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.
