Pretty neat back up air tank, comes with a pump and filter to refill.

The mini scuba tank is made for short underwater dives and emergencies. The constant pressure breathing valve works flawlessly and feels very safe compared to older designs. The 6061 aviation aluminum build is solid yet lightweight and I love that the tank can be separated from the valve for easy air travel. It truly delivers close to 20 minutes of underwater breathing (depending on depth and breathing rate) which is perfect for boat maintenance underwater photography, or pool training. The multiple filling options are very convenient and the included scuba adapter makes refilling quick and easy. Overall this is a reliable portable and well-designed scuba tank an excellent choice for recreational divers and explorers.

Hard to pump the air. Not for me..

This is a great kit for someone with basic scuba diving knowledge. If course when you go down with this make sure you are allowing the air to escape your lungs by blowing out slowly the entire accent. This unit is highly portable and it even comes with the adapter you need to fill up the tank via a main tank. This kits great for an extra emergency air or snorkeling when you just want a little time at the bottom.

My grandson is anxious to try it out. We were disappointed in the hand pump
