1 Liter Dive Tank Review: SMACO/DEDEPU 

That’s good to hear. I always love people who get an actual scuba. But these tanks can be dangerous if you don’t understand the safety. Welcome to the club brother!

So within the regulator itself there is a small adjustable lever for the purge valve. The issue was quality control, because the lever is slightly too high and is depressed when the top is screwed on completely. It wasn’t a difficult fix, but I definitely wouldn’t recommend taking it apart unless you know what you’re doing.

That’s way deeper than I would’ve gone. I’m also surprised it lasted 13 minutes at 65 feet. What did you use to check your depth?

i am a advanced certified diver.....i find this nearly impossible and to LIVE doing what you say you did

OP works in advertising for dedepu 😂

Aren't you concerned with air filtration quality? I had been looking at Yong Heng compressor - it would cost me around 250 EUR, but air filtration system might cost 250 extra.

@@aleksandrgriadovoi9282 Diving Seperator PCP air compressor 4500 Psi Oil Water Filter L350mmOD49mmID36mm www.amazon.com/dp/B07KQVC5SZ/ref=cm_sw_r_cp_apa_i_JBuKEbVW901BT. This is the filter i am using. I have not experience issues. This filter removes oil, moisture and the activated charcoal is to purify the air, before entering the scuba tank. When u order this accessory. When u get it, you have to invert both ends. The tube is held by one of the caps. So the activated charcoal should face the exit air hose leading to the tank. From factory is set up backwards. And y dont want the moisture to hit the charcoal first. All you do is to take the quick connet nipple and screw it on the cap that holds the tube, in. And the exit house that hooks on the tank, screwed on the cap, that faces the activated charcoal. And based on your question, again. You wont have any issues. The air comes out well filtered. Plus you would be using food grade oil, which is very important. What i do after every fill., i turn the compressor and close the bleed valves. Without being plugged to the tank. To purge water from the white cotton filter. Inside the black casing. Then i unscrew the casing, ane blow the remaining moisture trapped inside the the quick connect threaded head. U can use a clean cloth and wipe the inside. Then i do the same with the long tube filer from this link. Because if u dont wipe or blow off any remaining moisture after every fill. It will build up, and ruin your desiccant. The clear beads from the tube. Cutting off their working life. Too much moisture will swell them and turn them yellow. But if u do what i say and keep a good habit doing it. It will keep that tube dry, and working good for very long. By the way. Look at the item pic from the link. If you look at both ends. The quick connect nipple. Should be on the opposide side. Not where the charcoal is. So u unscrew the nipple and the hose with a wrench. And switch them off

@@henrychen2895 Is the same system pretty much. Same head regulator. No need for me to buy it

I agree. A friend said it’s a good thing to have handy if you own a boat and a dock and need to search for items lost in the immediate area.

@@allthingsrandom8137 Is that kind of perfect?

Any diver would be more then happy to help out any reason for us to dive

is cheaper to buy 3 tanks keep them full and ready... just a filter is the price of a new tank and if you don`t know anything about filling tanks ,remember ,these are high pressure tanks about 3ooo psi bomb that will kill anyone close if they blow for lack of maintenance ...imagine that your car tires are only average 30psi and when they blow is no joke !

whats that?

Hey luffy

Check out the 2 liter Smaco I put up a few weeks ago.

@@allthingsrandom8137 I use a lobster neckweight so the 2 liter vest doesn't work very well for me, I like the fact that I can have the tank on my chest instead

The amazon links do not work, how did you do it? Anyone knows the exact model?

@@antibyto4579 hello we have a updated model with regulator for it, you can check.

Yes, that is what I always recommend. I recommend that someone snorkels over what they would like to go down and see, then use the apparatus to dive down and kind a look around for a little bit and then go back up safely. I did just released a video a few days ago that offers a review of the 2 L dive tank from Smaco

Works great. Takes literally a few seconds. I haven’t done an update video on that because the pools have just opened up and the lakes here Alaska have just warmed enough to where they’re not frozen over. I have probably 10 Dive things to do in the next month and a half.

I’d say you’re fine as long as you don’t pass your air bubbles. Honestly, you’d probably be fine either way, but just to be safe

I’ve heard of some people using it also to check out the bottom of rivers and lakes that are very popular, for some treasure hunting.

A trick: you can watch movies at Flixzone. Me and my gf have been using them for watching a lot of movies lately.

@Kaysen Albert definitely, been using flixzone for since december myself =)

@Kaysen Albert definitely, been using flixzone for months myself :D

Go away you obviously fake alts

Go to padi.com and you can take online course or you can search for diving shops around you. If you do the online course you still need to pay instructor, so it would be wise to search the nearest diving shop and discuss the rest with the instructor. I'm also considering it, although I don't have much time cause of work.

