Scuba diving offers endless opportunities to explore, but the adventure doesn’t stop after getting your Open Water certification. The right training can open doors to deeper wrecks, colder waters, and even technical dive training. Whether you’re looking to improve your skills, increase safety, or just try something new, PADI speciality courses offer an array of options.
Advanced Open Water: The Gateway to Specialties
The Advanced Open Water Diver course is where most divers start expanding their skills. It’s not a speciality course in itself, but it introduces you to different types of diving, including deep and navigation. Once completed, you’ll be certified to dive to 30 metres, which is essential for many advanced dives.
Many divers use this course to test out different types of diving before committing to a full speciality course. It includes five adventure dives, two of which are required: Deep Diving and Underwater Navigation. The remaining three can be chosen from a variety of options, including Peak Performance Buoyancy, Night Diving, and Wreck Diving.
While the Deep Diving adventure dive within the AOWD(Advanced Open Water Diver) introduces you to deeper dives (up to 30 metres), it’s important to note that the PADI Deep Diver speciality course allows you to go even further, down to 40 metres, and includes additional training on safety, gas management, and the effects of deeper dives. Many divers choose to continue their deep diving training with the PADI Deep Diver course to build on what they learned during their AOWD.
PADI Deep Diver: Exploring the Depths
If you’ve ever felt limited by the 30-metre depth restriction of the Advanced Open Water Diver course, the PADI Deep Diver course is the next logical step. This training takes you to 40 metres, where you’ll experience the effects of nitrogen narcosis, learn about gas management, and master deeper descents safely. It’s a more specialized course than the Deep Diving adventure dive within AOWD, as it focuses on the technical aspects of diving deeper and the increased risks involved.
The PADI Deep Diver course also teaches advanced techniques for descending and ascending safely, handling increased air consumption, and the potential risks of deeper diving. With PADI Deep Diver, you’ll gain a more in-depth understanding of deep dive procedures, which prepares you for even more exciting dive sites and further adventures.
Wreck Diver: History Beneath the Waves
Shipwrecks are some of the most thrilling dive sites. The Wreck Diver course teaches you how to penetrate wrecks safely, use a reel and avoid entanglements. Whether it’s WWII wrecks in Chuuk Lagoon(Micronesia) or sunken cargo ships in the Maldives, this course opens a whole new side of diving.
This course includes four dives, where you’ll learn to assess wreck stability, navigate inside and avoid silting out. Some divers combine this with sidemount diving to improve mobility in tight spaces. The wrecks you explore become like underwater time capsules, preserving history and marine life alike. For many divers, exploring a wreck is not only about the adventure but also about discovering a piece of history and understanding how these relics have shaped the underwater ecosystem.
Diving with Enriched Air (Nitrox)
Nitrox diving is one of the most popular PADI specialties for a reason. Using enriched air allows for longer bottom times by reducing nitrogen absorption. This is perfect for repetitive dives or deep wreck exploration. The course covers gas blending, maximum operating depths and how to use a Nitrox-compatible dive computer.
Since diving with enriched air reduces nitrogen loading, it’s often required for more advanced courses, such as PADI Tec 45 and PADI Tec 65. Nitrox diving is especially beneficial for divers who want to extend their time on deeper dives without increasing the risk of nitrogen narcosis or decompression sickness. It’s a perfect option for those who enjoy multiple dives a day, like on liveaboards, or are diving in areas with limited time at depth.
Drysuit Diving: Staying Warm in Cold Waters
Not all great dives happen in warm, tropical seas. The Drysuit Diving course is essential for those wanting to explore the cold waters of Scotland, Norway or even Antarctica. Unlike wetsuits, drysuits keep you insulated by preventing water from entering, making year-round diving much more comfortable.
A common misconception is that drysuits are only for extreme conditions. Many divers use them in temperate waters to extend dive times and improve comfort. Learning how to manage buoyancy in a drysuit is key to mastering this skill. The drysuit creates a completely different buoyancy challenge, as the suit itself becomes part of your buoyancy control. As a result, divers must learn how to adjust for this, ensuring safe and controlled ascents and descents.
Additionally, the course teaches divers how to choose the right undergarments and manage air in the suit to prevent discomfort and keep warm, ensuring you can stay comfortable even in colder waters.
PADI Ice Diver Course: Extreme Conditions
For those truly wanting a challenge, the PADI Ice Diver Course takes things to the next level. This involves diving under frozen lakes, using safety lines and learning emergency exit procedures. It’s an adrenaline-filled experience, requiring a solid understanding of gas management and exposure protection.
Ice diving also offers unique visibility and marine life encounters, making it an unforgettable experience. drysuit diving is a prerequisite, as temperatures can drop below freezing. Ice diving is an entirely different environment compared to typical recreational diving, demanding more focus on safety, emergency preparedness and the unique techniques involved in diving beneath ice. The course provides an unmatched thrill, with the added responsibility of managing potential emergencies in such a challenging environment.
Technical Diving Courses: Going Beyond Recreational Limits
If you’re looking for deeper, longer and more challenging dives, technical diving might be the next step. Technical dive training includes advanced gas planning, decompression procedures and different equipment configurations. Some of the most sought-after courses include:
- PADI Tec 45: The first step in tec diving, allowing for staged decompression dives.
- PADI Tec 65: Expands on Tec 45, introducing trimix diving and extending depth limits.
- Sidemount Course: Teaches you how to dive with tanks on your sides instead of your back, improving flexibility and gas management. Originally a cave diving technique where the ability to navigate narrow passageways without removing kit is an obvious advantage.
These courses require advanced training, but they open the door to decompression diving, deep wreck exploration and even cave diving. Technical diving introduces a much greater level of planning, as well as the need to be proficient with multiple gas mixtures, dive tables and advanced safety protocols. The skills you acquire in these courses prepare you for diving at extreme depths or through tight, confined spaces where technical proficiency and safety are paramount.
SSI Specialty Courses: Another Pathway
While PADI is the most well-known agency, SSI specialty courses offer similar training. Some divers prefer the flexibility and digital learning materials that SSI provides. Whether you choose PADI or SSI, the skills gained will improve your diving knowledge and safety.
SSI also offers technical diving programs that mirror PADI’s Tec courses, providing an alternative for divers seeking advanced training.
