This complete Halcyon Stage Regulator Set pairs Halcyon’s high-performance piston H-75P 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-75P 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-75P First Stage
The Halcyon H-75P first stage offers many refined features that ensure consistent delivery with performance that ranks among the very best in the diving industry.
The stable, intermediate pressure provides precise air delivery to the second stage. This means you will experience a remarkable ease of breathing while diving in all environments; this is true at nearly any tank pressure and within almost any water temperature. This sophisticated technology is among the best in the industry, freeing you to get the most out of your diving.
Air-balanced flow-through piston delivers an optimal amount of air to the second stage, remaining unaffected by changes in tank pressure. Lightweight & responsive components create prompt adjustments to breathing demands in all conditions, temperatures or tank pressures.
Enjoy the smoothest breathing regulator, whether on the final hours of an extreme cave exploration or on a blue water ascent after a magnificent Grand Cayman wall dive.
Rotating Swivel
Rotating swivel provides flexibility and super clean hose routing. The Halcyon 360-degree swivel turret cap with high flow port ensures the best air delivery possible with up to 15% more air than other LP ports.
Whether diving a sophisticated rebreather or a simple, open water system, you can create a configuration that supports easy movement, reduces jaw fatigue from ill-routed hose position and streamlines your diving profile.
Five High-flow Low-pressure Ports allow you to customise your hose routing for comfort and convenience.
Two opposing high-pressure ports allow you to choose where to route your SPG and allow the use of accessories.
- Balanced, freeze-resistant piston design
- Rotating swivel
- 2 x High-pressure Ports
- 5 x Low-pressure Ports (3/8)
- 300-bar DIN, compatible with 40% Nitrox
