Over-balanced First Stage
Break through, innovative over-moulded first-stage endcap and environmental diaphragm help to prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the Apeks XL4 First Stage Regulator from impact damage.
The large surface area heat exchanger diaphragm clamp helps increase the gas temperature inside the first stage, improving 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.
