Features:

1st Stage

• Breakthrough, innovative over-moulded first-stage endcap and environmental diaphragm help 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 1st 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

• Compact machined 1st stage based on the expedition tested Apeks DS4 platform.

2nd Stage

• Compact and lightweight 2nd 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 traditional rubber hose

• Standard metallic hose connection for interchangeability

• Comfo-biteTM 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.
