Halcyon® was created in response to the demands of extreme
    technical diving. In the early 1990s, Halcyon® founders
    were exploring deep wrecks and long-distance caves,
    including the world-renowned Wakulla Springs.
    No other site can draw the comparison of being the Mt. Everest of cave diving:
    massive conduit (often over a 30 meters in diameter), deep, multi-branching
    passages, and passages explored to nearly 10km. Dives in Wakulla are the
    longest ever done: bottom times for the lead team can exceed ten hours at
    a depth of 90m. By the time the team exits the water, they will have spent
    nearly 30 hours underwater.
    Deep wrecks and long-distance cave diving are both physically and mentally
    demanding. Halcyon® CEO Jarrod Jablonski has invested nearly 20 years leading
    just this sort of extreme expedition in projects around the world. As Global
    Underwater Explorers (www.gue.com) President and the lead Woodville
    Karst Plain explorer, Jarrod Jablonski has more exploration dives in Wakulla
    than anyone alive.
    In fact, Halcyon® was founded in large part to be able to provide the gear he
    needed to make the dives as safely as possible. This history remains a vibrant
    part of the daily operations through the daily management of Halcyon® COO
    Casey McKinlay. Casey is the WKPP Project Director and oversees the planning
    for each exploration dive weekend. Casey also joins Jarrod and teams of explorers
    for expeditions across the globe. Over the course of these projects, dozens of
    divers spend hundreds of hours in a range of extreme underwater settings.
    Exploration divers who push the limits of underwater exploration demand
    that their Halcyon® equipment performs fl awlessly.
