APEKS XL4 2nd Stage Regulator

The Apeks XL4+ is a compact, lightweight regulator suitable for diving in all environments including cold water locations. Its design and low weight help reduce jaw fatigue on long dives. The XL4+ also makes an ideal stage regulator, perfect for the exploration diver with a large amount of equipment. Not available as a stage 3 or stage 4 set. The extra high pressure port gives the option of an additional accessory, e.g. a transmitter for a computer. Features: First Stage: - 2 high pressure ports. - 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. Second Stage: - 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. - White flexible nylon braided hose has better cold water performance than 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. - Compatible with XL4 Octopus (See page A25).
