Make a difference on every dive by activating your inner citizen scientist. During the Dive Against Debris® Diver Specialty course, you’ll learn how ocean plastic and trash cleanups not only keep your local dive sites healthier, but also how to contribute to a global database that documents our planet’s marine debris problem. Under the guidance of your instructor, you’ll participate in a Dive Against Debris survey and turn your passion for the underwater world into real action.

Enriched air, also known as nitrox or EANx, contains less nitrogen than regular air. Breathing less nitrogen means you can enjoy longer dives and shorter surface intervals. No wonder Enriched Air Diver is the most popular PADI® specialty.

If you’re new to boat diving or want to learn more about diving from different types of boats, enroll in the PADI® Boat Diver course. 

During two dives with an instructor you’ll learn nautical terminology, boat diving etiquette and may practice using lines and/or deploy a surface marker buoy (SMB).

If scuba diving is like taking a scenic stroll around a park, a Diver Propulsion Vehicle (DPV) is like exploring a neighborhood on an (electric) bicycle. 

DPVs, also called underwater scooters, allow you to see more, conserve air and get from one place to another faster - with a huge smile on your face.

Love sharks? Scared of sharks? Or do you just want to know more about them? Enroll in an AWARE Shark Conservation Specialty course and discover the value of sharks to marine ecosystems and economies. You'll learn more about the causes of declining shark populations and the actions you can take to become a knowledgeable and passionate shark defender. By being informed, you can dispel misconceptions and act to protect sharks. Sharks need you!

If you're a PADI (Junior) Open Water Diver who is at least 12 years old, you can enroll in the AWARE Shark Conservation Diver Specialty course.

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.

PADI (Junior) Open Water Divers or higher, who are at least 10 years old, are eligible to take the Peak Performance Buoyancy course.

Discover the balance and efficiency of sidemount scuba diving with your PADI dive instructor. Many divers find sidemount tanks are more comfortable and easier to put on in the water. Sidemount diving is also beneficial for divers who want improved balance and prolonged dives.

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.

If you're at least 10 years old and certified as a PADI (Junior) Scuba Diver or higher, you can enroll in the Equipment Specialist course.

Learn the skills specific to diving in a quarry.

Boats and currents are two common factors associated with many dive sites. Boaters don't always recognize that divers are in the area and current can carry you further than expected. Launching a delayed surface marker buoy (DSMB) before you surface can alert others to your location in advance of your ascent. Adding another layer of safety, you can also use the DSMB line to complete your safety stop, which is advantageous in a current or when there are no other visual references. Take this course to learn about all the beneficial uses of a DSMB.

You need to be a PADI Open Water Diver who is at least 12 years old to enroll in the DSMB Diver course.

Diving in a current can feel like flying underwater. In the PADI® Drift Diver course, you’ll learn drift diving tips from an experienced instructor and practice buoyancy control, navigation, use of surface signaling equipment and buddy communication.

“What was that fish?” is a common question heard after a dive. If you want to be the scuba diver with the answers, instead of the one asking the questions, then take the Fish Identification Specialty course. You'll enjoy your dives even more when you recognize the creatures that you see and can identify the main fish families and their characteristics.

If you're at least 10 years old and a PADI (Junior) Open Water Diver or higher, you can enroll in the PADI - Fish Identification course.

The thought of dipping below the surface at night seems mysterious, yet so alluring. Although you've been scuba diving at a site many times before, at night you drop into a whole new world and watch it come to life under the glow of your dive light. The scene changes as day creatures retire and nocturnal organisms emerge. If you've wondered what happens underwater after the sun goes down, sign up for the PADI Night Diver Specialty course.

PADI (Junior) Open Water Divers or higher, who are at least 12 years old, can enroll in the Night Diver specialty course.

Rebreathers used to be only for technical diving, but not any more. New Type R (recreational) rebreathers are lightweight, easy-to-transport and have sophisticated electronics to simplify their use. Why dive a rebreather? You get longer no stop limits, reduced gas consumption because you reuse most of your exhaled gas, and unmatched wildlife encounters because you don't release annoying bubbles. The PADI Rebreather Diver course introduces you to rebreather diving to a maximum depth of 18 metres/60 feet and lets you experience things you never imagined possible as a scuba diver.

​

To enroll in the PADI Rebreather Diver course, you must:

• Be a PADI Open Water Diver

• Be a PADI Enriched Air Diver

• Have a minimum of 25 logged dives

• Be at least 18 years old

Dive Theory will dramatically expand your understanding of dive physics, physiology, equipment, decompression theory and dive planning.

Any diver can complete Dive Theory eLearning for personal enrichment. PADI Divemaster, IDC, IDC Staff and CDTC candidates may earn credit toward the dive theory exams. Ask your instructor for details.

Imagine descending below the surface of a clear mountain lake to explore a well-preserved wreck. Interested? Any time you scuba dive at an altitude higher than 300 metres/1000 feet above sea level, you're altitude diving. If you're ready to discover a hidden world where few have ventured, then the PADI Altitude Diver Specialty course is for you.

PADI (Junior) Open Water Divers who are at least 10 years old are eligible to take the Altitude Diver course.

During the PADI® Digital Underwater Photographer course, you’ll learn how to take underwater photos you’ll be proud to share with others. 

Avoid beginner mistakes and shorten the learning curve with tips from the pros. Learn how to use underwater photography lights (strobes), avoid backscatter and enhance color.

Unlike wetsuits, drysuits are filled with air. During your drysuit course, your instructor will teach you how to control the air in your drysuit along with your buoyancy.

You'll also learn about different types of drysuits, basic drysuit repairs and maintenance.

Working divers, such as public safety divers, use full face masks because they protect the eyes and nose from contaminants in the water, provide comfort in cold water, and allow for communication. If you're interested public safety diving, scientific diving, or venturing into extremely cold-water, then learning to dive with a full face mask is definitely for you. Because full face masks allow you to breathe from your nose, they are also beneficial for those who have difficulty using standard scuba masks. Diving with a full face mask offers a different experience and that alone may be reason to give it a try.

You need to be a PADI Open Water Diver who is at least 12 years old to enroll in the Full Face Mask Diver course.
