1st Stage

  • 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.
  • 2 HP ports
  • Protection from impact damage

2nd Stage
