Tanks

This collection features XDEEP backplate and wing systems built around how you carry your tanks. The ZEOS line is designed for single-tank diving and comes in Standard, Comfort and Deluxe versions with 28 lb or 38 lb wings. The HYDROS 40/50 DIR sets are built for divers running double tanks.

A backplate and wing gives you a stable, streamlined position in the water, and you can add or swap parts as your diving changes. Wing size should match your tank and exposure suit. A smaller wing works for a single aluminum tank in a wetsuit, while doubles and drysuits call for more lift.

Our Montclair, CA staff can help you dial in harness fit and trim. For other buoyancy options, see BCDs and sidemount systems, and pick up cam bands and tank accessories for your setup.

    Scuba Tank Buying & FAQ

    Find the right air cylinder for your dives. Read our scuba tank buying guide and common FAQs below.

    Scuba Tank Buying Guide

    1. Choose between aluminum and steel tanks. Aluminum tanks are more common and lighter when empty, while steel tanks offer higher capacity and better buoyancy characteristics.
    2. Select the right size and capacity. Tank size affects how much air you have available and how long you can stay underwater.
    3. Check working pressure. Higher pressure tanks can hold more air but may require compatible regulators and fill stations.
    4. Consider valve type. Yoke valves are standard in many regions, while DIN valves offer a more secure connection for higher pressure systems.

    A scuba tank is a high-pressure cylinder that stores compressed air or gas used by divers during a dive.

    The duration depends on tank size, depth, and breathing rate, but most recreational dives last between 30 to 60 minutes.

    Aluminum tanks are more widely used and cost-effective, while steel tanks offer higher capacity and improved buoyancy characteristics.

    Scuba tanks require regular visual inspections and periodic hydrostatic testing to ensure safety and compliance.

    Traveling with tanks is possible but often requires them to be empty and inspected, and many divers prefer renting tanks at their destination.

    Standard scuba tanks are typically filled to around 3,000 psi, though high-pressure tanks can hold more.

    Owning a tank is optional, as many divers rent tanks, but owning one offers convenience for frequent divers.

    Key features include capacity, material, working pressure, valve compatibility, durability, and suitability for your diving style.
