More Details

The Coea is the first product of its kind; it is a green regulator produced in a solar-powered plant using bioplastics and recyclable materials. The XL4+ served as the foundation for the development of the most environmentally conscious scuba diving regulator ever made. A genuinely revolutionary regulator, the Ocea removes five times as much plastic from the environment as it weighs.


✔ Compact machined first stage based on the expedition-tested Apeks DS4 platform.

✔ Unique over-balanced diaphragm design - as the diver descends, the over-balancing feature allows the medium-pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.

✔ 2 HP ports and 4MP ports

Additional Features:

Compact and lightweight second stage improves comfort and helps reduce jaw fatigue on long-duration dives.

High-performance pneumatically balanced lever-operated poppet valve.

✔ Large, molded self-flushing, and controllable purge button

Ergonomic Venturi lever is easy to use and locate

✔ Flexible nylon braided hose has better cold water performance than a traditional rubber hose

Standard metallic hose connection for interchangeability

Comfo-bite mouthpiece has a unique bridge that fits across the upper palate and does not require bite pressure to stay in place.

Re-useable mouthpiece clip makes it simple to change mouthpieces in the field

Durable and flexible rubber exhaust tee provides excellent bubble diversion.
