Keys Huka Dive, Marathon

Master Scuba diving trainer Captain Jerry Williams knows a bit about navigating open water—he's a US Coast Guard captain. He taps into his nautical experience at Keys Huka and Scuba, where he leads classes ranging from basic open water scuba diving to dive master classes. During sessions, Captain Williams and his staff teach everything from the basics to specialties such as digital underwater photography that doesn't require an underwater darkroom. They also helm hookah dives, which are a combination of snorkeling and scuba diving, as well as snorkeling trips that explore wildlife and reefs.
