First Stage

Travel-ready, compact first stage designed to protect internal components and provide consistent, low-effort breathing in a variety of diving conditions.

• Auto Closure Device (ACD): keeps the inlet closed when not connected to a cylinder to protect internal parts, help maintain oxygen compatibility, preserve internal lubrication, and keep the inlet filter clean and dry.
• Permanent Dry Chamber: isolates internal parts from external moisture to reduce icing and enhance cold-water performance.
• Over-balanced (auto-balanced) mechanism: compensates interstage pressure to reduce breathing effort and deliver consistent performance regardless of depth or tank pressure.
• Balanced diaphragm: provides superior, consistent performance.
• Blue high-pressure seat: durable sealing seat that opens and closes with each breath; working pressure is automatically elevated to compensate for increased breathing gas density.
• Dust cap protection: attached cap protects the inlet fitting and ACD from impacts and seals the first stage when removed from the tank.
• Ports: 2 HP ports (7/16 in) and 4 MP ports (3/8 in) arranged in a T shape for streamlined hose positioning.
• Availability: DIN (4,350 psi / 300 bar max) and Yoke (3,300 psi / 232 bar max).

Second Stage

Compact, low-profile second stage optimized for smaller faces and long dives, offering adjustable breathing control and comfort features.

• Cover opening channels: wide radial openings direct water sideways over the diaphragm to reduce freeflows in strong currents and lower cracking effort by about 20%.
• Venturi adjustment switch: selectable MIN (minimized valve assistance to avoid freeflow) and MAX (maximized assistance for lower inhalation effort); ergonomically designed lever with overmolded elastomer for gloved use.
• Cracking effort adjustment: fine-tune breathing performance to suit different diving conditions.
• Pneumatically balanced: ensures smooth, easy breathing at all depths.
• Heat exchanger: helps prevent ice formation on the valve inlet.
• Compact design: suitable for smaller faces, preserves field of vision, and reduces jaw fatigue.
• Comfobite mouthpiece: patented palate bridge reduces jaw fatigue and helps retain the second stage; made from hypoallergenic silicone.
• Interchangeable, reusable mouthpiece clip: allows quick, tool-free mouthpiece changes to reduce plastic waste.
• Braided hose: provides flexibility, comfort, and improved transportability.

Summary: A travel-friendly regulator set with protective first-stage features for cold-water use and a compact, comfortable second stage with adjustable breathing controls.
