Halcyon H-50D First Stage Regulator

The Halcyon H-50D First Stage Regulator is engineered for reliable, smooth performance in demanding diving conditions. Its balanced, environmentally sealed diaphragm design ensures consistent air delivery at various depths and tank pressures.
The dry balance chamber prevents water intrusion, making it ideal for cold water or contaminated environments.

Equipped with two high-pressure ports and four low/intermediate-pressure ports (including high-flow options), the H-50D offers excellent hose routing flexibility for different setups.
The 300-bar DIN connection is compatible with up to 40% Nitrox, making it suitable for recreational, cold-water, and technical diving.
