The Halcyon H-50D First Stage Regulator is a high-performance, environmentally sealed diaphragm regulator purpose-built for reliability in harsh diving conditions, including ice diving and contaminated water environments. Its balanced diaphragm design ensures consistent, smooth breathing and stable intermediate pressure delivery, irrespective of tank pressure or depth. The H-50D features a dry balance chamber which prevents water from entering the first stage mechanism, enhancing its robust performance in extreme cold and protecting internal components. It offers two opposing high-pressure (HP) ports, allowing divers flexibility in routing their submersible pressure gauge (SPG) or transmitter. Four stationary low-pressure (LP) ports provide ample options for hose configuration, supporting both recreational and technical diving setups, including sidemount and CCR configurations where environmental sealing is paramount. With a 300-bar DIN connection and compatibility with up to 40% Nitrox, the H-50D is a rugged and dependable choice for divers who demand unwavering performance in challenging conditions.
