Halcyon H 50D Single Cylinder Halo/Aura Scuba Diving Regulator Package - Professional Dive Gear for Underwater Exploration & Cave Diving

The Halcyon Aura Diver Regulator Set consists of a Halcyon H-50D Diaphragm environmentally sealed first stage and a Halo second stage primary and Aura second stage occy, a full Halcyon Single tank hose kit, a brass body Halcyon Master SPG plus two small stainless steel bolt snaps, a regulator necklace and a regulator bag!

Halcyon’s H50D first stage is a balanced diaphragm. It is environmentally sealed, which makes it suitable for harsh dive conditions such as extremely cold water or contaminated environments. The high-performance diaphragm design has been popular with cold water divers for quite some time.

The H50D features two high-pressure ports on opposing sides. This way you are free to choose where to attach your SPG. Together with the four low pressure ports, it gives you a lot of freedom for your preferred hose routing.

It is a 300 bar DIN fitting with a Nitrox compatibility of up to 40%.* With the correct adapter, you can also convert this first stage into a Yoke fitting.

Features:

• Balanced and environmentally sealed diaphragm
• 2 HP and 4 LP ports
• 300 Bar DIN first stage

HALO SECOND STAGE REGULATOR

Breathing underwater should feel natural, and that experience is one of the things that most clearly separate Halcyon second stages from our competitors.

Specification for Halo Second Stage:

• Balanced, adjustable downstream valve
• Adjustable inhalation resistance
• Air Control Vane (ACV)
• Compatible with 40% Nitrox
• Bench testing by an authorized Halcyon regulator service technician is recommended prior to use

The Halcyon Aura octopus is a classic downstream valve in a compact and simple design. No unnecessary gimmicks, which is partly what makes this reg so reliable. It is a high quality second stage delivering air consistently. The breathing experience can only be described as smooth and dependable.

The Aura also features an Air Control Vane (ACV). With the ACV you can fine tune your breathing according to your personal needs. In ‘dive’ position, it provides a powerful breathing support. In ‘Halcyon’ position it prevents free-flows or loss of air, when using it as a back-up regulator.

Features:

• Classic downstream valve second stage
• Air Control Vane
• Comfort mouthpiece

Halcyon pressure gauges are as reliable as they are accurate. We start with an industrial-strength spring designed for pressures beyond 5,000psi (400bar), high-quality materials, and a highly visible, luminescent face which. makes this a common favorite among divers in all environments. Pick from our Standard or Stage pressure gauges.

Specification:

• Hoses and Regulator Bag included
• LP inflator hose does not come with this package.  LP Inflator hoses are included on all Halcyon wings. 
• Bench testing by an authorized Halcyon regulator service technician is recommended prior to use
