Just because it’s winter, doesn’t mean you have to put away your flippers. Pack up a dry suit — and some hot cocoa — and give ice diving a try. This specialized type of scuba diving requires additional training because it takes place under ice and typically has a single entry/exit point, making it much more dangerous than regular diving.
Ice divers must learn how to recognize unsafe ice conditions and how to prepare a dive site because it requires cutting a hole in the ice. Divers must also wear a harness and learn to communicate via a series of tugs because ice divers must be tethered to a safety diver on the surface.
