Scuba Shack instructors introduce novices to scuba skills during the PADI Open Water Diver Course, one of the world's most popular scuba courses. Limited to a small class size of up to six people, students learn about proper equipment and what's necessary to be a safe and confident diver—including the memorable moment of breathing underwater for the first time. A certification may be earned in as little as two weekends. Scuba Shack also offers dive travel to several destinations, such as the Florida Keys, the Bahamas, the Cayman Islands and more.
