Advanced Ocean Diver sits between Ocean Diver and Sports Diver and is open to qualified BSAC Ocean Divers (or an equivalent other agency grade) who would like to progress their maximum diving depth to 30m. You will develop your existing Ocean Diver knowledge to support deeper diving. To enrol on the Advanced Ocean Diver, you must have successfully completed the BSAC Ocean Diver course. It is also open to those who have an equivalent certification from another recognised diver training agency and have completed Nitrox training. You must also be aged 14 or over to be able to progress to depths up to 30m. Current BSAC Sports Diver trainees who have completed the necessary skills and theory modules and are aged 14 or over can also apply for their Advanced Ocean Diver qualification to dive to 30m. he Advanced Ocean Diver course includes four theory sessions, which can be completed either via eLearning or in person with an instructor, giving flexibility for students and instructors. Practical sessions include two open water lessons and two depth progression dives. Centers can complete the AOD course in two days and make the most of BSAC’s digital and eLearning resources.
