High quality and functionality meets professional and efficient design. This regulator set from Halcyon consists of the H50D fist stage (DIN), the Aura second stage, an Aura Octopus and a free Termo Gauge.
If you frequently dive in extreme cold or harsh conditions in general, the H50D first stage is a great choice for you. It has a high-performance diaphragm design, which is fully environmentally sealed. The two opposing high-pressure ports allows for a flexible montage of you regs depending on your personal preference. The Halcyon H50D makes breathing smooth and easy under any dive condition.
The Aura second stage is a classic, reliable downstream valve in a simple and compact design. Inhalation efforts are kept at a minimum with the Halcyon Aura. It also features an Air Control Vane (ACV) to fine tune your breathing underwater or keep the reg from free-flowing while not in use. You will definitely enjoy the super comfortable mouthpiece that reduces jaw fatigue and irritation.
