The Oxygen Tank is a mini, portable oxygen tank for scuba diving. It’s made of high-quality aluminum alloy, so it can resist high water pressure. The tank is bright yellow/green, so there’s no chance of losing sight of it. This tank is the perfect solution if you’re on the move and don’t want to lug around a heavy oxygen tank. The mouthpiece has a pressure gauge so you can see how much air is left. Explore this online section for more of these!