I think it depends on how fast you want it. I own the .5 liter smaco, and ordered it from eBay. On eBay it tells you where it’s coming from, and I ordered one that was coming from the US and since I live in Alaska it got here within the week. Similar to Amazon. So if you don’t mind waiting, and it saves you money, always order from the manufacture because in the end it’s the same product anyway.

@@allthingsrandom8137 ordered one from them in China and came here to Ireland in 6 days

3:41 you can see the stage 1 regulator. On the front is the air valve and to the right is the nipple cover is a small black rubber cap. That’s where you fill it

@@allthingsrandom8137 thx so much

LOL. OK I must say that slightly hilarious. Where in Pennsylvania do you live? I am from West Virginia originally.

OK, it’s sort of depends. Let me throw it out like this. The 1 L bottle is actually 6 ft.³ of air. So technically 80 ft.³ of air to 6 ft.³ of air would be just over 13 fills. But as you start dropping the pressure of the tank, you’ll never be able to fill it up to 3000 psi again. So basically you’re looking at a couple full tanks, and then a bunch of partially fillEd tanks

@@allthingsrandom8137 good to know. I’m trying to decide on a quick and dirty solution for staying down an extra minute or so when lobstering at 10-20ft. Or I could just rig up a hookah system off a 80cf tank on the surface with a long hose. We move around a lot so full on scuba is not practical when getting in and out of the water alot.

Dave Cavanaugh that makes sense honestly I think that a line from a steel 80 is safer, but it wouldn’t be bad to have the 1 L as a back up. At about 10 to 20 feet, if you’re calm and you’re used to working in those conditions, you can probably get easily 10 minutes on the 1 liter

It’ll work just fine, if your certification is expired a scuba shop will not fill it up. There are other ways like the manual pump, they also have electric pumps. Keep your breath rate low and your heart rate calm and you should be fine

I did a re-review of both the 1 liter and .5 liter and basically went through all the safety hazards of using these things

Good question. Probably

you are not supposed to use any teflon or tapes on joints on scuba gear, this are life support systems not general plumbing ,it is all about the "O" rings that seal the system and tight enough.

@@frankc6430It has nothing to do with the O ring. It has to do to prevent the connction from losing up, due to body and head movement. One time i ended up stripping a thread, from wrenching to much. I use teflon for Hi pressure connections and i havent had any problems since. And also The o ring on the outside swollen up too much and ended up separating from the edges and eventually breaking

I guess I should’ve been specific with “I fee like it’s make of very cheap plastic”. Because I agree, but the plastics used on others are more heavy duty and durable

I haven’t had an issue getting up to 3000 psi. I’m not in the best of shape, but it does get harder and harder as the time goes on. As long as you have the high-pressure manual pump, there shouldn’t be an issue. However, they do make high pressure electric pumps. I did a video reviewing minidive and their electric pump

So the issue is not a “super” big deal. It’s just note worthy. So it’ll be ok, as long as the regulator is not taken on and off constantly. Some would disagree, but it’s fine if you just leave it on

Yes, they can be filled with a specialized high-pressure air compressor like the one that Smaco offers

Depends on the pump. I reviewed the tanks and showed different ways to fill them up. As long as the connection is the same, it’s filtered, and it’s high pressure, then Yes

Yes, i’ve done several other videos with dive tanks and I’ve shown that you can fill them from other tanks. You just have to have the proper adapter called a whip.

I would go with the SMACO. A little more pricy, but I did a review on the .5 liter about two weeks before this one. Better quality all around

From the reviews I’ve done and the other videos I’ve seen they are all basically the same. However, I feel that SMACO has better quality control than dedepu and I’ve never dealt with Dideep. But looking into it seems much like the other two. I’d say it’s a coin toss

@@allthingsrandom8137 Thanks for quick answer! I think I would pick up Smaco then and pump from other brand (because of price and taxes). Smaco Official answered me just too: "DIDEEP is a fake, they were our supply chain before. Later we removed it from our supply chain list, and they began to copy our products. Their products have not passed any safety certifications, and there is a great risk."

just get certified first and then buy proper $1500. equipment .......saving $30 is not worth your life on these units

Everything comes in the kit minus the pump. The pump I got from .5 L tank. So the only thing you would need is a way to fill it up, and it does have a tank transfer valve so you can fill it up from another tank.

@@allthingsrandom8137 cool. Thanks👍

Awesome

PeterC Gamelin it just depends on the air pump, has to be high-pressure, whereas most aren’t , and you want to have some sort of filtration system.

It has to be something like this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N5-hes9-a3U.htmlsi=EiFJwZzllayBeZGj

Check out minidive, I have some products coming in from them, hopefully I can get the review out beginning of August. Definitely better quality stuff

About 45 minutes

Not a standard air compressor, you need to specialize high pressure air compressor

How many times can you fill the lil bottle from the dive tank?

