Popular PADI Specialties
Enriched air diver
The PADI Enriched Air Diver is PADI's most popular specialty, and there's a good reason why! Enriched Air Nitrox increases no-stop times, lowers your residual nitrogen and is even claimed to leave you less tired after a day of diving. Whether it's a cruise ship port or a weeklong liveaboard, you'll get requests for Nitrox use and Nitrox courses, making this specialty one of the most useful specialty courses you can teach.
Peak Performance buoyancy Diver
Perfecting your buoyancy is one of the best things you can do for your diving. With better buoyancy comes less air consumption, less energy consumption and less damage to the reef! Your Open Water Scuba Instructor will come with the Peak Performance Buoyancy specialty instructor rating, but this is a supremely useful course to be able to teach, and one that you should encourage all your divers to pursue.
As a PADI Advanced Open Water Diver, you are certified to go to maximum 30m/100ft. For those daredevils that want to learn how to go deeper, the PADI Deep Diver specialty is a very good specialty to teach people about diving deeper in a safe and thoughtful manner.
PADI offers a variety of other useful specialty ratings, including Underwater Naturalist Diver, Night Diver, Wreck Diver, Search & Recovery Diver, Underwater Navigation Diver and Digital Underwater Photography Diver.
