Breathing is one of the most important things you do while underwater. You should not accept “good enough,” when making such an important choice. That is why we have chosen high performance components, while designing regulators, for the ultimate diving experience. Halcyon regulators are used on the longest scuba dives ever accomplished, and in some of the harshest conditions; such as the deep wrecks of the Baltic Sea, and in the high altitude caves of the Russian interior.




Extreme cold water diving conditions pose a unique challenge to divers and equipment alike. Extreme temperatures can cause regulator “freezing,” during which a regulator might experience a free-flow. While this is not an imminent threat (because air continues to flow from the second stage), Halcyon systems greatly limit the risk of this occurrence. All Halcyon regulator systems are CE approved for 4300psi cold water diving. In fact, we even exceed the CE cold water requirements. To further reduce regulator freezing, Halcyon’s H-50D uses a dry ambient pressure chamber. Meanwhile, Halcyon second stages feature precision molded carbon fiber and technopolymer valve housing, and components which also contribute to their lightweight features and corrosion resistance.




The dive is the thing. We make the gear that we know will make diving better. It is knowing as opposed to guessing.

Halcyon Product Development

Much of Halcyon's reputation was earned through the hard work of underwater cave exploration in Florida, Europe, and Mexico. In the company's early days, Halcyon product development meetings were likely to be held in a Tallahassee sushi bar, after a hard weekend of cave exploration. Everyone would debate about how the current wing made a dive more or less comfortable, or how changing a material would be an improvement. While some of us were putting the gear through its paces in the caves, others were doing the same on wrecks and reefs, from the Baltic, to the Caribbean. As soon as the feedback filtered in, a new batch of wings, with the suggested changes in place, would roll out of the factory, made better by the previous two weekends of diving.
