Second Stage

Pneumatically balanced second stage engineered for smooth, easy breathing and precise control.

• Two-stage progressive purge: Large, easy-to-operate purge buttons — press the side for a lower flow (useful for controlled tasks such as filling lift bags) or press the centre for a full purge when clearing the regulator.
• Venturi lever: Large lever with a soft-touch rubber grip reduces grit ingress and friction and is easy to locate and use.
• Opening-effort control: Easy-to-grip knob lets the diver adjust inhalation effort.
• Infection-resistant molded parts: All molded components are produced with an additive that kills MRSA, protects against E. coli, bacteria and fungi, and is effective against viruses, mould, yeast and algae.
• Silicone exhaust valve: Improves breathing performance.
• Comfo-bite mouthpiece: Minimizes jaw fatigue for greater comfort.
• Patented heat exchanger: Surrounds the valve mechanism to dissipate cold from gas expansion while drawing in warmth from the ambient water.
