Apeks XL4+ STAGE3

First 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.

• With 2 HP ports and 4MP ports.

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

• Large heat exhanger to improve cold water preformance and freezing resistance. 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.

• UV inhibitors to help prevent discolouration of the white materials.
