Originally known as the cylindrical pressure vessel, the scuba tank is one of the most vital components of your diving equipment. The diving tank is responsible for storing and transporting high pressure breathing gas. This piece of equipment is what keeps the diver alive and breathing underwater. The gas is provided to the diver through the demand valve of a diving regulator which divers put in their mouth. Common tanks used by average adults, measure up to 80 cubic feet. Other dive tanks used by teens or petite women may be less than that depending on their lung size, fitness, and other factors.
Different Types of Tanks
Diving cylinders are made in two types: Aluminum tanks and Steel tanks. There’s not much difference between the two other than the obvious fact that they are made out of different metals. Aluminum tanks are the most common in the world and since they are more cost efficient, especially compared to steel tanks, they can be found at almost any dive resort or scuba rental shops. They are much lighter than steel tanks which make it easier to carry around.
The steel tanks come in a variety of shapes and sizes. They have better buoyancy characteristics compared to aluminum tanks as they do not float at the end of the dive. You do not have to spend more effort in counter-weighting them as you would with the aluminum tanks since they are already naturally heavy. If well maintained, the steel tanks last way longer than aluminum and is said to keep working for decades.
Scuba tanks last up to years if well maintained having you save money for the other scuba equipment which you need to purchase or replace. Both types of scuba tanks can last up to ten years and over, regardless of whether it is steel or aluminum.
It easy for you to determine which tank you should use for the type of diving you are planning to do and they come in different sizes with different volume capacities and pressure designed for people with different breathing capabilities.
Since scuba tanks are made from metals, they create metal oxides in the presence of sea water which could only mean one thing: rust! Preventing rust requires a lot of proper maintenance on your tank which takes up a lot of energy and time.
Another thing to keep in mind is that the tank itself is very heavy which, and due to its sizing, makes it difficult to travel with. So unless you aren’t doing many local dives then it is best for you to just rent them.
Every scuba diver needs a scuba diving tank in any dive that involves staying underwater for a long period of time. If you’re a frequent diver then it would be cheaper for you to actually own a diving tank rather than renting one several times. Proper maintenance is all that is required to keep your tank lasting for years and years. It is easy to pick out which scuba diving tank will suit you and your bodily limits. The cost is very reasonable as the life periods for diving tanks are very lengthy. There are many deals you can find online for discounts on scuba tanks.
