  • First stage

    • BALANCED DIAPHRAGMProvides superior and consistent performance.
    • BLUE HIGH PRESSURE SEATIt is the core of the first stage. The Blue High Pressure Seat opens and closes with every breath, forming a perfect seal with durable materials that work in all conditions and with all gasses. The working pressure of the first stage is automatically elevated to counteract the increased breathing air density.
    • DUST CAP PROTECTIONAttached to the regulator body, the Dust Cap protects the inlet fitting and the Auto Closure Device from impacts and damage. It also seals the first stage when it's off the tank.
    • HIGH PRESSURE/MEDIUM PRESSURE PORTSHP and MP ports and "T" Shape o 2 HP ports (7/16”) and 4 MP ports (3/8”) perfectly oriented in a “T” shape for streamlined hose positioning.
    • AVAILABILITYDIN (4,350psi/300 bar max.) and YOKE (3,300psi/232 bar max.).

     

    Second stage

    • COVER OPENING CHANNELSThe Front Cover Opening Channels allow water to flow sideways over the diaphragm. The wide radial openings prevent freeflows when diving in strong currents and reduces cracking effort by 20%.
    • VENTURI ADJUSTMENT SWITCHThe Venturi Adjustment Switch allows divers to precisely control and adjust the air flow. In the “MIN” position, the valve's assistance is minimized, resulting in a higher inhalation effort, ideal to avoid freeflow. In the “MAX” position, the valve's assistance is maximized, resulting in a lower inhalation effort. The overmolded elastomer and ergonomically designed lever allow control of the air flow even while wearing gloves.
    • COMFOBITEA patented and comfortable mouthpiece featuring a unique palate bridge reduces jaw fatigue and securely holds the second stage in place. Made from hypoallergenic silicone, the orthodontic mouthpiece is both soft and sturdy.
    • INTERCHANGEABLE MOUTH PIECEThe detachable and reusable mouthpiece clamp allows for quick and simple tool-free change, avoiding plastic waste.
    • REUSABLE MOUTHPIECE CLIPPerform quick and easy mouthpiece changes using the removable, reusable clip.
    • BRAIDED HOSEProvides flexibility, comfort and excellent transportability.
