Review: 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.

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.

## Features

- HOUVAN H400 The HOUVAN H400 breathing valve for diving tank adopts the latest constant pressure design, which can also be adjusted by opening and closing the control valve, which is safer than the previous direct suction breathing valve. The diving tank is made of 6061 aviation aluminum, which is extremely durable. At the same time, when the body of the diving cylinder is separated from the valve head, it can be safely carried on the plane and follow you where you want to go.
