The Halcyon Aura second stage is a classic downstream valve in a compact and simple design. No unnecessary gimmicks, which is partly what makes this reg so reliable. It is a high quality second stage delivering air consistently. The breathing experience can only be described as smooth and dependable.
The Aura also features an Air Control Vane (ACV). With the ACV you can fine tune your breathing according to your personal needs. In ‘dive’ position, it provides a powerful breathing support. In ‘Halcyon’ position it prevents free-flows or loss of air, when using it as a back-up regulator.
