Buying Guide: Things To Consider When Choose Scuba Diving Tank

For most divers, it is more convenient to rent a scuba tank than to own one. For those who wish to own their own scuba tank, there are a range of considerations to take when making the decision to purchase a scuba tank.

In buying your own scuba tank from the best diving tank you can find, here are a few things you should take into account:

Your reason for diving: The kind of diving you do and the reason for diving are important considerations in choosing whether to buy or rent your scuba tank. If you dive quite frequently but you must travel by air to get to your various dive destinations, it is better to rent your scuba tank as you are not allowed to transport scuba tanks by air. If, however, your diving is more localized, then you could go ahead and buy your own scuba tank. Also, the needs of recreational divers and technical divers are quite different. So, you may need to consider which scuba tank is right for you if you dive for fun or for business. For example, recreational divers would need a scuba tank that uses the Yoke high flow capacity valve as opposed to the technical diver whose scuba tank must accept the DIN valve.

Material – You currently have two choices when it comes to the material of scuba tanks – aluminum and steel. Depending on your circumstances, you can select either one. While aluminum scuba tanks come in a limited number of sizes, the steel scuba tank offers more options. In addition, aluminum scuba tanks are lighter but less durable than steel tanks, although steel tanks will rust faster if they are not properly maintained. In any event, your choice of scuba between aluminum and steel must relate to what you actually need. So, if you dive mainly in salt water and the aluminum tank is available in your size, then you should stick to the aluminum tank.  If your dives are mainly in fresh water, then the steel scuba tank is your best bet.

Size – The size of your scuba tank is a real consideration in two ways.  First, size also determines how much gas you will get, and second, size is directly related to your height and weight. Larger scuba cylinders carry more gas and fit the bigger diver better than small scuba tanks would. If you are a large person, it makes good sense to go for a large scuba tank as it fits better on you, as well as it allows you more gas for your dive. Most recreational divers use an eleven-liter cylinder that carries 80 cf of gas at a psi of 3000 which is sufficient for a bottom dive without the risk of decompression sickness. Smaller or younger divers would require a smaller scuba tank (say the nine-liter AL 63 scuba tank). Aluminum cylinders come in around three popular sizes, the AL 63, AL 80, and AL 100. Steel scuba tanks carry more size options than aluminum such as the 50cf, 80cf, 100cf, 117cf, 133cf, and 150cf.

The number of tanks – Depending on the kind of dives you take, you may need more than one scuba tank. If you spend a lot of time underwater and do more than one dive during a typical session, then you are better off with additional scuba tanks. You may also need more than one scuba tank if the size and gas capacity of the tank you choose is less than what you actually need.

Your dive shop can also help you make the best choice of scuba tanks that are suitable for your diving situation.

Different Types of Scuba Diving Tanks 

Scuba tanks are usually constructed with aluminium or stainless steel. You won’t see any other type on the market. While aluminium tanks are lighter, the stainless steel tanks are more durable and resistant to shocks. Aluminum tanks also do not oxidize as much as the steel tanks. Other types of scuba tanks can be placed in two categories – the high pressure and the low-pressure tanks. Most scuba tanks nowadays are made for pressures ranging from a low of 2640 psi to a high of 3500 psi (pounds per square inch). The low-pressure tanks (in the 2640 psi) include the steel tanks used by technical divers who dive on the Nitrox mix, while aluminum scuba tanks are typically rated at around 3000 psi.

How to Use Scuba Diving Tank

The first thing to note is that the air in your scuba tank is a mixture that contains around 21% oxygen and 78% nitrogen. Because the air is compressed you must be careful how you use it. Use dive tables to guide you on how deep to dive, how long to stay, and how quickly to come to the surface (to avoid decompression sickness). Ensure that your air mixture is suitable for the dive you will be taking. For dives on Nitrox, the tank should indicate how much oxygen (in percent) is in the mix and how deep is a safe dive. Research before diving with your scuba tank.

How to Maintain of Your Scuba Tank

Caring for your scuba tank is very important if you want the most of your gear for a very long time. After every dive, take the time to clean up your scuba gear including the scuba cylinder before you put them away.

Maintenance of your scuba tank and gear will prevent their failure and you won’t be put in an emergency situation as a result.

Here are the steps to properly maintain your scuba tank:

  • Rinse your scuba tank completely with fresh water to get rid of salt that causes corrosion. Rinsing thoroughly will also prevent grit from clogging the tank valve and making it harder for you to control the air supply on or off.
  • Avoid storing your cylinder when it is empty or full. Without pressure in your tank contamination will occur easily in an empty tank. A cylinder stored full will also crack eventually. It is better to keep your scuba tank upright or lying horizontally when you store it.
  • Rinse the scuba tank’s regulator completely with clean, fresh water right after your dive.
  • Finally, allow everything to dry fully before putting them away.
  • Avoid leaving your scuba equipment in direct sunlight for too long as they will fade, crack or otherwise degrade.

