Features:

1st Stage

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

  • Break through, innovative over-moulded first-stage endcap and environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first stage from impact damage.

  • Large surface area heat exchanger diaphragm clamp helps increase the gas temperature inside the first stage, resulting in improved cold water performance.

  • 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.


2nd 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.
