Aura second stage regulators provide a simple, compact design that makes breathing under water feel completely natural. This high-quality second stage delivers air in a smooth, dependable fashion. Halcyon’s Aura second stage comes with a single adjustment control and a pre-set inhalation effort that suits most common diving situations. This feature makes it a common selection as a backup regulator. The Aura is an ideal regulator for divers who want a simple, ready-to-dive regulator. It is also a common choice for training systems and rental units.
Classic downstream valve style regulators have an impressive safety record and are commonly accepted as an extremely reliable design. Part of their reliability is because the downstream valve opens in the same direction as the incoming airflow, and a spring counteracts the force of the incoming air. In this design, a small inhalation is required to overcome the spring tension and to open the valve. This spring pressure is adjusted at the factory, and allows easy breathing and consistent performance. Your authorized Halcyon Service Technician can make any desired adjustments.
Air Control Vane (ACV) offers a second diver adjustment, for the ability to fine-tune breathing. The ACV uses vacuum-assist technology to reduce work of breathing and increase diver comfort. This level of refinement is available on all Halcyon second stages.
