NEWEST UPGRADED
S400pro mini scuba tank uses an extension tube to connect to the pressure gauge, which is more convenient for us to check the pressure gauge when diving. At the same time, our original portable messenger bag has been changed to a portable waist pack bag. You can easily carry it and free your hands to do more things underwater.

UNIQUE DESIGN
S400 PRO 1-liter mini scuba tank uses an extension tube to connect to the pressure gauge, which is more convenient for us to check the pressure gauge when diving. At the same time, the connection between the medium-pressure air hose and the first-stage regulator supports 360° rotation, adapting to any posture underwater

Good good product perfect for backup for diving also really good for having to clean your pop if you fail it good quality happy with the vendor as well
Georg (verified owner) –
Fun setup to get to new depths. Wouldn’t consider it as a scuba setup as much as a way for free divers to get an occasional extra breath. Difficult to pump up and takes at least half an hour of hard core pumping. Realistically lasts 10 minutes.
Shawn (verified owner) –
Works good. No issues with any of the items. You will only get about 10 mins on this tank at 10 feet under water.

I use this to treasure hunt in the river and it works perfect as a lightweight tank that helps me stay under longer. Easily refilled with a little muscle. Perfect for quick recreation.

I bought this for my son and he absolutely loves it. Since we live in the northern states we haven’t had a chance to try it out yet but I will update this review when we do.
The tank is a little tiring to fill but that is kind of expected.
Otherwise everything is has expected.

The shipping was fast and the quality looks good

It was a quality product. Works extremely well. No problems at all. I would recommend purchasing a high pressure electric pump which I did the hand pump works but would only use in a pinch. It takes a long time and effort to fill the tank. With it electric pump only about 6 minutes. I use it for work in my in ground pool and under my boat. Gives you about 15 minutes underwater maybe a bit more.
Over all I recommend it.

Tank and all the other mechanical parts are of the highest quality and finish. Very impressed with my new tank and regulators. The remote pressure gauge (included) is a must!
Archibald Kelly (verified owner) –
I bought a s400 diving bottle before, but it was not very convenient to check the pressure gauge. Later, I found this upgraded s400 pro. The design is very reasonable and it is very convenient for me to check the pressure gauge. Highly recommended.

Really great product. Well built. Very happy with this purchase. My 8 and 10 year old kids use these with minimal effort and difficulty.

Save yourself the trouble and forget the hand pump. Just go to your local dive shop and buy a fill tank. Everything else is awesome.

I suspected I might have a problem getting the tank filled but no probs as I borrowed my buddy’s 80 CF aluminum and buddyfilled with the supplied adapter. The regulator isn’t as smooth as my old Sherwood but worked fine. I’ve only tested the system in my pool (my initial purchase was for cleanings and repairs) as I need to add some ballast in order to neutralize my buoyancy. I will be purchasing an old 80 CF tank to refill once I give my friend’s tank back. I have the pump that came with this level but not sure if I want to use that to fill the tank LOL.

I have the smaco as a bailout rig, I bought a small compressor to fill it.
One thing that I will say is the smaco tank is soo much fun when I’m just hanging out at the pool for the day. I have probably had more use out of it by far than my actual 80cu tank

Great customer service. Goods received in good condition.
Elvis Stemberger (verified owner) –
The product is as specified in the specifications. All the parts seem to be of very high quality. In general, pumping a bottle with a hand pump does not make any sense, it is time consuming and tedious. I recommend a compressor or filling directly from a larger bottle.
Stephen Jones (verified owner) –
This is a fantastic company. I want to start by saying that I have emailed customr service three times with questions, and always get to mee within 24 hours. They are always courteous, knowledgeable, and prompt. I will continue to purchase SMACO products knowing that they always have my back.
Paul de Jong (verified owner) –

I recommend Smacko!

This is really useful.
A bit hard to draw breath thru mouthpiece. a lot of resistance – have to really suck quite hard to get air out. Also, is there a fitting to use to fill Smaco bottle from dive bottle air compressor direct – rather than having to fill from another dive bottle? thanks.
