Halcyon H-50D First Stage
The H-50D is a high performance diaphragm design that is fully sealed and purpose built for harsh conditions like ice or environmentally contaminated environments.Diaphragm first stages are historically popular with cold water divers and the H-50D was engineered for extreme conditions. Go dive extraordinary places with your H-50D and be confident that you have a rugged regulator that will meet all your demands.
Balanced, environmentally sealed diaphragm provides better performance in cold water than any other diaphragm regulator while supplying consistent performance at varying tank pressures and depths; you will enjoy smooth, easy breathing throughout your dive. The dry, balance chamber, diaphragm design prevents the entry of water into the first stage mechanism and enhances a trouble-free operation; this is true even in the coldest conditions.
Two opposing high pressure ports allow you to choose where to route your SPG and allows the use of accessories. Most Halcyon diver’s route their pressure gauge to the left but the Halcyon H-50D allows flexibility with any configuration you choose; these options provide freedom to support personalized and advanced hose routing configurations.
Four low pressure ports allow you to customize your hose routing for comfort and convenience. The H-50D features four stationary low pressure ports with high flow options, ensuring the best air delivery with up to 15% more air than other LP ports. For maximum freedom, try the H-75P with its 360 degree swivel turret.

Halcyon Aura Second Stage
Halcyon Aura second stage regulators provide a simple, compact design that makes breathing under water feel completely natural. This high quality second stage delivers air in a smooth, dependable fashion.
Halcyon’s Aura second stage comes with a single adjustment control and a pre-set inhalation effort that suits most common diving situations; this feature makes it a common selection as a backup regulator.
The Aura is an ideal regulator for divers who want a simple, ready to dive regulator; it is also a common choice for training systems and rental units.
Classic downstream valve style regulators have an impressive safety record and are commonly accepted as an extremely reliable design. Part of their reliability results because the downstream valve opens in the same direction as the incoming airflow; a spring counteracts the force of the incoming air. In this design a small inhalation is required to overcome the spring tension and open the valve. This spring pressure is adjusted at the factory and allows easy breathing and consistent performance.
Air Control Vane (ACV) offers a second diver adjustment for the ability to fine-tune breathing. The ACV uses vacuum assist technology to reduce work of breathing and increase diver comfort. This level of refinement is available on all Halcyon second stages. ACV in “dive” position gives powerful breathing support while ACV in “Halcyon” position helps prevent free flows; this can be helpful on the surface, when diving in currents, while scootering, or when the Aura is used as a backup regulator.
Comfort mouthpiece is standard on every second stage to reduce jaw fatigue and mouth irritation. This long lasting mouthpiece requires only a minimum effort to hold comfortably in place. In combination with the freedom of head movement provided by Halcyon’s primary long hose, you will enjoy dives free from the jaw fatigue common with certain mouthpieces and/or poorly balanced hose routing.
