one if going on a blue water cruise.

[@RazorRevenge]

What about for lake diving? Maybe 10 feet tops. I really want to go out and pick up trash and other lost stuff in my local lake. I don’t live on the coast so there are no scuba classes near me. Or maybe I could use a garden hoes and tie it to my boat and breath through that?

[@scavanger1000]

@@RazorRevengeI wouldn’t recommend it without any scuba training, I’m pretty sure you wouldn’t be able to breath through a hose at that depth, and even if you could it would probably get full of co2, similar to how snorkels can give you a “co2 hit” if used improperly

[@hallowedmeadow4636]

You guys are very safety. Safety. Safety. Im certified as well but to me this has a specific utilitarian use which is routine boat and anchor inspections. As sailors we have to frequently check props, inspect hulls, check anchors. This is routinely no more than 3m. Holding your breath in a sea state while trying to unwap a founled prop is a hassle, and coming up nearly out of breath you risk bumping your head etc. I would use this w a SOP onboard that states no more than 3m and 10 min. At that point the risks are less than using snorkel gear since depth and duration are not even factors.

[@jonetyson]

You do realize that the air in your lungs expands when you come up, right? This means that if you don't keep your airway open that your lungs will be over-inflated upon surfacing if they were full at depth. This isn't an issue when you dive without a tank, because at depth your lungs are not fully inflated even if they were on the surface, because the air in your lungs becomes compressed as you go down.

[@madcow5833]

Where did you get your license? They should not have passed you. It is very unsafe to do scuba diving without training and you are clearly not qualified to assess the risks.

I would use this as a self-contained emergency air system for my main system. Being a wreck diver you find yourself in situations without a direct ascent. I had an o-ring blowout on my main while deep in a wreck. But my dive buddy was right there, so after I grabbed his second/emergency regulator we attempted to diagnose the issue. Failing that we made our way out and a safe ascent. With this small bottle, it will give the diver an emergency air system in case their buddy was several meters/yards away. Overall it is for peace of mind.

[@Nederlanden-biker]

Correct me if I am wrong but it's not decompression sickness thats the greatest threat here. It's a expansion injury? If you take a breath the bottom of pool this deep and swim to the surface you could explode your lungs etc. This has nothing to do with how long your down there. It can happen 5 seconds into your dive and the chance of it happening is nearly 100% if you don't do it properly.

[@IreneWY]

As long as you keep breathing, that won't happen

[@ht-ve9fe]

Like he says in the video I would get training also since, not only do you learn a lot, you run through a multitude of emergency procedures and experience in a pool and open water. If you don't have it and something goes wrong you will most likely panic, or have to think what to do which wastes precious time. Furthermore, with training you are far less likely to end up in a situation anyway. It happened to me when I was in training, my mouthpiece detached from the regulator and I took a second to discover what was wrong, being new at the time, I naturally tried swimming quickly to the top but the weight belt made it slow since I was still learning to maintain buoyancy. Fortunately I quickly put in my seondary regulator and re-surfaced. Although I am not the sort of person to panic, it is still scary and being inexperienced and ill-educated makes your insticts take over, which for something like SCUBA diving, can be fatal.

2 liters in a bottle at 200 bar pressure (2900 psi) is 400 liters of air Basically the human breathes on the surface between 12 to 20 times per minute for a capacity of 2.5 liters in calm weather and 5 liters in effort time. By spanking an average say 15 breaths per minute for 3 liters (15x 3= 45 liters per minute) and therefore 400 liters / 45 this gives 8.8 minutes of air on the surface At 10 meters divided by 2 or 4.4 minutes and at 20 meters by 3 or 2.9 minutes. Must not have tress otherwise more air. Even use as a backup for a stop of 3 minutes at 5 meters the bottle is not sufficient It will be empty well before because the breathing of the divers will be more important due to the stress of the end of the dive.

​@@MrInterpriserlet me answer that question properly, instead of "puts you in danger". When you finish a dive you still have a higher than normal level of dissolved nitrogen in the blood. When you scuba dive people generally know that you surface slowly to avoid nitrogen bubbles forming in the blood, commonly called the bends. When you go up in a plane, the rise in altitude is the same as going up in the water, nitrogen bubbles can dorm in the blood causing the bends. We don't dive 24 hours before a flight for safety. Imagine your blood is like the liquid in a bottle of coke, the gas is dissolved in the liquid. When you open the top, you lower the pressure and bubbles appear, that's what we have to avoid.

