Halcyon’s H75P first stage (DIN) and the Halcyon Aura second stage are the center of this regulator set. In addition, you get the Aura Octopus secondary second stage and a free termo SPG as well.

Get the most out of your diving with Halcyon's air-balanced flow-through H75P piston first stage. The H75P delivers a steady air flow to your second stage unaffected by remaining tank pressure. Suitable for all dive conditions from tropical waters to arctic cold water dives. It offers you two opposing high pressure ports and five high-flow low pressure ports on the Halcyon 360 degree swivel turret cap. You cannot ask for more flexibility!

The simple and compact design of the Aura second stage makes a perfectly reliable regulator without confusing or unnecessary features. A classic downstream valve will always ensure reliable performance, regardless of the tank pressure. Enhanced breathing performance is ensured by the Air Control Vane, a diver adjustment to fine-tune your breathing according to your dive style. On top, you get a super comfortable mouthpiece that reduces fatigue of your jaw.
