APEKS XL4 DIN 1st Stage Regulator

The Apeks XL4 is especially well-suited for the technical exploration diver who prefers cold water climates. Compact and lightweight, it helps reduce jaw fatigue during long, cold dives. Designed with an innovative, over-moulded endcap in conjunction with the environmental diaphragm that helps prevent ice build-up. The XL4 makes an ideal stage regulator and is also an excellent high-performance option for the technical exploration diver who is serious about maximizing functionality and minimizing weight. Features: - 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. second 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 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.