This seems good for looking around shallow water, close enough to surface in a breath sort of stuff. My main concern is people dealing with compressed gas that have no real idea. I have seen oil on fill valves with a carbon 4,500psi tank while being filled, its exciting. People mucking around with the regs or filling around contaminants, exceeding fill capacity. With paintball we always had a bulk fill bay then a top off bay, in comps we used nitrogen. Same idea. My other concern is loosing track of depth and then you black out by the time you surface, take on water and sink down into the depths again

Quick note from someone who fills tanks for work as a diver. Please be careful about at home compressors. I don't know this guy's setup but it should be aviation or medical grade filtering to make sure the air you put in the bottle is not toxic. Also the device he is using to get air from the full scuba tank to the mini bottle is called a cross whip (with an adapter for their system I think). If you are looking for a smaller regular scuba bottle you might want to just look at getting a pony bottle. Make sure you get licenced and trained in scuba, it can be dangerious if you don't know what you are doing. Good on you for talking about breathing out, using more air, etc. For everyone wondering the air compresses at about +1 atmospheres/10m or 33ft. That means you will consume about 2x at 10m, 3x at 20m, and so on. Your regular consumption rate at rest on the surface is called you SAC rate and can be used to calculate how much air you will use.

Deeper dive will reduce the amount of possible breathings accordingly. 10 meters - 2 times, 20 meters - 3 times, and so on. fast movements would lead to deeper and faster inhaling. Let say another factor 2. So 2 L bottle should give you 10-20 minutes at 10 meters dive.

That thing is a really dangerous grey area between snorkeling/freediving and proper scuba. It is in essence a mini scuba setup like a pony bottle, but it is not marketed as such. The problem is, greater depths and longer dives suddenly SEEM accessible to people lacking the proper training, which then promptly get themselves into trouble. Therefore you should only buy such a setup if you have the proper understanding of its limitations, and with a specific use case, like defouling a boat or cleaning a shallow pool, in mind, never as a recreational or sporting device. If you are interested in diving, take a proper scuba course and learn to do it safely.

[@artloftmallorca3958]

Did you also try to use fins instead of your leg scooter? I assume if you have to use your own legs your air consumption will rise significantly and this tank would last less than 10min @ 5 meter

[@Lkshfglkh]

The thing with small tankt is that you have them on a small boat or something when you dond have a compressor so the only thing I wanted to know was how long it tock to pump it up😢

[@ZeRox024]

Okay so, im a really good diver, can go down quite deep wihout s tank and stuff. But i want to use this just to extend a little my snorkeling time and i would like to buy the 0.5l one, is that okay i mean just to extend like snorkeling time if i see something interesting?

[@ZeRox024]

But i never used a scuba tank before

[@lidewijvos]

Don't use this when not scuba certified and definitely do not mix with freediving otherwise you'll die or get long overexpansion pretty quickly. Freedriving and scuba diving are two completely different things

[@leechapa7279]

I like this video. I had an Uncle that was a diver. However I've never been scuba diving and I want to learn.

[@jonetyson]

Take a class. Just ordering one of these tanks and trying it yourself without a license is extremely dangerous in a number of ways.

[@DongeGrace]

Good evening Can this be use in river, were the depth is 10m deep and how much

[@mattharvey8712]

Bravo.....dive class.....alwise exhaul when ascending....going up.......I see no Google's......did u get the high pressure hand pump.....2500psi....cheers

[@lupitaosnaya8843]

can you give us more Details on the compresor ?

[@ram64man]

Yes agreed, always use certified compressor agents , also if left charged can led to liquid oxygen build up, increasing impurity’s and rust , leading to a dangerous tank .

[@JackieChinJR]

The moisture in the air filled by a normal compressor or hand pump is going to lead to corrosion or growing of bacteria, fungi or other microorganisms from the inside of the tank. I’m just going to stick to a normal scuba system.

[@reality-cheque]

Looks like the suit inflation bottles we used in the Navy - buoyancy in the drysuit! You couldn't breathe from it, though. Anyone remember ABLJs? (Adjustable Buoyancy Life Jackets) - pre-cursers to the BCD. These had small inflation bottles like this and could be used in an emergency, by breathing through the ABLJ's mouthpiece. Actually, I think they were even smaller than this!

