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.
