First-time scuba divers will learn from professional, certified trainers during Skin-n-Scuba?s Discover Scuba training session. The training course includes all necessary diving gear and is conducted in the facility?s 26?x52? indoor saltwater pool, featuring salt, water, and two sunken Spanish Armada galleons. Individual class enrollment is capped at 15 in order to maintain a reasonable instructor-to-student ratio and leave room in the pool for the dolphins enrolled in backstroke. The two-hour classes for Groupon buyers are offered Fridays (starting at 10 a.m., 1 p.m., and 3 p.m.), Saturdays (9 a.m. and 11 a.m.), Sundays (1 p.m. and 3 p.m.) and Mondays (10 a.m., 1 p.m., 3 p.m., and 5 p.m.).
