Halcyon RB80 Rebreather
World Record Not Included

Divers from the icy waters of the Antarctic to the caves of the Woodville Karst Plain rely on the Halcyon Rebreather operating system’s unique capacity for reliable, safe and intuitive rebreather diving. No other rebreather in the world is used as consistently and effectively as the Halcyon for deep wreck and deep, long cave exploration. Halcyon Rebreather runtimes are often in excess of six hours from the surface at depths of 300 feet.

Halcyon’s extremely intuitive and very reliable operating system eliminates the distractions that can mean the difference between a successful or failed mission. The simplicity that gives the Halcyon its advantage for exploration is just as important for less demanding environments-- don’t you want the same margin of safety on your dive as the explorer hundreds of feet deep on Trimix, miles from the daylight?

New Stainless Tank Rack

If Halcyon’s reputation rested on its safe operation, we can now add size, weight, and maneuverability to the list. Halcyon’s relentless pursuit of innovation has paid off with the Halcyon RB 80, incorporating all the unique and proven concepts of the Halcyon Rebreather in a package smaller than an aluminum 80 dive cylinder.
Starting with patented Halcyon technology, designer Reinhard Buchaly facilitated Halcyon's next revolution in rebreather technology. Working together on this revolutionary design the team expanded upon proven Halcyon technology in the creation of a novel unit sized at less than 1/3 of the original Halcyon while actually expanding scrubber size and adding a patent pending automatic water removal system.
