What Is a Scuba Tank?
A scuba tank is a gas cylinder that provides storage for the high-pressure gas used during a dive. You will use this dive tank for breathing underwater.
When deciding on a scuba cylinder, divers can choose from steel or aluminum tanks.
Different Sizes of Scuba Tanks
A SCUBA tank is measured in cubic feet with a standard size of 80 cu ft.
However, you can purchase a steel cylinder in various sizes, such as 3, 5, 7, 9, 10.5, 12.2, 15, and 18 liters.
When choosing between steel and aluminum scuba tanks, it’s vital to consider dry weight and size, as these can affect your buoyancy and overall comfort.
In scuba diving, dry weight refers to how much a tank weighs on land—and you’re going to want to consider if you plan on lugging your tank around when you’re not in water.
Steel is more robust and durable than aluminum, so tanks made with the latter usually have thicker walls to compensate for the reduced tensile strength.