[@RiverRobinhood]

Really enjoyed this video as I just got one myself

[@BigO4185]

Outstanding Video, I just ordered one!

[@Flesei]

how do you rate

[@intrepidsouls]

7:16 there is a seal swimming in your pool

[@rossbrigolimusic]

How did you stay underwater without weights and bcd?

[@meneerke]

what type or brand of compressor are you using this video?

[@dalefunk2709]

or to save time bring both. refill small with large. while diving use compressor to top off large.

[@Jordi_the_onewhoknoks]

I was peacfully watching the video Until u Said the price I had a hart attack💀but no hate thanks for the information! I expected it was gonne be like 30€☠️ love Your video’s🥰

[@jerrymoney1479]

Did he says the tank can no longer be used after 2 years ? It’s such a bummer .. it’s a deal breaker to know that ! 😢I wanted to get one to keep in hand as I probably use it once a blue moon.

[@poppetrurazvan3900]

Hi. Just present this to Bahau people. I think it will be a great seller. Wonderfull kit. Thanks.

[@nicod8041]

Really nice Video! I only have 1 Question left. What mini compressor do you used in the Video at 3:17 ?? Friendly greetings from Germany

[@MrGrantgoulding]

Could I be ok to use this simply to dive under my boat to clean the prop of the regular fouling it gets?

[@kelalamusic9258]

That was a very informative video. But how deep were you diving in that pool?

[@carstenschops7797]

It was 5m deep he said. Using a "scooter" to move which likely saved air.

[@BRYKS22]

Glad to see you on youtube old friend.

[@Dannysoutherner]

I'm not sure a hand pump can make 2000 psi or more can it? Pumping up a bike tire can be taxing enough.

[@mattharvey8712]

Bravo.........I have hand pump 2200psi........the gauge on pump 4500psi......water cooled ......cheers

[@martintursic238]

So you pay 500$ and it expires after two years? I was considering this as a handy thing to have on a sailboat if my anchor gets stuck or I have to do small underwater inspection of the boat, or free the propeller if a rope or other trash gets stuck there. But 500$ every two years seems to be quite expensive. EDIT: On SMACO website it says the tank should be inspected and serviced by a qualified professional every two years, so I guess that means it can last much longer if it's serviced regularly.

[@LuciTulcea]

Are you deaf? The guy is the video said three times the lifespan of the tank is three years, not two!

[@odomn]

I'm certified. I see so many issues with this little tank. 5 meters seems safe enough, but it is pretty easy to dive to 20 meters without even realizing it. The guy using this is not going to have a depth gauge or a pressure meter and will not know how deep he is or how much air he has left. He won't have a BC. All of a sudden he is 20 meters down and run out of air. That is a time for panic. Hopefully he can make it to the surface. Much better solution for shallow dives by amateurs would be a hose with a floating pump. The tether limits you to 10 meters and you cannot get yourself in as much trouble. And as an added bonus you also have a diving flag.

[@Tjkruse9889]

Been looking at getting one of these tanks to collet fishing lures at my peir witch from the top of water to ground i like 12 feet would i have to still take a class to safe

[@clemontclemont]

If you would like to use diving equipment you should definitely do an OpenWaterDiver certification. You can get easy hurt or die if something goes wrong.

[@odomn]

I'm certified. You really can't get into too much trouble with this tank at 12 ft because it won't let you stay down long enough. But it is easier to go deeper than you think, and then trouble, serious trouble, can be found very easily. If you refuse to get training, which by the way is a lot of fun and less than this tank costs, then get a SNUBA. Much safer. Also cheaper, as you don't have to buy a compressor. Nobody will fill this tank for you, and you can't use your garage compressor.

[@prod.byjrnbeats1336]

what is the name of the compressor please answer me i need that

[@danjcla]

Read up on this topic, I took was going to get a PCP Airgun Compressor for a tank like this, but it turns out for science reasons even slight contamination of compressed air can be really dangerous, esp. If done often. Dive Shops and FDs have all kinds of filters and stuff on their fill stations, and get tested all the time. Getting a safe setup even used was on the order of like $3k. I'm currently looking into getting a large cascade tank to get filled (something bigger and higher pressure than a normal scuba tank) and then use that, plus maybe a booster pump which are far cheaper (let's you pump all of the air out of the bigger bottle). This will still not be super cheap but should be less than $1k used.

