The Halcyon 50D Twinset Regulator Package is an excellent long hose setup for twinset diving. The robust Halcyon H-50D first stages are paired with a Halcyon Halo second stage as a main and Halcyon Aura as a backup regulator. The set has a long main regulator hose and a short backup regulator hose.
Both Halo and Aura second stages feature an Air Control Vane (ACV) that offers 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.
Comfort mouthpiece is standard in both second stages 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.
Halcyon 50D Twinset Regulator Package includes
- 2 x Halcyon 50-D first stages (DIN)
- Halcyon Halo second stage as a main regulator
- Halcyon Aura second stage as a backup regulator
- 210cm (7') main regulator hose (rubber)
- 24" backup regulator hose (rubber)
Main Regulator - Halcyon Halo
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.
- Compatible with 40% Nitrox (outside the EU)
- Adjustable downstream valve
- Air Control Vane
Backup Regulator - Halcyon Aura
Halcyon Aura second stage regulators provide a simple, compact design that makes breathing underwater feel 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.
Classic downstream valve style second stages 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.
This design requires a small inhalation to overcome the spring tension and open the valve. The spring pressure is adjusted at the factory and allows easy breathing and consistent performance.
- Compatible with 40% Nitrox (outside EU)
- Non-adjustable downstream valve
- Air Control Vane
Halcyon H-50D First Stages
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.
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. Most Halcyon divers 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 personalised and advanced hose routing configurations.
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
