How to choose a diving bottle?

Choosing a diving bottle is a crucial decision when diving because it is directly related to your safety and comfort. Here are the key factors to consider when choosing a scuba tank:

The capacity of a diving bottle is usually measured in liters or cubic feet, while the pressure is expressed in bars or psi. Different diving activities may require different tank capacities and pressures, such as deeper or longer dives requiring larger capacity tanks.

When diving in the tropics, due to the high water temperature, divers generally only wear 3mm wetsuits or even jellyfish suits. At this time, it is more appropriate to choose aluminum bottles. First, because all dive shops have aluminum bottles; second, because aluminum bottles are slightly positively buoyant when empty, and we do not need to carry too much weight to maintain neutrality at a depth of 3-5 meters at the end of the dive. buoyancy. Choosing a cylinder with too much negative buoyancy may make the diver overweight and require more air in the BCD to maintain neutral buoyancy.

In addition to this, it is also very important to check the maintenance history and appearance of the diving bottle. Cylinders have been regularly inspected and maintained, and checked for any obvious signs of damage or corrosion. When purchasing second-hand gas cylinders, you should check carefully to ensure that they are safe and reliable.

Finally, the weight and comfort of the tank are also factors to consider. Diving bottles are usually relatively heavy. It is very important to choose a weight that suits your physical strength. You should also consider the comfort and stability of carrying the bottle.
