How Much Does an AL80 Scuba Tank Weigh?

September 25, 2022 2 min read

Before you buy a Scuba tank, you must consider its weight. The standard aluminum 80 tank weighs 32 pounds. You must also factor in other equipment, such as a 7mm wetsuit, regulator, and fins. Combined, these equipments add up to more than 35 pounds, so you must factor in all of the weights when you weigh your equipment. To determine the fresh water weight of an AL80 Scuba tank, multiply the weight of the tank by 0.025 and the weight of the fins by 0.35.


The AL80 Scuba Tank weighs 31.3 pounds when empty and displaces approximately 27.8 pounds of sea water. The tank can be filled to a pressure of 500 PSI. This allows for greater buoyancy and allows divers to dive deeper without getting overly dehydrated.

The AL80 cylinder is made of aluminum, and it is commonly used in the diving industry. It is a popular sling cylinder for decompression gas and a side-mount cylinder for fresh water. With an internal volume of 11 litres and a working pressure of 3,000 psi, the AL80 cylinder weighs 31.5 kilograms (66 lbs). In salt water, the AL80 cylinder weighs -1.7 pounds (771 grams) less than a steel cylinder of the same capacity.


Scuba cylinder markings can be as obscure as ancient Sanskrit, but once you get used to them, they are not difficult to understand. First, it's important to recognize which governing agency your cylinder is certified to. In the U.S., this is the DOT, while in Canada it's Transport Canada. Next, there's the material of the cylinder's construction, with steel cylinders carrying a 3AA designation, and aluminum cylinders carrying a 3AL designation. Older aluminum cylinders may also have an SP6498 designation.

Scuba cylinders weigh a different amount than other types of diving equipment, so it's important to determine the weight of your cylinder before using it. The DOT-3AL-3000 Scuba Tank weighs approximately 450 pounds, while an aluminum S63 cylinder weighs just over a thousand pounds. The weight of a cylinder varies depending on its material and size, as well as its capacity. If you want to know how much scuba dive unit weighs, read more from us.