@@ryanlee6147 honestly I never really counted. With each fill you will get a pressure drop so you can fill it 20 times but you have to take into account that you aren't getting the full 3000 psi after around the 10th fill. I let the kids play with it in the pool but when its truly mounted for a dive I fill it once from a fresh tank to ensure I have as much air as possible when i need it.

It really depends on how much you breath. So my breathing rate may be different than yours. For me, the most I was able to get was about 8 minutes. That being said, I was calm, and my breaths were steady. If your heart rate is up, or your swimming hard, or breathing hard, 5-6 minutes, maybe

And a smaller person, like my wife, may get 10-12 minutes out of it

Anyone can use it, yes. You can buy them on Amazon or eBay. It does not cause any breathing problems as long as it’s properly used. There are several health risks while breathing under water, that includes at any depth. For example. Even at something like, 12 feet(3 meters), which is not deep by any means, can cause issues if you run out of air, hold your breath and surface. The correct way, even if you run out, would be to breathe out slowly the entire way to the surface. One main rule: never hold your breath under water if you have taken any breath under pressure. Either hold your breath the entire time or breathe the entire time.

Sumathi Viyas well that’s going to be a full size 80 or 100. My standard dive when actually scuba is around 45 minutes depending on the depths and safety stops

I won’t recommend it. The air pump “filters” but how much is debatable. A standard pneumatic normally has oil particles in the air.. so the answer is both yes and no... Doesn’t help, I know

@@allthingsrandom8137 Does that apply to portable air tanks cause I know you can purchase the optional air compressor with the scuba kit. It just takes so dang long when using the glorified bike pump.

MillennialsSuck I am familiar that some do come with an electric pump. But those are normally very expensive, because they’re built specifically for scuba tanks. And the price of them is worth me pumping it up by hand.

I have a diving video too with 2 tanks on me. Smaco S400 and DPL tank

Becareful with other pumps, with no filtration system. Dont just focus on filling it quicker. U dont want dusty contaminated air in it. Plus the build of moisture inside

Got really no reply. 20 minutes is a bit unrealistic even for 10 feet, the only thing I would recommend is getting used 1 L tanks, and getting at least two. I know you can buy .5 L used spare airs for next to nothing

Check out here. Over 80, but many different sizes. www.leisurepro.com/p-aqutp13/catalina-pony-bottle-tanks-yellow-with-pro-valve-13-cu-yellow?gclid=Cj0KCQiA962BBhCzARIsAIpWEL1c2QjvzREZYSTG7TnDm5MWqLKekQ1jwxy2gM9qrYjktYf_OeLy_GoaAvGlEALw_wcB&gclsrc=aw.ds

super zachary 63 it does. Works quite well and consistent

If you can wait about 4 days, I’m releasing a re-review on both the 1 liter and .5 liter. I’ll be going filling both from the pump as well as a scuba tank

All Things Random see if you can find away to put air in tank via Tyre compressor air pump. As scuba air compressors are $$$ Looking forward to next review.

Nathanial Lischak I don’t own a green screen. They are sound panels in my small garage studio

The issue with that is most air compressors don’t have the capability to fill a 3000 psi tank, Most compressor is running just a couple hundred psi so the answer is no

Now I am testing out a high pressure air compressor for these tanks in the next couple weeks, it’s from A company called minidive

SMACO air compressor is coming! link: www.amazon.com/dp/B09HC9T8B7

Champ Bauce if you stay above 25-30 feet, it’ll last between 7-11 minutes

About 400 pumps for the .5 liter and about 1100 for the 1 liter

Computers just do their jobs and don't ask questions. But still, I bet you could damage your full lungs if you held your breath ascending from 12' with 1.4 atm of pressure in them . . . The computer could be there to remind the uncertified to keep breathing!

@@totheknee ya i bet you could damage if you hold your breath! Not when your breathing

Your shop air compressor will only pump out a few hundred psi max. You need a specialized high pressure air compressor. That does at least 3000

DEDEPU

Check out the re-review I dive in deep to all the dangers. No pun intended

I’m putting together a re-review this weekend for both the 1 L and the .5. People really think that you can’t get hurt even in shallow water, but breathing any compressed air under water at any depth can’t cause injury

@@allthingsrandom8137 very good point. What can you say about the airbuddy - they have a 20 foot hose, can you get injured breathing that and being down at that ~20 foot depth?

Jose Rhode Island as long as you’re breathing throughout, and you’re breathing a steady pace as you come up, then you should be fine. Compressed air is compressed air doesn’t matter if it’s coming from the surface or coming from the tank.

@@allthingsrandom8137 thanks for your quick reply!

