If you’re interested in rebreathers for their silence and maximized no stop dive time, and are happy to stay within recreational diving depth limits, then the PADI Advanced Rebreather Diver course is for you.

This course builds on your PADI Rebreather Diver certification by expanding your knowledge, adding a bailout cylinder, and training you to dive as deep as 40 metres/130 feet.

If you aren’t a certified rebreather diver yet, no problem – ask your PADI Rebreather Instructor about combining the PADI Rebreather and Advanced Rebreather Diver courses.

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

• Be a PADI Open Water Diver, but you must earn a PADI Advanced Open Water Diver certification to become a PADI Advanced Rebreather Diver
• Have a minimum of 30 logged dives
• Are at least 18 years old

To dive deeper than 30 metres/100 feet, you must be a PADI Deep Diver.

Note that qualifying certifications from other diver training organizations may apply – ask your PADI Rebreather Instructor.

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.

Learning to adjust your dive plan for the reduced surface pressure at altitude is an important part of the course. You’ll complete two scuba dives and learn:

• Altitude dive planning, organization, procedures and techniques.
• How to adjust your dive computer for altitude diving or calculate altitude dive profiles using the RDP Table or eRDPML^TM.
• How to avoid problems and handle emergency situations, if they occur, at altitude.

“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 AWARE – 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 AWARE – Fish Identification course.

Once you learn to recognize what types of fish you see, you’ll find it easier to reference the exact species after a scuba dive. For example, a butterfly fish in the Caribbean has a similar shape to a butterfly fish in Southeast Asia, but colors and markings may be wildly different. If you know what fish family it belongs to, you can more easily look up the local name or at least be able to intelligently ask the local scuba instructor what you saw.
During two scuba dives, you’ll learn:

• How to identify characteristics of local fish families and species.
• Fish survey techniques and strategies.
• About Project AWARE activities that can help protect aquatic life

Much of the world’s best scuba diving is accessible only by boat. Whether you’ve never made a boat dive or you’ve logged dozens, the PADI Boat Diver Specialty course will benefit you because boats in various parts of the world do things differently. Scuba diving from a boat is fun and relatively easy because you usually descend directly onto your dive site.

If you’re a PADI (Junior) Open Water Diver who is at least 10 years old, you can enroll in the Boat Diver course.

The PADI Boat Diver course will expand your knowledge about boats from small inflatables to large liveaboards. You’ll gain experience scuba diving by completing two dives from a boat in your local area and learn:

• Boat terminology.
• Boat diving procedures and etiquette, including how to enter and exit, and where to stow your gear.

Caverns exist in many areas where scuba divers venture – from freshwater springs to volcanic island walls and limestone coasts. In these locations you’ll find large, dark spaces that seem incredibly inviting, yet are potentially dangerous. The PADI Cavern Diver Specialty course gives you the knowledge and skills to explore caverns correctly – allowing you to enter far enough for adventure, but staying within the light zone for an easy exit to open water.

You need to be PADI Advanced Open Water Diver who is at least 18 years old to enroll in the Cavern Diver course.

Ready for a challenge? You’ll complete four scuba dives with the first focused on line handling, reel use and emergency procedures outside a cavern; and the next three dives put your new skills to use inside a cavern. You’ll also learn about:

• Other specialized equipment for cavern diving, such as lights and redundant breathing systems.
• Avoiding disorientation and anti-silting techniques.
• Dive planning, including depth and distance limits and air management for cavern diving.

The lure of the deep. There’s something exciting and mysterious about exploring deeper dive sites while scuba diving. Sometimes it’s a wreck that attracts you below 18 metres/60 feet, and on wall dives it may be a giant fan or sponge. Whatever it is, to scuba dive with confidence at depths down to 40 metres/130 feet, you should take the PADI Deep Diver Specialty course.

If you’ve earned the PADI Adventure Diver rating or higher, and you’re at least 15 years old, you can enroll in the Deep Diver course.

Your training starts by reviewing reasons for deep diving and how important it is to know your personal limits. During four deep dives with your instructor, you’ll go over:

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.

If you’re a PADI (Junior) Open Water Diver who is at least 12 years old, you can enroll in the Enriched Air Diver Specialty course. Note that in some regions the minimum age is older than 12.

You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session, and two optional (or required) scuba dives, you’ll:

• Discuss managing oxygen exposure.
• Practice analyzing oxygen content in your scuba tank.
• Set your dive computer for diving with enriched air nitrox.

You may be able to get college credit for the PADI Enriched Air Diver course – ask your instructor to learn more.

Knowing how and when to use emergency oxygen is a great skill to have and means you’re ready to help others should the need arise. Becoming a PADI Emergency Oxygen Provider lets you breathe easy knowing that you can recognize scuba diving illnesses treatable with emergency oxygen, and are prepared to offer aid.

There are no prerequisites, age restrictions or water sessions required for this course – it’s open to everyone. Scuba divers, snorkelers and anyone who is around divers – boat crew, lifeguards, etc. – will benefit from having this training.

You’ll learn about dive injuries, different types of emergency oxygen equipment and safety considerations when using oxygen. Then you’ll practice:

• Assembling and disassembling emergency oxygen equipment.
• Deploying a non-rebreather mask and a demand inhalator valve on a breathing diver.

Your instructor will show you how to overcome some common equipment problems and offer equipment configuration suggestions. You may even get to jump into the water to try new or unfamiliar equipment.

If extreme, unusual and challenging scuba diving scenarios appeal to you, try diving under the ice. Ice diving is one of the most adventurous scuba specialties because you confront conditions and see beauty few others ever experience. Plus, you might get a chance to play with your exhaled bubbles on the bottom of the ice. Flash your PADI Ice Diver certification card to get instant respect, and usually a lot of questions from other divers about what it’s like under the ice.

You need to be a PADI Advanced Open Water Diver who is at least 18 years old to enroll in the Ice Diver course.

Teamwork is essential for ice diving, so you’ll start by learning the roles and responsibilities of support personnel, tenders and safety divers.
