Halcyon Regulators



Halcyon Regulators are extremely reliable and have been used on the longest scuba dives ever accomplished and in some of the harshest conditions; such as the deep wrecks of the Baltic Sea and in the high altitude caves of the Russian interior.

The Halcyon H75-P and Halcyon H50-D offer piston or diaphragm first stage options with the Halcyon Halo and Auro downstream second stages. All Halcyon regulator systems are CE approved for 4300psi cold water diving and exceed the CE cold water requirements. To further reduce the risk of regulator freezing in cold conditions, Halcyon's H-50D uses a dry ambient pressure chamber. Meanwhile, Halcyon second stages feature precision molded carbon fiber and technopolymer valve housing and components which also contribute to their lightweight features and corrosion resistance.

Halo-1_webHalo 2nd Stage The Halo provides amazingly smooth performance in all conditions providing unsurpassed performance with enhanced technology.

  • - Balanced, adjustable downstream valve
  • - Adjustable control knob refines inhalation resistance
  • - Air Control Vane (A.C.V.) utilizes vacuum power to reduce work of breathing
  • - Compatible with 40% Nitrox (outside EU)

H75-P_webH-75P First Stage The unsurpassed performance of this first stage results from a balanced piston design which delivers significantly more gas than any other first stage design while leaving performance completely unaffected by changing tank pressure. - Balanced, flow-through, freeze-resistant piston provides high performance - Rotating swivel provides flexibility and super clean hose routing - Two high pressure ports, five High Flow intermediate/low pressure ports - 300 bar DIN, compatible with 40% Nitrox (outside EU)

Aura 2nd Stage Aura 2nd StageStrong performance and a simple, non-adjustable design make the Aura an ideal reserve and/or recreational regulator. - Non-adjustable downstream valve - Air Control Vane (A.C.V.) utilizes vacuum power to reduce work of breathing - Compatible with 40% Nitrox (outside EU) H-50D First StageH-50D First Stage This balanced, environmentally sealed diaphragm provides premium performance and rock solid protection in the absolute worst environmental conditions. - Balanced, environmentally sealed diaphragm - Dry balance chamber ensures solid performance in the worst conditions - Two high pressure ports, four intermediate/low pressure ports - 300 bar DIN connection, compatible with 40% Nitrox (outside EU)
