Complete Stage Regulator Set with Halcyon balanced H-75P 1st Stage with non-adjustable Halcyon Aura 2nd Stage comes with 102cm regulator hose.
Additional SPG and 15cm Hose can be added
Halcyon H-75P First Stage:
Halcyon's H-75P offers many refined features that ensure consistent delivery with performance that ranks among the very best in our industry. The stable, intermediate pressure provides precise delivery of air 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 you are on the final hours of an extreme cave exploration or on a blue water ascent after a magnificent Grand Cayman wall dive.
- Five High-flow, Low-pressure Ports allow you to customize your hose routing for comfort and convenience. The Halcyon 360 degree swivel turret cap with high flow ports ensure the best air delivery possible with up to 15% more air than other LP ports. Combined with Halcyon's "long" primary hose and backup necklace your hoses can be configured where you need them. 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.
- Two opposing high pressure ports allow you to choose where to route your SPG and allows the use of accessories. Most Halcyon divers route their pressure gauge to the left but the Halcyon H-75P allows flexibility with any configuration you choose; these options provide freedom to support personalized and advanced hose routing configurations.
- 300 Bar DIN first stage is the most secure connection available; our DIN fittings are compatible with a wide range of yoke conversion kits.
- Nitrox 40% compatible right out of the box so you can start diving without any additional concerns. Assemble your system, analyze your gas and go diving. We also offer Oxygen clean upgrade kits for the H-75P so you can enjoy these great features on all your deco bottles.
- Externally adjustable intermediate pressure allows a quick fine-tuning by a Halcyon service technician without fully disassembling the first stage.
Halcyon Aura Second Stage with 102cm Hose:
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. Your Authorized Halcyon Service Technician can make any desired adjustments.
- 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.
