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 overbalancing
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
• Comes standard with 2 HP and 4 MP ports
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

rubber hose

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
