SMACO S400 1L Mini Scuba Tank Up to 20 Min Dive Time, Portable Diving Cylinder for Scuba Diving, Snorkeling &Emergency Rescue

20 minutes of dive time is pretty optimistic, but it is achievable if you stay shallow and aren't exerting yourself. I've done 5 dives with this so far and it's worked flawlessly. Filling it with an electric pump takes about 25 minutes, but you get 10-15 minutes underwater uninterrupted, which really is quite cool. The provided tank carrier is really nice and works well. Don't forget to get a weight belt.

He have not even used this profuct to give an honest Review. And he is bashing on it, because he is the Owner of a tank and smaco is competition for him. Makes no sense to say.

Dive Portable Lungs Owner Cameron Barbeau. He ships his tanks and Pump with no protection in a prepaid USPS Box. And the tank's hardware, such as the 2nd stage, or tank connections may leak air, within its use. The gauges get full of water, and its condensarion turns the gauge Blurry.

For sure will go behond $1,000 dollars. And the Smaco S400 will still lead in design and performance. His larger tank will use the same cheap Aluminum connections.

I was pleasantly surprised at the quality of this - very good fit and finish and I don’t think if you bought this in a dive shop it would look any better. The shoulder holder works well. Those are the pluses. There are some minor minuses which I will list here:The gauge is a little hard to read the numbers, but once you figure out what numbers go with the color code, you’re fine.The mouth low pressure valve is a little sticky - in other words, as you breath in, it really takes a good bit of negative lung pressure to get it to activate fully. It wasn’t too bad - I like it a little bit that way so you don’t use so much air. Also, the front unscrews easily and comes apart nicely. There is a tiny nut on the actual valve and it looks like this may be an adjustment for this. Haven’t gotten around to looking for my tiny wrenches yet.The directions are OK, but not very detailed - for instance there is nothing about adjusting the second stage valve and the English is OK, but not great.The little cap that covers the fill nipple is not a tight enough fit. This lets water get into the fill nipple which if you’re not careful, will end up in the tank when you next fill it.Worst off, the low pressure hose smelled terribly of industrial manufacturing. Not breathing grade. I soaked and rinsed off the secondary valve and hose, and noticed a slight oily residue on top of the water. Then I assembled it and pumped up the tank to about 2000 psi to try it out. After 5 minutes using it in the pool, my lungs started to burn. I stopped, and let the air out. I rinsed out the hose several more times, noticing there was still a slight oily residue on the water. I also washed out the interior of the tank this time. I’m afraid they used an industrial hose instead of one specifically for breathing. However, it is also possible my pump contributed to this. I do have an oil-free pump, but I will now get the tank filled with scuba air and see if I notice a difference. If I do, I will update here appropriately. If my lungs continue to burn and I can determine it’s because of the hose, this will end up a one-star.

If you have no way to fill this tank properly via compression, then I’m afraid using the provided pump is NOT a solution.It’s extremely hard to use, it take a very long time to get even a small amount of air into the tank, you may be able to get about 5min worth of air via the pumping method before exhaustion, no joke.But if you are going to use a proper filling station then the product works fine, don’t push suggested limits of the product. Have fun!

I’ve used this on a few different dives now, primarily in lakes. The best part about this is the compact size. It’s easy to carry on my paddle board, and with the pump it can be refilled on the go. I’ve been using it for dives approximately 15 minutes long and have had no problems. Super fun for diving in hard to reach locations where lugging a regular tank would be impossible. This fills a much needed niche, not to mention its viability as a back up tank on longer dives. Fun to bring out on beach days and disappear for a bit.Super solid construction. Both stages of the regulator are bullet proof. Shoulder sling is comfortable and easy to adjust. Useable with or without a wetsuit. Really solid components, as good of quality as I’ve seen anywhere else.
