Advanced Diving Program Helps Divers Build Skills, Confidence, and Underwater Experience
Divers looking to expand their abilities and explore greater depths can take part in an advanced training program designed to strengthen knowledge, confidence, and practical skills. Some dive operators require proof of advanced certification before allowing deeper dives, making this course an important step for those ready to progress beyond beginner-level experiences.
The program includes three guided boat trips and a series of supervised dives focused on essential techniques such as navigation, deep diving, and night diving. Participants can also choose from a range of specialty activities, including fish identification, search and recovery, peak performance buoyancy, underwater photography, and hunting. The course package includes learning materials, equipment rentals, boat trips, and registration, while students receive the course book in advance to study at their own pace without a formal exam requirement.
Open to divers aged ten and above, the program provides six additional supervised dives that allow participants to practice new techniques in real-world conditions. With guidance from experienced instructors, students develop better control, awareness, and decision-making skills while gaining the confidence needed for more challenging underwater adventures.
The training approach focuses on creating safe, knowledgeable, and capable divers rather than promoting a single certification system. Courses are available through major organizations including NAUI, PADI, and SSI, with each providing recognized learning methods. Whether through traditional study materials, digital learning platforms, or structured knowledge reviews, the program ensures that every participant develops a strong foundation in diving principles and is prepared for advanced underwater exploration.

Customer Reviews

I had an absolutely fantastic weekend doing my orientation dive (and fun dives) with Ocean Divers at Killary Fjord! From the moment I arrived every member of staff and all the other divers were incredibly welcoming, friendly and helpful. The atmosphere was supportive and relaxed, making it easy to feel comfortable even if you’re just starting out like me (10 dives previously). There were a lot of divers, but each in small groups with their own dive master or dive instructor and grouped together in the OW/AOW courses or fun dives. While I had already done my OW elsewhere, I’ll definitely be doing the advanced course and further dives with these guys as the level of dedication and commitment that goes into making their students be successful divers is visible. Bring a bit of patience for the initial response period if you reach out during a very busy time - it‘s hard to respond when you’re always in the water 😄 but I honestly can’t recommend them enough if you’re looking to become a good diver and explore Irelands underwater world with a genuinely lovely group of people.

I’m doing the drysuit diver course with Oceandivers at the moment. I was having trouble getting my buoyancy right, so had six pool sessions to get it right at no extra charge!! What a crew Oceandivers have. There was no pressure, just take your time and get it right. Dan is always on hand to help you out and the rest of the lads are so helpful. I had my first sea dive for the buoyancy certification today off Dalkey island. It was fantastic!! The extra lessons really paid off. I cannot recommend the Oceandivers crew highly enough. It is and has been a pleasure working with Oceandivers to get my drysuit certification. Can’t wait to get back in the water with the crew!!

I got my OW course with Oceandivers in the previous two months and they are really professional and helpful. Especially, I would like to thank my instructor Alan, he is really amazing experience diver and nice advisor. Great enjoy my training with him and also thank other instructors, divemasters and staffs from Oceandivers.
