The Advanced Open Water Diver course is all about advancing your skills. You'll practice navigation and buoyancy, try deep diving and make three specialty dives of your choosing (it's like a specialty sampler platter). For every specialty dive you complete, you can earn credit toward PADI® specialty certifications. Here are a few of the many options: Deep, Digital Underwater Photography, Dive Against Debris, Dry Suit, Enriched Air Nitrox, Fish Identification, Night, Peak Performance Buoyancy, Search & Recovery, Underwater Naturalist, Underwater Navigation, and Wreck Diver. Check out the Frequently Asked Questions section for a complete list of specialty dive options.
