FIRST STAGE: Designed to be the ultimate first stage for diving in cold water or contaminated environments. The design significantly reduces weight and size compared to the original MK19. The air-balanced diaphragm with a marine-grade chrome-plated brass body provides smooth and consistent airflow regardless of depth, tank pressure, or breathing rate. The watertight seal system prevents water and pollutants from fouling the internal mechanism. The sealed chamber is equipped with a double spring for greater compactness and reliability. Two opposing high-pressure ports allow the first stage to be positioned high or low and also provide optimal hose/transmitter routing. The rotating turret features four high-flow low-pressure ports and an axial ultra-high-flow low-pressure port to maximize hose routing options.

SECOND STAGE: The balanced valve alleviates inhalation effort at various depths and intermediate pressures. The compact and robust fiberglass-reinforced nylon casing and exhaust allow this second stage to take up minimal space in your dive gear travel bag. Metal components (including the knob and valve seat) increase resistance to freezing in extreme dive conditions. The high-flow exhaust valve reduces exhalation effort, improving overall breathing comfort. Diver-adjustable inhalation effort allows the user to fine-tune the air supply to adapt to changes in depth and water conditions and meet personal preferences. The Venturi Effect Adjustment (VIVA) lever prevents continuous air flow, even when the regulator is used as an octopus. The reversible hose attachment allows for easy adjustment of the hose position for technical diving configurations. The superflow hose features an oversized bore that allows for greater airflow with each inhalation. The ultra-comfortable orthodontic mouthpiece is easy to grip but does not inhibit airflow. CE certified in compliance with the latest European EN250A standards for all diving conditions, including diving in extremely cold water.
