Halcyon Aura Second Stage Regulators: A Simple, Reliable Breathing Solution
The Halcyon Aura Second Stage regulator is designed for divers who value simplicity and reliability. Its compact design ensures breathing underwater feels natural, while delivering air smoothly and consistently.
Ideal for Various Diving Situations
Halcyon’s Aura second stage features a single adjustment control and a pre-set inhalation effort suitable for most common diving conditions, making it a popular choice as a backup regulator.
This regulator is perfect for divers seeking a straightforward, ready-to-dive second stage. It is commonly used in training systems and rental setups as well.
Classic Downstream Valve for Proven Safety
The Halcyon Aura employs a classic downstream valve, known for its exceptional safety and reliability. This design has a long history of performance, as the valve opens in the same direction as the incoming airflow. A spring counteracts the force of the incoming air, ensuring safe operation.
To activate the valve, a small inhalation is required to overcome the spring tension. The spring pressure is factory-adjusted to provide smooth, easy breathing and consistent performance throughout your dive.
Air Control Vane (ACV) for Enhanced Breathing Comfort
The Aura features Halcyon’s Air Control Vane (ACV) system, which provides an additional adjustment to fine-tune your breathing. Using vacuum-assist technology, the ACV reduces the work of breathing and increases overall comfort.
When set to the “dive” position, the ACV offers powerful breathing support. In the “Halcyon” position, it helps prevent free flows, making it especially useful during surface intervals, diving in currents, scootering, or using the Aura as a backup regulator.
Comfort-Oriented Mouthpiece Design
Each Halcyon Aura second stage comes with a comfortable mouthpiece to minimize jaw fatigue and mouth irritation. This long-lasting mouthpiece requires minimal effort to keep in place, ensuring comfort throughout the dive.
Paired with Halcyon’s primary long hose, the Aura reduces the discomfort often caused by poorly balanced hoses and mouthpieces, offering a more comfortable, fatigue-free diving experience.
