Apeks XL4 DIN

Product description Apeks XL4 DIN

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.

- 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.
