This course and certification is the highest and most prestigious non-leadership rating that may be attained by a Scuba Educators diver. It is considered the supreme standard of diving excellence and recognition of expert training.

This course of instruction is often offered to students over a period of time rather than in a formal class environment. In this way, students can build knowledge and skills while meeting all the completion requirements including other specialty courses.

By taking Advanced OWD Level 2 and/or Level 3 courses and making at least 15 dives on the diver’s own, and 10 dives during the program, a total of at least 40 dives is logged.
