The PADI Advanced Open Water course is all about advancing your skills. You'll practice navigation and buoyancy, try deep diving and make three adventure dives. This commonly covers Peak Buoyancy, Night and Underwater Naturalist or Search and Recovery, but your instructor is open to any specialty you may be interested in. For every adventure dive you complete, you can earn credit toward PADI specialty certifications. Here are a few of the many options offered: Deep, Digital Underwater Photography, Dive Against Debris, Dry Suit, Enriched Air Nitrox, Fish Identification, Night, Peak Performance Buoyancy, Search and Recovery, Underwater Naturalist, Underwater Navigation, and Wreck Diver.
