The instructors at Deep Blue Scuba teach aquatic proficiency through the rigorous and comprehensive ANDI certification system. ANDI certification imparts pupils with the skills necessary to dive self-sufficiently or with companions, and trains students via pool sessions and open-water dives set in the crystalline near Port Aransas. After mastering descent and ascent techniques, students can expand their knowledge base through a slew of specialty courses including underwater navigation, night diving, and wreck diving. Scuba instructors map out the best local dive locations and host periodic Discover Scuba outings where divers sample new gear and reacquaint themselves with watery skills. The diving enterprise also hosts expeditions to far-away waters, piloting trips that explore Australia and Mexico, and confront the notorious gangs of clownfish that lay claim to the Florida Keys.
