I got this mini scuba tank today and I could not be more impressed with it. I'm going to use it when I go snorkeling and I want to dive down just a little bit deeper. I plan on taking it to Ginnie Springs in Florida when I go snorkeling. I have always wanted to dive down to look at the outside of the cave, but couldn't hold my breath long enough to really enjoy the view down there. This little mini tank could be used as an emergency tank in a squeeze but it only gives you 5-10 minutes of air, normally back up tanks give you a little more air time. It's made of aviation aluminum, it can take 3,000 PSI/200 Bar, it is lightweight, and great for tight places. It has a silicone mouthpiece, which is food grade silicone and very comfortable when you have it in your mouth. The tank is made very, very well and is corrosion resistant. The sticker on the tank is easily removable if you don't want it on there, I took mine off with very little effort. The purge is very aggressive, so be very careful when using it. Your regulator may or may not need to be adjusted, so have the dive shop take a look at it if you aren't certain how to do it. As a safety, if you're only using this small tank I would always use a stop watch to keep yourself aware of how much air you have left because a lot of gauges on small tanks aren't always 100% accurate. DOT has only certified this tank to 2900 PSI, and not the 3,000 PSI that's stated, so keep that in mind. The tank is very fun to use, but have your dive shop double check the settings prior to your first use. This tank is better than described and I highly recommend it!

I have a few tanks and after 400 pumps with my high pressure pump, this unit is not filling. Defective.

I needed to make a quick decision when I first had an opportunity to order this tank. Unfortunately, that made me sloppy in my research. I hate to admit this, but when I saw “snorkeling”, I thought this would be a great way to supplement a casual outing. While I am a certified scuba diver, I haven’t been able to actively enjoy the hobby for a lot of years, so I thought this would be a nice little bonus to snorkeling that would allow me to stay 10-15 feet deep for a few minutes. What I didn’t take time to understand is that filling these tanks on my own requires a special adapter, to filter oil and water, and a high-pressure pump. You can’t just hook this up to your bike pump, or even your standard air compressor, to fill it. You’ll need a special adapter and a high-pressure pump. So, if you’re going to go with one of the basic kits offered, you’ll want to be sure you already own these components, are willing to invest in them, or plan to fill this tank at a scuba store. If you want to be able to inflate it on your own in a pinch, I recommend going with the C-Black, D-Black, or D-Green kits which I believe all include the pump and adapter. That said, I spent some time reading on this and watching videos, and filling this tank manually sounds like quite a lot of effort, and I’m not sure the payoff is worth the effort if you only have 10-15 minutes of shallow scuba in mind to go along with snorkeling. It has far more potential as an emergency tank. As for the equipment itself, I’m at a bit of a stalemate for fully testing it until I either invest in the equipment to fill it or decide to take it to a scuba shop. It feels like quality though. What I can test of the breathing apparatus feels smooth, and the tank feels solidly built. If I were looking for an emergency tank to take on dives, this would be a strong consideration for me.
