S700 Plus Mini Scuba Tank 1.9L Portable Diving Tank Reusable Pony Bottle for Underwater Exploration Lung Air Tank Kit Diving Cylinder for Emergency Rescue Boat Cleaning Backup Air Source

From the moment I unpacked the S700, I knew I was getting something special. The build is rugged yet lightweight, and the 1.9 L tank delivers impressive performance for its size. According to SMACO, the air volume is rated at 1.9 L/2 L and the tank supports a working pressure up to 3000 psi/200 bar. What really stood out: The portability is astounding. At only ~3.6 kg (the S700 spec) and just 42.9 cm long, it’s so much easier to handle than a full-size scuba tank. Filling options are flexible — you can refill at a dive shop, via an adapter from a larger tank, or even a compact compressor. That makes it super convenient. The performance met my expectations. In shallow water (~3 m), I got a solid dive time (~20-25 minutes) as listed. Safety features are reassuring: DOT/CE certification, explosion-proof valve, high-pressure cylinder design. The regulator and purge valve worked smoothly, no leaks or weird behavior. Ease of assembly was good (just follow the instructions) and everything felt high-quality.

This is a cool hobby tank for the price. You prob shouldn't get the hand pump thing that they sometimes sell in my opinion as I've heard it's tough to use. The accessory quality like the tank holder is super high quality and built to last. Easy to buy fancier asseccories like regulator if it becomes a more serious hobby. I have a few of these and they are fun for shallow dives near the coast. Nice finish quality and great for a hobbyist or someone just getting their foot in the door. I use these on the NC/SC coast and have also taken them with me when spear fishing. Didn't have any issues. Pics with real view of total package.

My son and I are both certified divers who like to do hike in and dives some times. The size makes these great for that. Value is there although at a cost. The tanks and 1st stage are good but replace the hoses and second stage with your main kit(they fit). These are just super easy to grab and go. You will not pump these up with the hand pump so either get the compressor they sell or the block that lets you fill off of full size tank. Do not buy these for your uncertified kid to use in the pool. They aren’t toys. Don’t buy u less you are a certified diver.

I bought this to use on a cruise that we booked coming up next march. Took it out of the box everything was well packed and appears to be of good quality. It fits into the small backpack nice and snug so I don't think I'm going to be worried about it moving around while diving. I'm looking forward to putting it to use!

Not happy with support but the tank works fine. Some parts are not working and very hard to replace.

I am using this mostly for maintenance and emergency diving on my boat. Easy to use and maintain.

This as proven to be a great product, but needs some improvement in my opinion. Two issues really. Firstly the whip it comes with connecting to the regulator is at least 8 inches too long and is very rigid so wants to pop out of your mouth all of the time and is very uncomfortable. I replaced it with a much shorter and more flexible whip which solved that problem. Secondly, the air pressure gauge is too small and does not rotate so is very difficult to view. I replaced it with a larger gauge which pivots so this problem was solved. I am out an additional $100 for these two items but now have an excellent set up which I am very happy with.

i'll start with the good. the mouth piece is very comftorable and the vest that holds the actual tank on you isn't bad either. However, the actual dive time advertised is falls, and it only really lasts between 5-8 minutes. very dissapointed. I only got a chance to try it out a couple months after purchase and so unfortunately wasn't able to ask for a refund on the item, which i most definitely would have done. I have diving experience so it's not that I "wasn't using proper breathing technique". It's just simply false advertisement. Don't buy the tank, it's not worth the money for the amount of diving time you get out of it.

Va genial, eso sí, lo imprescindible es el compresor porque se gasta rápido, creo que esté producto sin compresor no tendría sentido ya que con la mancha sería agotador.

J'avais déjà un model 1L mais l'autonomie n'était pas suffisante pour mon usage. En passant sur un 2L, je n'ai pas doublé pour autant l'autonomie mais cela me laisse plus de temps sous l'eau. Je m'en sert tant pour le loisir en vacances que dans mon cadre pro (maintenance de bateaux) donc très utile. Seul petit point négatif: le temps de recharge via le compresseur (plus de 40 minutes) pour arriver à la capatité maxi. Le harnais est agréable en soit et la jauge déporté est un plus (comparativement au model 1L qui est fixée directement sur le détendeur de 1er étage).

Awesome !!! I advise you all to buy it !! ( Ali from Lebanon )

best purchase for me this year.
