1. Stage - Halcyon H-75P
Halcyon's H-75P offers many refined features that ensure consistent delivery with performance that is among the very best in our industry. The stable intermediate pressure provides precise supply 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 almost any tank pressure and within almost any water temperature.
An air balanced flow piston delivers an optimal amount of air to your second stage and remains unaffected by changes in tank pressure. Lightweight and responsive components create quick adjustments to the breathing requirements that may exist under all conditions, temperatures or tank pressure. Enjoy the smoothest regulator whether you are in the final hours of an extreme caving or on a blue water ascent after a magnificent Grand Cayman wall dive.
Five hi-flow, low-pressure ports allow you to customize your hose routing for comfort and convenience. Halcyon's H-75P's 360 degree rotatable part has hi-flow ports which ensure the best possible air supply with up to 15% more air than other LP ports.

2. Stage Inkl. Octopus - Halcyon Halo
Breathing underwater should feel natural, Halcyon's second stage offers stability, reliability and impeccable performance. Two methods of breathing adjustment make it the best choice for demanding Halcyon divers.
Balanced, downstream valve provides incredibly smooth breathing in all conditions. The design slightly offsets the force of the downstream air entering from the first stage, allowing for reduced spring tension and a reduced inhalation resistance. The Halcyon first stage is balanced and the Halcyon Halo fits perfectly with either the H-75P or H-50D.
Adjustable breathing screw fine tune the breathing resistance which is easily accessible on the side of the second stage regulator. This allows the demanding diver to fine-tune the air supply of the second stage.
- Balanced, adjustable downstream valve.
- Adjustable breathing resistance.
- Air Control Vine (ACV).
- Compatible with 40% Nitrox.
SPG (Pressure Gauge)
Halcyon pressure gauges (SPG) are as reliable as they are accurate. We start with an industrial-strength spring designed for pressures in excess of 5,000 psi (400 bar), high-quality materials, and a highly visible, luminescent surface that make this a common favorite among divers in all environments.
The weight and size of our Master SPG from Halcyon makes it suitable as a primary SPG. The large, clear display is easy to read in all diving conditions.
- Calibrated to bar (0-360) or psi (0-5500).
- Nickel-plated brass with mineral glass lens.
