While most people know how to breathe, very few can do so underwater without the proper equipment and training. In Too Deep Scuba?s open-water PADI certification courses provide just that, pairing classroom instruction with confined-water practice dives in which participants don full scuba gear. Students can plunge deeper into the world of aquatic exploration by pursuing other certifications, earning a new status as a rescue diver, master scuba diver, or ship?s mermaid figurehead. In Too Deep Scuba?s team also schedules trips where divers can hone their skills in exotic waters, such as Florida?s Crystal River and Bonne Terre Mine. Before excursions, divers can stock up on an array of gear from Pinnacle Aquatics, Cressi-sub, Ocean Reef, and other outfitters.
