The Advanced Open Water Diver course is all about expanding your skills. You'll complete two required dives—deep diving and underwater navigation—then choose three additional specialty dives based on the local environment and what excites you most, for a total of five dives. Each specialty dive you complete can earn you 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.
