One of our most popular regulators, DDS has chosen this with H-75P First stage, Aura second and Halcyon Master Diver SPG as our standard rental regulator!

Purchase a complete Halcyon regulator first stage, second stage, alternate air source, SPG and DIR hose kit and we’ll throw in a free regulator bag, stainess steel bolt snaps for primary and spg hoses and necklace.

First introduced in 1986 as the G250, it was the first regulator to introduce an adjustable Venturi Initiated Vacuum Assist (VIVA). Today’s modern version features metal components (inlet tube, orifice, inhalation control knob and hose connector) for excellent cold-water performance. It also offers a left-right hose attachment option, making it a great choice for tech diving configurations.

Of course, you don’t need to dive in cold water or find yourself in extreme diving conditions to fully appreciate the powerful yet easy-breathing attributes of this reg system. But if you’re a demanding diver you can rest assured that with every breath you take, the Halo will deliver effortless airflow and consistent top-of-the-line performance.
