BCD and Regulators

The BCD and Regulators collection covers buoyancy control devices and dive regulators, the core life-support and buoyancy equipment scuba divers rely on for every dive. This includes BCDs in a range of styles and sizes along with first- and second-stage regulator sets suited to cold-water diving conditions like those found along the West Coast, where reliable performance in cold, sometimes low-visibility water matters. Because this is safety-critical gear, our in-house sales and service team can help fit a BCD correctly and match a regulator to the type and depth of diving being planned.

BCD and Regulators FAQ

What is a BCD?

A buoyancy control device (BCD) is the vest or harness that holds your tank. It lets you add or release air to float at the surface or stay neutral underwater.

Jacket or back-inflate BCD?

Jacket-style BCDs are comfortable and easy for new divers, and they keep you upright at the surface. Back-inflate BCDs put the air behind you, which makes it easier to stay level in the water and leaves your chest free. Many experienced divers prefer back-inflate models.

How do I care for my BCD?

After each dive, rinse the outside and flush the inside of the bladder with fresh water, then drain it. Store it partially inflated, out of the sun.

What does a regulator do?

A regulator lowers the high-pressure air in your tank to a pressure you can breathe. A full setup includes the first stage, your primary second stage, an alternate air source (octopus), and a pressure gauge.

What's the difference between a DIN and a yoke regulator?

These are two ways a regulator connects to a tank valve. Yoke (or INT) clamps over the valve and is standard in the US. DIN screws into the valve and is common in Europe and technical diving. Adapters are available.

How often should my regulator be serviced?

Follow the manufacturer's schedule, usually every one to two years, and have it checked any time it breathes hard or free-flows. Rinse it in fresh water after every dive, with the dust cap on.
