Enriched Air Diver (Nitrox) – This is PADI’s most popular specialty scuba diving course, and it’s easy to see why.
Scuba diving with enriched air nitrox gives you more no decompression dive time. This means more time underwater, especially on repetitive scuba dives. You can typically stay down longer and get back into the water sooner. No wonder many divers choose this as their very first specialty. 

Dive Computer – A dive computer tracks your dive depth and time. It calculates theoretical nitrogen using a decompression model and displays the time and depth limits you need to stay within. Learn about the basic styles of dive computers and required and optional features you should be looking for. 

Digital Underwater Photography – It’s hard to imagine activities more versatile than underwater imaging: underwater photography. Whether snorkeling, exploring amid reefs, under ice, at altitude, or on wrecks, if there’s something worth seeing, there’s something worth photographing. This makes underwater photography a pursuit that mixes well with your other diving activities, and one that permits you to share the underwater world with non-divers. Learn the basics of underwater digital or sign up for the advanced class to sharpen your skill in flash, backlighting and macro. 

Wreck Diver – Whether sunk on purpose as an artificial reef or the result of mishap, wrecks open fascinating windows to the past. Most divers find wrecked ships, airplanes and even automobiles nearly irresistible because they’re intriguing to explore, exciting avenues of discovery, and usually teeming with aquatic life. The PADI Wreck Diver course teaches you the ins and outs of rewarding, responsible wreck diving.

Boat Diver – Whether you’ve never made a boat dive or you’ve logged dozens, the PADI Boat Diver Specialty course can benefit almost every diver because different boats in different parts of the world do things differently. 

Peak Performance Buoyancy – Scuba divers like to be neutrally buoyant so they neither sink nor float. It can be a tricky skill to learn. Divers who have mastered the highest performance levels in buoyancy stand apart. You’ve seen them underwater. They glide effortlessly, use less air and ascend, descend or hover, almost as if by thought. They interact gently with aquatic life and affect their surroundings minimally. The PADI Peak Performance Buoyancy course refines the basic skills you learned as a PADI Open Water Diver and elevates them to the next level.

Night Diver – Introduce yourself to the whole new cast of critters that comes out after the sun goes down. See your favorite dive sites from a whole new perspective at night. You will learn night diving planning, organization procedures techniques and potential problems. Learn to control your buoyancy, handle entries, exits and underwater navigation at night.

Search and Recovery – Have you ever dropped something in the water? Are you looking for lost “treasure”? The PADI Search and Recovery Diver Specialty course will teach you effective ways to find objects underwater and bring them to the surface. Small, large or just awkward, there is a way to bring them up.

Dry Suit Diving – Depending on where you are, a dry suit may mean the difference between diving or missing the fun, between a long comfortable dive and a short shivering one, or between diving year round versus only a few months in the warm seasons. You will learn special techniques you don’t need with other exposure suits. The first time you dive with a dry suit, diving without getting wet is pretty cool. Well, warm. You know what we mean.

Altitude Diving – This course will cover how to determine that a dive is an “altitude dive”. You will need to follow special dive table and computer procedures at altitude. You will learn the theoretical and practical differences between altitude diving, flying after diving and driving to altitude after diving.
