Ray Hollister
Commercial and recreational dive operations veteran with over four decades of experience in Florida waters, specializing in gear performance assessment under real-world tropical and subtropical conditions.
Ray has been diving the Atlantic coast and Gulf waters since the late 1970s, accumulating more than 8,000 logged dives across every imaginable condition from clear reef dives to murky wreck penetrations. He's spent the better part of his adult life helping recreational divers select, maintain, and trust their life-support equipment. After decades of hands-on experience with nearly every piece of gear that's come to market, he's developed strong opinions about what works, what doesn't, and why most marketing claims don't survive contact with saltwater.