FAQ: Frequently Asked Question About Scuba Tank

1. How long can you dive on one tank?

The short answer is around one hour. Of course, how long you can dive on one scuba tank depends on a number of things. The size of the cylinder determines the amount of air it holds, so a larger scuba tank holds more air. Having more air, however, does not mean it will last longer as to how deep you go is another factor that makes a difference between a short dive and a lingering adventure. Your level of physical activity underwater also determines how long you stay there.

If you move around a lot, then you will use more air faster. Therefore, if the water is calm, you are using a standard size scuba cylinder, and you dive no deeper than 10 meters, then expect to be underwater for at least an hour. Otherwise, your stay underwater will be much shorter. If you are a professional and very experienced diver, you can increase your dive duration by controlling your breathing and buoyancy, as well as making very little movement underwater.

2. How much does it cost to fill up a scuba tank?

The cost to fill up a scuba tank really depends on your location and the individual dive shop you choose. Generally speaking, you might find a dive shop charging around 15 dollars to fill a tank that has the capacity of around 4000 psi. Some dive shops might also charge as low as five dollars to fill a tank. You just have to shop around to get the best value for your money.

3. How often do scuba tanks need to be tested?

To fulfill the U.S. Department of Transportation (DOT) requirements for inspections, all scuba cylinders must be inspected periodically. Two forms of testing are required. The Visual Inspection (VIP) that is carried out by an inspector that is trained to do so, and the Hydrostatic Pressure test (otherwise known as the hydro test) to be done by the US DOT at a testing facility that has been approved.

Visual inspections are conducted every year so a scuba tank that has been inspected would expire twelve months later (on the first day of the month shown on the sticker). Any hydrostatic test conducted on scuba tanks expires after five years (on the last day of the month shown). In Spain, such tests expire after three years. It is, therefore, usual when purchasing a new scuba tank to examine the visual inspection sticker for the date (month and year) it was tested.

It is acceptable for a scuba tank showing a visual inspection date less than 12 months old and a hydro test less than 24 months old to be considered recent. Before any scuba tank can be sold, it must pass the first DOT certification and the annual VIP. In addition, dive shops will not refill scuba tanks that have not been tested or has expired test dates without a new test.

3. What is the best scuba tank on the market?

For the best scuba diving tank selections in the United States, look to a small handful of companies. That is companies or manufacturers responsible for the Luxfer, Metal Impact, and the Catalina brands. This situation arose in recent years when the scuba tank market experienced significant changes owing to mergers, acquisitions, bankruptcies, and closures.

Consequently, you will find that while all these manufacturers produce products of quality (they really don’t have a choice owing to DOT standards) tanks with similar capacities are often different with regard to their dimensions, weight, finishes, and buoyancy.  You might even find differences in the combination of size and service pressure among manufacturers and distributors, so for specific combinations, you will have to look to a specific manufacturer/distributor.

It gets a little difficult to follow the various brand names which, more often than not, refer to the same tanks that have been produced using the same raw materials, workmanship, and tools. So, in the US market the options for quality aluminum scuba tanks are limited to Catalina, Metal Impact, and Luxfer and for recently made galvanized steel scuba tanks, only Faber from Italy provides these.

4. How many PSI is in a scuba tank?

Although every scuba tank is considered a high-pressure vessel, there are those designed for recreation that also includes “standard”, “low” or “mid” pressure as well. Pressure, expressed as PSI or Pound (force) per Square Inch, is wide-ranging.  Although you will find a wide selection of scuba tanks with various pressures, popular options include the low-pressure tanks (up to 2640 psi), standard pressure tanks (around 3000 psi) and high-pressure tanks (3300 up to 3500 psi).

So, the amount of air pressure in a scuba tank varies depending on the type of tank (high, mid, low pressure) you select. If your intention is to dive on Nitrox, avoid choosing aluminum tanks that are high pressure (like the 3300 psi neutral buoyancy or compact tanks or the AL 100). It is, however, OK for high-pressure steel tanks which can be filled with Nitrox to a max of 3442 psi (it depends on the service pressure of your scuba tank though).

Final Verdict

Have you found the perfect scuba tank yet? Certainly, there is no doubt as to where the best scuba diving tank options can be found. Not only are you in a better position to select from recommended scuba cylinders, you are also able to sift through the volume of information out there to find what you are looking for.

When buying your scuba tank think of the long-term benefits you will derive from owning one. Steel tanks are better for buoyancy and durability. Aluminum scuba tanks are less costly if you are on a budget.  They are also lighter to carry around. With the right scuba tank, your diving will only get better.
