Types of Scuba Tanks: A Guide to Scuba Gear

Scuba Cylinder Tanks 

Scuba cylinder tanks, an essential part of your scuba gear, come in two main materials: steel and aluminum. Here’s what you need to know about each type:

Steel Scuba Tanks:

• High Pressure Tanks: Can be filled up to 3442 psi.
• Low Pressure Tanks: Fill up to 2640 psi.
• Advantages: Steel tanks are heavier, requiring less weight on your weight belt. This balanced weight can be beneficial for many divers.
• Sizes: Divers Direct offers Blue Steel scuba tanks in 80, 100, and 133 cubic feet. The 133 cubic feet tanks are ideal for technical divers doing deep dives, while the 100 cubic feet tank is a popular choice among recreational divers due to its capacity and manageable size.

Aluminum Scuba Tanks:

• Standard PSI: Typically hold 3000 psi.
• Advantages: Aluminum tanks are lighter and more resistant to rust, but they tend to be bottom-heavy, which can affect your buoyancy underwater.
• Sizes: Common sizes include 40, 50, 63, and 80 cubic feet, with the 80 cubic foot tank being the most popular among recreational divers.

Choosing the Right Scuba Cylinder

When selecting a scuba cylinder, consider the following:

• Air Consumption: Larger divers or those who consume more air will need larger tanks.
• Diving Frequency: Frequent divers may prefer owning their tanks, while occasional divers might find renting more convenient.
• Diving Type: Choose a tank size that suits your diving depth and frequency. Recreational divers typically use 80 cubic foot tanks, while technical divers might need 133 cubic foot tanks.

Maintaining Your Scuba Tank

Proper maintenance is crucial for the longevity and safety of your scuba gear:

• Pressure Maintenance: Keep at least 200-300 psi in your tank to prevent moisture from entering and causing rust.
• Storage: Store tanks in a cool, dry place and handle them carefully to avoid dents and scratches.
• Inspections: Get an annual visual inspection (VIP) and a hydrostatic test every five years by a certified technician.

Scuba Tank Accessories

Enhance your scuba gear with the following accessories:

• Valve Covers: Protect your tank valve when not in use.
• Tank Boots: Help your tank stand upright and protect the base.
• Carry Handles: Make transportation easier.
• Tank Racks: Keep your tanks secure during transport.
• Spare O-rings: Essential for maintaining a proper seal on your tank.