[@prod.byjrnbeats1336]

@@danjcla alright thanks mate and yesss it seems very dangerous to buy just anything

[@P.S.009]

Great review. I have one question. In general, does wearing a scuba tank increase or decrease a diver's buoyancy, assuming no BCD? Or more to the point did this Smaco setup act like weights on your buoyancy?

[@emeraldvirgo]

Using the full-sized tank, I find they don't make me more buoyant. The air is so compressed in that tank that it increases the air density exponentially. Coupled with the metal material of the tank, I would think that they wouldn't make someone more buoyant.

[@peteskyrunner4845]

When it's full with liquid gas it will be heavier than water so will decrease buoyancy but as you use the air the tank gets lighter so will become neutrally bouyant. When the tank is empty it will increase bouyancy.

[@petermichaelgreen]

@@peteskyrunner4845 The air inside a scuba tank is still a gas, just a gas under high pressure. Oxygen and Nitrogen don't become liquids at room temperature under any reasonable pressure (this differs from the likes of Propane and Butane and even CO2 which can be liquified at room temperature with feasible pressure).

[@petermichaelgreen]

Roughly speaking a litre of volume gives a kilogram of buoyancy. This tank is adverstised as having a capacity of 2L and a weight of 6.5Kg. The external volume is probablly a little bit bigger than the capacity but I would think the tank overall would stil have negative boyancy.

[@dbfuentes]

​@@petermichaelgreen also take into account the material of the cylinder. Aluminum tanks are negatively buoyant when they are full, but become more positively buoyant as air is consumed. This means that by the time an aluminum tank is empty, it will float to the surface. Steel tanks also start off negatively buoyant, but they typically remain so throughout most of the duration of the dive

[@wishbone5785]

Loved your video mate, good stuff. I'm amazed at people having a go at you for presenting some simple facts such as get scuba training before using such devices. And did you find any used plasters or condoms on the bottom of the pool?

[@Christian-vc5qv]

I had a d deep and i lost it underwayer for a few days the dive shop said it was crap and not safe because there was aluminum flakes in it.

[@Enonymouse_]

You need to use a compressor designed for breathable air, very important detail!

[@jumpship88]

They should make them 300 bar with tl5 to 7 litres of capacity. The vest should also have a mini jacket-wing bcd. Id definitely buy it if that were the case.

[@TheFrogfeeder]

I’m looking for something for wildfires, I live in a high fire area, and I’m looking for those few extra minutes if I ever need them. I have a 40mm mask for smoke filters as my last resort, but I was thinking this unit would give me an edge if I ever have to battle an encroaching fire with my firefighting trailer I made.

[@chrisphilhower6029]

I have a 6CH Spare Air. Which is Way Bigger than 2L. It's a bit Bulky. Like the idea of the Air Hose and Separate Reg. My Pool is Overcrowded. Never asked if I could Test it. I'm Not Scuba Certified. Can't afford the classes now. I could probably pass the Book Work without issue. Even I know about the Breathing on Ascent. Boyle's Law. Gas under Pressure. And the Risk of Popping a Lung. And DCS. I do a Modified Freedive. 90ft Breath Holds across the pool. Swimming along the floor. Then straight up the wall. I have to Watchout for CO2 Buildup mostly. I Wait about 1 1/2 Minutes between them. A few breaths to remove the excess CO2.

[@enchantededition6879]

I’ve ordered two ready for my first cave dive 👌🤣🤣

[@XtreeM_FaiL]

Next week. Mini parachute, is it worth it?

[@tonystites2134]

How do you know you are not getting water in your tank or oil with that little compressor?

[@WorkBob-m5h]

Was the answer about two breaths at 60 feet?

[@olagisrarikis]

No one should use this or similar setup without a diver's license PERIOD! 2L at 200bar is 400 litres. A person in good condition and relaxed uses about 20L/minute at the surface so will use 40L/min at 10meters. That gives 10 minutes or maximum 7 minutes using the rule of thirds, that is always exit with one third of what you started with. If you are under stress, cold and/or physical exertion you can easily go in panic mode and use 10 times the air and then it's gone in under a minute.... and never, ever dive alone. You should always dive with a buddy and both have a spare regulator (and a spare brain)....

[@CubanCigarAndSandwich]

Great video. Informational. 👍
