Aura second stage regulators provide a simple, compact design that makes breathing under water feel completely natural.
The H-50D is a high performance diaphragm design, that is fully sealed and purpose-built for harsh conditions, like ice or environmentally contaminated environments.
Breathing underwater should feel natural, and that experience is one of the things that most clearly separate Halcyon second stages from our competitors. As soon as you experience the smooth, high volume of air delivered by a Halcyon second stage, you will be hooked.
Halcyon's H-75P offers many refined features that ensure consistent delivery, with performance, that ranks among the very best in our industry. The stable, intermediate pressure provides precise delivery of air to the second stage.
