Halcyon 50D Single Tank Long Hose Regulator Set

The Halcyon 50D Single Cylinder Regulator Set provides an excellent long hose setup for single-tank diving. The Halcyon H-50D first stage is paired with a premium Halo primary regulator and an Aura backup regulator. This set includes a long main hose and a short backup hose to maximise streamlining.

Furthermore, both second stages utilise an innovative Air Control Vane (ACV) with vacuum-assist technology to reduce your breathing effort. Standard comfort mouthpieces eliminate jaw fatigue entirely. Additionally, the long primary hose grants complete freedom of head movement underwater.

Halcyon Regulator Set Includes:

• Halcyon H-50D first stage with a secure 300-bar DIN fitting.
• Halcyon Halo second stage as the main regulator.
• Halcyon Aura second stage as the backup regulator.
• A 210cm (7′) rubber main hose and a 24″ rubber backup hose.

Main Second Stage – Halcyon Halo

The Halcyon Halo second stage offers steadfast reliability and adjustable inhalation control via an easy-access knob. It features a balanced, adjustable downstream valve that decreases inhalation resistance. Consequently, you receive an incredibly smooth, high volume of air.

Additionally, the integrated Air Control Vane provides superior flexible control. For instance, the “dive” position gives powerful breathing support during your dive. Meanwhile, switching to the “Halcyon” position helps prevent surface free flows.

• Fully compatible with 40% Nitrox outside the EU.
• Features an adjustable downstream valve for custom tuning.
• Includes an innovative Air Control Vane to maximise comfort.

Backup Regulator – Halcyon Aura

The compact Halcyon Aura second stage provides a reliable classic downstream valve design. It features a preset inhalation effort that suits most common diving situations perfectly, making it a popular backup choice.

Furthermore, this reliable design opens in the same direction as the incoming airflow. A factory-adjusted spring counteracts the air force, requiring only a small inhalation to open the valve. Therefore, you can count on consistent, dependable performance when you need it most.

• Highly compatible with 40% Nitrox outside the EU.
• Utilises a highly reliable non-adjustable downstream valve.
• Includes a built-in Air Control Vane to prevent free flows.

Halcyon H-50D First Stage

The high-performance Halcyon H-50D first stage features a balanced, environmentally sealed diaphragm design. Engineers purpose-built this dry balance chamber system for harsh conditions like ice or contaminated environments. Therefore, it prevents water entry and ensures smooth, consistent breathing at any depth.

Additionally, the first stage includes two opposing high-pressure ports for routing flexible pressure gauges.

• Balanced, sealed diaphragm design ideal for cold water diving.
• Features a protective dry balance chamber to enhance reliability.
• Includes 2 x High-pressure Ports and 4 x Low-pressure Ports (3/8).
• 300-bar DIN fitting.
