Halcyon Doubles Regulator Package – H-75P First Stages + Halo Second Stages

High-Performance Breathing for Technical, Cold-Water & Advanced Diving

The Halcyon Doubles H-75P + Halo Regulator Package delivers exceptional breathing performance, flexible hose routing, and unmatched reliability—making it the ideal configuration for technical divers, cold-water environments, and demanding dive profiles. Featuring two Halcyon H-75P First Stages paired with two Halo Balanced Second Stages, this package is engineered for divers who expect precision, durability, and smooth inhalation in any environment.

The H-75P utilizes Halcyon’s balanced, freeze-resistant piston design to ensure consistent airflow even in extremely cold water. Its rotating swivel turret and progressive hose routing options provide enhanced comfort, reduced jaw fatigue, and optimal long-hose/backup configurations. With two HP ports and five high-flow LP ports, the H-75P supports a wide range of gear layouts, including technical doubles and stage/deco bottles.
Paired with the Halo’s adjustable inhalation resistance and Air Control Vane (ACV), divers experience effortless, natural breathing throughout the dive.
