The scuba tank is the most important part of your scuba gear and contains all the air you’ll need while underwater. Unlike the freediver who goes under for a few minutes at most on a single breath, the scuba tank allows you to stay submerged for hours on end, and explore in comfort as you are totally relaxed. The ideal scuba tank must be able to withstand the immense pressure changes, should contain as much air as possible, and should be highly durable.

Scuba Tanks Buying Guide
Air supply underwater is not a matter to be taken lightly, since the life of the diver directly depends on it. A reasonable amount of consideration should be taken before you decide on the right scuba tank for you.
Our buying guide does justice to the best scuba tanks on the market that boast of great value for money and have proven to be dependable. We then take it a step further and outline the important consideration you should make when considering a scuba tank before you make a purchase.
The most common dive tanks are made from either steel or aluminum. It is important to deliberate on which of the two metals you want your tank to be made up off. Generally, steel is heavier than aluminum, and this means that steel tanks are likely going to be heavier than their aluminum-made counterparts.
Also, aluminum is highly corrosion-resistant. This is not the same for steel. When exposed to moisture for a long while, steel often begins to corrode, and this corrosion is often faster if the moisture is from saltwater.
Finally, aluminum tanks are often heavy at the bottom to aid the tanks to stand upright. However, steel is often uniform and has an even distribution of weight. So, if you buy an aluminum tank, you would likely be tail heavy when swimming.
Carbon fiber composites are becoming common in scuba tanks. They are very lightweight and can handle immense pressures. However, they are very expensive and only ideal if you don’t mind the extra cost for low weight.
Pressure Rating and Volume
These two factors are very important when scouting a perfect scuba tank. Generally, higher pressure tanks of the same size have greater volume capacities than lower pressure tanks. The volume capacity of your tank measures how much air it can store for you.
Among the best scuba tanks, it is not unusual to see a tank having a volume of up to 80 cubic feet. Also, high-pressure tanks can withstand pressures as high as 4500 psi (310.26 bar). The pressure ratings work hand in hand with the specified volume for the amount of air stored.
The higher the pressure rating and volume, the better. However, a tank that can withstand higher pressures and comes with a higher volume will consequentially be heavier.