Maybe, but c'mon, he was at the surface already. The problem with holding your breath only applies if you have pressurized air, usually from well below the surface. I could dive to 200 ft and back if I took a breath at the surface and held it the _entire_ time. Free divers do it all the time. Alexey Molchanov could do 400 ft holding his breath, no problem.

They could, it at that depth we are talking a couple breathes. It recommended unless it’s used only as an emergency at that depth

I'm a certified Commercial Diver and Scuba Diver, please for the love of god don't even try it. That's a great way to drown.

About 8 min

That's it? Really? It says on the description 20 mins 😐

pilipinas aking mahal112 your be lucky for 12 if you are good at controlling your breathing

Depends on your cardio strength. For more it was a 100 pumps then a break, then 100 more. About 30 minutes of cardio

@@allthingsrandom8137 shiiiiish that's a long time pumping I'd just rather hold my breath lol thank you

At 40 meters it is more like 1 minute lol

@@wowfreaker Only an idiot would try to snorkel to 40M with it lol. Yeah you're right, the deeper you go, the quicker the air will run out. But I think most people will use it between the surface and 5M so they should get a decent time with it. I'm thinking of getting one as I love snorkeling. I am PADI advanced open water certified so will know how to use it safely.

Kurt Steiner on my rig, I use a 19 cubic foot tank as a reserve tank, because at any real depth, a liter Is nothing. That’s why “if” a person gets it I recommend staying at 1 bar

So what I was saying was I would stay above that, because if you go below say 30 feet, the nitrogen from the air that you put in because the standard air mixture is about 80% nitrogen 20% oxygen, and there’s a recommendation that if you go below that then you need to do a safety stop at 15 feet. That shouldn’t really be necessary if you stay within a certain limit. As for the air in your lungs, I also completely agree. It’s extremely important especially when breathing underwater under pressure to make sure that you breathe out and don’t hold your breath coming up

And if you are into scuba, I got plenty of videos in the future testing out both expensive versus cheap equipment.

No nitrogen in the tank? What do you think is in there? It's not purely oxygen. It's filled with regular compressed air, just like the common scuba tank, which contains 79% nitrogen. As you descend the partial pressure of that nitrogen increases relative to your tissues, leading to more nitrogen being absorbed into your tissues. When you ascend that nitrogen needs to leave the tissues. A bit of excess nitrogen is no problem (I won't go into the numbers now) but too much leads to DCS unless you ascend very slowly. That's why people should use a dive computer whenever they breathe compressed gas under water. The risk with these tanks is that people without training and without a computer will exceed the safe limits.

If you think there is no nitrogen in the tank, you need to go back to your instructor who taught you to dive and give back your certification card. What do you think is in air?

There’s a few videos after this, one where i review Mini Dive Tanks. They sent me an electric pump and it is waaaaaay easier

@@allthingsrandom8137 yes I watched a few..a mini pump that works off off car battery would be great...just not sure how long they last and costs..the 1/2 liter seems doable using hand pump..thanks

you have to use a specialty high pressure compressor. Has to be something that pumps over 3000 psi, which is not a standard compressor

Oh ok, is it expensive ?

@@ThePiter Smaco has one on their website. A few hundred dollars. But, it is portable and it can hook directly to a car battery in the field

Your air compressor does not have enough psi to actually fill the tank. It takes a special high pressure compressor to actually do it

@@allthingsrandom8137 I got you. But how does s hand pump do it then?

@@Rbhawk3rd it’s not a standard hand pump. It’s a high pressure, and I’ll tell you it is not easy to hand pump. Without a special high-pressure hand pump, a standard hand pump wouldn’t get it past 30 psi. Let alone 3000

@@Rbhawk3rd ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-N5-hes9-a3U.html Here is a rig from Mini dive, that also had a high compressor electric pump

@@allthingsrandom8137 Thank you do much for the response. 😊

Like for oxygen? My recommendation for first aid would be a breathing bag and mouth piece for airway management

No, if it isn't explicitly serviced as oxygen-clean then don't use it for anything other than air. You'll have a significant risk of a fire.

I did a “re-review” where I say basically that. Except I give the depth as being far more shallow as the deeper you go, to include an upward of 25 feet is deep enough to compress everything and cut the air to basically half. my concern honestly for people is an over expansion of the lungs if they run out of air suddenly then hold their breaths coming up. I think it’s a decent kit, but the other video explains all the ways it’ll kill you

total BS.... wrong resurface from 1,2m already can give you big issues...

It doesn't even have to be that deep. I have personally seen someone die from a rapid ascent from 30 ft where they held their breath and bolted to the surface in a panic. Embolism of the brain, dead instantly. People are gonna do what they are gonna do, but non-divers don't really understand how dangerous breathing air underwater can be.

🤣🤣

Perhaps a head to head in the future of both!
