If you already have a full set of scuba gear aside from a tank, you’ll know the hassle of calling a dive shop for reservation, picking them up and returning them back after the dive.

In this guide, we’ll reveal the best scuba tanks on the market and cover some things to think about before you buy a scuba tank.

Having your own scuba tank gives you the liberty to focus and fully enjoy your diving adventures without worrying or spending time coordinating, picking up, and sending back scuba tanks. With your own scuba tank, all you need to do is just have it air filled.

1. Catalina Aluminum Tank with Pro Valve

Material: Aluminum
Sizes: 10.2L and 12.9L

Considered as a mainstay in the compressed gas industry, Catalina is one of the bestselling brands in the scuba tank category. This scuba tank is made from aluminum and is commonly used as a primary tank.

Catalina aluminum tanks use a K Pro Valve which is one of the highest flow cylinder valves available in the market. The valve is convertible from yoke to DIN courtesy from its easy to remove 200 bar DIN insert which now allows you to use regulators with DIN 1st stage.

Catalina Aluminum tanks that are used as primary tanks come in two sizes: the 100ft3 (12.9L) or the 80ft3 (10.2L). While the 100ft3 (12.9L) is heavier than the 80ft3 (10.2L), both sizes are positively buoyant when empty.

Things to Consider when Choosing the Best Scuba Tank

At a glance, scuba tanks may look the same and you may think your choices are few. When you look further into tank selection, they can vary depending on your needs.

Here are some factors to consider in selecting the right scuba tank for you.

Valve: DIN or Yoke

All scuba tanks are sealed with a tank valve. There are two types of valves: Yoke valve and DIN valve.

Before, yoke valves were mainly used in the United States while DIN valves were the mainstay of its European counterparts. But now because of the availability of either a valve adapter or a 1st stage regulator adapter, you can find both types all around the world. Both valve types use an o-ring to provide a tight seal from the tank valve to the first stage regulator

Material: Steel or Aluminum

If you started diving in the 70’s or 80s, then you have probably dived with a steel tank attached to your BCD. But as material innovation in diving equipment evolved, aluminum tanks now dominate the scuba tank market. But this doesn’t mean that steel tanks are obsolete.

Steel tanks still exist, especially for those who want the tank to act as a complement to lead weights–steel tanks are negatively buoyant during the entire dive. Meanwhile aluminum tanks slowly become positively buoyant as the air inside is consumed.

Size

Scuba tanks come in different sizes and they are not differentiated according to small, medium, or large. Scuba tank sizes are expressed in volume or their capacity to hold compressed gas like air. The unit used is either in cubic feet (imperial) or in liters (metric).

Generally, the higher the volume, the greater the amount of compressed gas it contains. The standard scuba tank you see in dive shops are the 80ft3 or 10.2L. But having your own scuba tank allows you to choose higher volume capacity like 120ft3 or 15.3L. You can also equip yourself with back-up scuba tanks with a lower volume capacity, like pony bottles.

How to Care for a Scuba Tank

It’s important to follow safety practices when handling high pressure cylinders (scuba tanks).

First, do not leave any scuba tank standing. Always place the scuba tank down to the ground when not in use.

Second, do not attempt to change and fit unrecommended valves or use the non-prescribed valve to 1st stage regulator adapters.

And lastly, do not forget that all scuba tanks are subjected to a visual inspection once a year and a hydrotest every five years by a certified technician in an authorized service facility.
