No matter where you are diving your tank is an important part of your setup. Let’s face it, being able to breathe underwater is the thing that will keep you alive, and this is not possible without the proper tank. You can dive without a tank, and freediving is a popular water sport, but if you have not yet trained yourself to hold your breath for a long time, and want to stay under the water for more than 8 minutes, then a great scuba tank is the way to go. It is the single thing that is absolutely required and life-threatening to dive without. To get the best scuba diving tank, it is important to find one that fits you well.
The best scuba tanks will be easy to use and will supply you with oxygen when you are under the water. Scuba cylinders can be a tricky topic to navigate, but we have taken the time to gather all the information you need to make the best choice. Follow our buying guide, and you will be all set to purchase a tank which will enhance your diving experience and could save your life.
Here are our top 10 scuba tanks for 2018.
How To Choose A Scuba Tank – Buying Guide
When looking through scuba diving tank reviews you will notice how important it is to get a tank that fits your body in both size and weight. It is important to look for the following features.
The standard 80 cubic feet (cf) is the most commonly used size by recreational divers. This is what typical diving companies rent out. Opting for a larger tank, 100 cf, is an excellent option for those who consume a lot of air or who are going on longer dives. Choosing a smaller 63 cf tank is a great option for beginners or kids.
These are made using either aluminum or steel. Aluminum tanks are much more resistant to rust and start out negatively buoyant. These tanks turn more positive as the air is consumed. Steel cylinders are the sturdier of the two materials and also start out negatively buoyant. They either remain that way without air or turn towards a neutral buoyancy. This requires fewer weights to be carried.
The choice is between aluminum and steel. Aluminum cylinders are negatively buoyant at the start of your dive and positively buoyant near the end. This may sound like a good thing, but it can make stopping for safety checks harder as you will be naturally floating toward the surface of the water, and you may need weights to keep you down.
Steel cylinders stay negatively buoyant when you are in the water, so it is easier to contour your depth. Steel tanks are also more durable than aluminum, but they are also heavier.
The most popular size of tank for most divers is 80 cubic feet, but dive tanks come in a variety of sizes. When people are learning to dive, a smaller than average tank is better. It will give the larger a chance to work with a smaller tank before they move onto something which is heavier and harder to handle.
When you are looking at tanks, you should be aware of how much you can carry, and also your height. Longer tanks can be unwieldy for shorter people. You also want to think about how much oxygen you need. The more you have, the longer you can dive.
There are a few accessories which you can add to your scuba tank to protect it and to make it easier to use. A cylinder boot will give the bottom of your cylinder a flat surface to sit on and will ensure that it does not get any knocks or bumps from being knocked over. A mesh protector sleeve will protect the outside of the cylinder and will protect from impacts.
Valve covers help to protect the weak point on your cylinder. They help to keep dirt and water out of your cylinder. They also protect the valves from damage; keeping the oxygen contained. You can also add handles and carriers to your cylinder to help in the transport of your cylinders to and from the water. We also recommend having a compressed gas cylinder sticker on your vehicle when you are transporting your scuba gear.
Low Or High Pressure
A high-pressure tank can hold more oxygen. They allow for a higher capacity at a smaller size. The downside is that they are a lot heavier and harder to wield. They also have to be specially filled.
Many novice divers will only need the most basic scuba tank, but as you become more experienced, you may change the way in which you dive. Some divers like to dive with a high concentration of oxygen (20.9% is standard), and you can only do this with special equipment. The valve and the tank need to be compatible. The tank needs to be cleaned and serviced by a trained professional, and the filling of the tank needs to be done by a professional too.
Q: Should I Buy Steel Or Aluminum Dive Cylinder?
A: Steel cylinders are tougher than aluminum. They can take more impact while protecting the oxygen inside. The downside of steel cylinders is that they are heavier than aluminum. Both types will do the job for you, but you need to know where you are diving to make the best choice of cylinder.
Steel cylinders are galvanized to prevent rusting and the toughness of the material allows them to withstand up to 300 bar of pressure. Aluminum cylinders will not add a lot of weight to your diving equipment, but they can only withstand up to 232 bar of pressure.
Q: What Size Cylinder Do I Need?
A: There are a variety of sizes available, and the choice will come down to many actors. Obviously, the more oxygen you have available, the longer you will be able to dive, so if you are planning on being in the water for long periods of time, then you should go for a larger capacity. The downside of a large cylinder is that it is heavier. You should ensure that you are able to carry a large cylinder before you purchase one to dive with. The other thing to think about is the pressure of the water. Some cylinders cannot withstand a lot of pressure, so you may have to stay in shallower waters even though you have a large-capacity tank.
Q: Should I Buy A 232BAR Or 300BAR Cylinder?
A: Higher pressure means move volume inside your cylinder, but it also means a heavier cylinder. If you can get more oxygen in, then there is more weight. Cylinders which can handle more pressure also have more material to do so. Both cylinders may look alike, but the 300 bar cylinder will have thicker walls so it will be heavier.
Q: What Type Of Cylinder Valve Do I Need?
A: DIN valves are used for professional diving and can be used for 232 or 300 bar cylinders. A DIN valve is more secure and will keep your tank pressurized when you are under the water. An A-clamp valve is used for recreational diving and will only work with 232 bar cylinder.
Q: Do I Need A Cylinder Boot?
A: A cylinder boot will give your cylinder something to stand on when you are not using it. It connects to the bottom of your cylinder and gives it a flat surface to rest on instead of a rounded one. You do not need a cylinder boot, but we would recommend having one to prevent your cylinder from knocks and bumps.
Q: How Many Tanks Do I Need?
A: If you are buying a smaller tank, then you can double them up so you would want to buy twice as many. We would recommend having double the tanks you need for diving. If you are wearing one tank, then have two, so that you have a spare to switch to when one runs out. If you are doubled up, then have four tanks for the same reason.
