This complete Halcyon Stage Regulator Set pairs Halcyon’s environmentally sealed H-50D first stage with a smooth breathing Halcyon Halo second stage. The set comes complete with a stage regulator hose.
Halcyon Stage Regulator Set includes
- Halcyon Halo second stage
- Halcyon H-50D first stage (DIN)
- 40″ (100cm) rubber stage regulator hose
Halo Second Stage
The Halcyon Halo second stage offers steadfast reliability and impeccable performance; two methods of breathing adjustment make it the top choice for demanding divers.
The Halo provides amazingly smooth performance in all conditions providing unsurpassed performance with enhanced technology.
Breathing underwater should feel natural, and that experience is one of the things that most clearly separates Halcyon’s second stages. You will be hooked as soon as you experience the smooth, high volume of air delivered by a Halo.
Balanced, adjustable downstream valve
Balanced, downstream valve offers incredibly smooth breathing in all conditions. The design slightly offsets the force of the downstream air entering from the first stage, allowing reduced spring tension and a decreased inhalation resistance.
Adjustable inhalation control
Adjustable inhalation control refines breathing effort through an easy access control knob; this allows the demanding diver to fine-tune the second stage’s air delivery.
Air Control Vane
Air Control Vane (ACV) offers a second diver adjustment for the ability to fine-tune breathing. The ACV uses vacuum-assist technology to reduce the work of breathing and increase diver comfort.
This level of refinement is available on all Halcyon second stages. ACV in the “dive” position gives powerful breathing support, while ACV in the “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.
Comfortable mouthpiece
Comfort mouthpiece is standard in every second stage to reduce jaw fatigue and mouth irritation. This long-lasting mouthpiece requires only a minimum effort to hold comfortably in place.
Combined 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.
- Compatible with 40% Nitrox (outside the EU)
- Adjustable downstream valve
- Air Control Vane
Halcyon H-50D First Stage
The Halcyon H-50D first stage is a high-performance diaphragm design 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 Halcyon H-50D was engineered for extreme conditions.
Dive into extraordinary places with your H-50D, and be confident you have a rugged regulator to meet all your demands.
Environmentally sealed
The balanced, environmentally sealed diaphragm first stage performs better 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 water entry into the first stage mechanism and enhances a trouble-free operation; this is true even in the coldest conditions.
First stage ports
Two opposing high-pressure ports allow you to choose where to route your SPG and allow the use of accessories.
Four low-pressure ports allow you to customise 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.
- Balanced, sealed diaphragm
- Dry balance chamber
- 2 x High-pressure Ports
- 4 x Low-pressure Ports (3/8)
- 300-bar DIN, compatible with 40% Nitrox
