While all the specialties expand your knowledge and skills, Peak Performance Buoyancy, Enriched Air (Nitrox) Diver, Underwater Navigator, and Equipment Specialist Specialties are arguably some of the most important specialties for increasing your skills and improving your diving.

Peak Performance Buoyancy

Excellent buoyancy control is what defines skilled scuba divers. You’ve seen them underwater. They glide effortlessly, use less air and ascend, descend or hover almost as if by thought. They more easily observe aquatic life without disturbing their surroundings. You can achieve this, too. The PADI Peak Performance Buoyancy Specialty course improves the buoyancy skills you learned as a new diver and elevates them to the next level.

Enriched Air (Nitrox) Diver

The PADI Enriched Air Diver course is PADI’s most popular specialty scuba course. Why? Because scuba diving with enriched air nitrox gives you more no decompression time, especially on repetitive scuba dives. If staying down longer and getting back in the water sooner sounds appealing, then don’t hesitate to become an enriched air diver.

Underwater Navigator

Be the scuba diver everyone wants to follow because you know where you are and where you’re going. The PADI Underwater Navigator course fine-tunes your observation skills and teaches you to more accurately use your compass underwater. If you like challenges with big rewards, take this course and have fun finding your way.

Equipment Specialist

Don’t miss a dive due to minor issues with your scuba diving equipment. Whether it's a missing o-ring, wetsuit tear or a broken fin strap, the PADI Equipment Specialist course teaches you to manage basic repairs and adjustments. You'll also learn more about how your gear works, making you more comfortable with it and better prepared to take care of your investment.
