How to Choose the Best Scuba Tanks?

Scuba tanks are used by every scuba diver and in every dive boat and dive shop today. The regular 80 cubic foot aluminum tank has been used by all, but scuba tanks can be found in many varied shapes and sizes. Each scuba tank comes with its own pros and cons, price tag and purpose. Here are some of the most useful tips to help you to choose the best scuba tanks.


The length and not the diameter of their scuba tank is a cause of worry for the majority of most scuba divers. If you can carry the tank by lifting it and not drag it across the deck of the boat, it is indicative that either you have short hands or are unable to carry the weight. The tank might be too long in case strength is not an issue. Some of the best scuba tanks made of steel and of high pressure variety are just 20 inches long in total size.


Aluminum 80 tanks are ubiquitous today, as these are cheap in cost. While these tanks can be found in 100, 63 and 50 cubic foot units, the 80 cubic foot tank happens to be the most famous. This is just because this is one of the first and most commonly used sizes of Aluminum tank. The first 72 cubic foot tanks with aluminum construction came with rounded bottoms, and are slightly taller in size.

Air Capacity

You should also check the tank’s air capacity. If your consumption of air is significantly less than your fellow diver, it makes no sense to carry the additional air weight back to your boat. A smaller unit of 50 cubic foot is the best choice when you are diving only with students. The best scuba tanks are those that match your own air consumption, safety considerations and diving objectives.


These tanks are typically composed of two materials – aluminum or steel. The tanks made of aluminum are cheaper in cost, and are lighter than steel tanks. However, aluminum is softer when compared to steel and are likelier to get damaged due to careless or rough handling. The best scuba tanks made of aluminum usually come with a lifespan of about 15 years than steel tanks that can last for as long as three decades. However, that is unlikely to be a big problem if you purchase a new tank.
