Apeks XL4 OCEA STAGE 3 Dive Regulator + Octopus

First Stage

• 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

Second Stage

• 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, over moulded 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
