Halcyon Aura Octopus: A Simple, Reliable Breathing Solution
The Halcyon Aura Octopus offers a compact design that delivers natural breathing underwater. Known for its smooth and dependable performance, this high-quality second stage is an essential tool for divers.
Ideal for Backup Use in Common Diving Scenarios
The Halcyon Aura Octopus features a single adjustment control and a pre-set inhalation effort that is ideal for most diving conditions. This makes it a popular choice as a backup regulator, ensuring smooth air delivery when needed most.
Classic Downstream Valve Design for Dependability
The Aura Octopus uses a classic downstream valve, which is recognized for its outstanding safety and reliability. The design ensures that the valve opens in the same direction as the incoming airflow, with a spring counteracting the force of the incoming air for secure operation.
This setup requires a small inhalation to overcome the spring tension and open the valve. Factory-adjusted spring pressure ensures easy breathing and consistent performance, even under varying conditions.
Air Control Vane (ACV) for Enhanced Breathing Comfort
Halcyon’s Air Control Vane (ACV) provides an extra adjustment to fine-tune breathing effort. By using vacuum-assist technology, the ACV helps reduce the work of breathing, improving overall comfort.
The ACV has two positions: in the “dive” setting, it offers powerful breathing support, while in the “Halcyon” setting, it helps prevent free-flowing air. This adjustment is especially useful during surface intervals, while diving in currents, using a scooter, or when the Aura Octopus is functioning as a backup regulator.
Comfortable Mouthpiece for Fatigue-Free Dives
The Aura Octopus comes with a comfort mouthpiece, designed to reduce jaw fatigue and mouth irritation. This long-lasting mouthpiece stays securely in place with minimal effort, ensuring comfort during extended dives.
Paired with Halcyon’s primary long hose, the Aura Octopus reduces jaw strain and discomfort commonly associated with poorly balanced hoses and mouthpieces.
