This compact, streamlined second stage offers premium, reliable performance in demanding conditions and a low work of breathing. The rubber purge is protected by a cast aluminum frame with an anodized matte finish to resist abrasion and corrosion while minimizing weight. Breathing resistance can be fine tuned with an ergonomic metal knob, and with a secondary micro spring adjustment. Large heat exchanging fins reduce the risk of freezing in cold water.

• Streamlined exhaust tee and ambidextrous hose routing for sidemount use
