Scuba Tank with mask 0.5L, DOT/CE-EN250 Certification | aluminum tank meets safety standards, ideal for recreational snorkeling and diving use

This is a lot of fun. I've used it to go lobster diving, snorkeling around until I see those tell tale antennas and then diving down to capture them. If the bug lodges itself in a hole and it seems like it's going to take longer than i can hold out without resurfacing, I can simply use the tank for an auxiliary breath. That's a lot easier than dragging out all my scuba gear or weighing down my kayak when I'm just going out for a bit. I particularly like that the tank is refillable at the dive shop. When these types of mini tanks first came out they were one and done which I found to be incredibly wasteful. The only reason I didn't give this device 5 stars is that it does feel a little unbalanced and cumbersome but I guess that's the price paid for such convenience and flexibility.

Does not come with an air pump. Had to order separate. No…your bike tire pump will not work. Need a high pressure pump.

This fit great and sealed off perfectly. I love the versatility of using the tank or just snorkeling. My only issue is that I couldn't seem to get as good of a breath using the snorkel as I can with my other pure snorkel mask.

It's compact and easy to carry with enough air for emergencies to make your way to the surface. Recommend!
