If you regularly dive in extreme conditions, e.g., freezing cold waters, then this combination is perfect for you. Included are the Halcyon H75P first stage, the Halcyon Halo second stage, an Aura Octopus and a free SPG. Everything you need to jump straight into your next dive adventure.

The H75P is an air-balanced flow-through piston first stage, designed for diving in harsh environments. Optimal air flow is guaranteed, regardless of the remaining tank pressure, depth, or temperature. The two opposing high-pressure ports and five high-flow low pressure ports are placed on the Halcyon 360 degree swivel turret cap for your ultimate flexibility in hose routing. A super comfortable solution for several different set-ups depending on your dive style and personal preferences.

 Halcyon’s Halo is the perfect choice for a second stage to complete your cold water equipment. It is a balanced downstream valve, providing a smooth breathing performance in all environmental conditions. It features an adjustable inhalation control and the Halcyon Air Control Vane (ACV). With these installations, you can effortlessly fine-tune your breathing. You also have Halcyon's comfort mouthpiece for a super relaxed and comfortable dive.
