First Stage

• Compact, solid one-piece body for robust, streamlined performance.
• Over-balanced diaphragm design: as depth increases, the medium-pressure gas in the hose rises at a rate faster than ambient pressure, improving performance at depth.
• One high-pressure (HP) port and three medium-pressure (MP) ports, all angled downward for convenient hose routing.
• Environmental dry system keeps water out of the main spring chamber to prevent ice buildup and reduce silt and contamination ingress.

Second Stage

• Pneumatically balanced for smooth, easy breathing.
• Large XTX purge buttons with two-stage progressive purge: press the side for a lower flow (useful for controlled tasks like filling lift bags) or the center for a full purge when clearing the regulator.
• Large venturi lever with soft-touch rubber grip reduces grit ingress and friction while remaining easy to locate and operate.
• Easy-to-grip opening-effort control knob for precise breathing adjustment.
• Molded parts contain an antimicrobial additive effective against MRSA, E. coli, bacteria, fungi, viruses, mould, yeast and algae.
• Silicone exhaust valve to improve breathing performance.
• Comfo-bite™ mouthpiece designed to minimize jaw fatigue.
• Patented heat exchanger surrounds the valve mechanism to dissipate cold from gas expansion while drawing in ambient water warmth.

Maximum working pressure: 300 BAR (4350 psi).
