Advanced Open Water Diver

The ISDA Advanced Open Water Diver course represents the completion of the diver’s basic preparation and a first step towards deepening one’s personal interests.

With this course you acquire the skills and knowledge of an expert diver by improving your experience in 5 different specialties under the guidance of your ISDA Instructor.

The Course

Compass orientation and Deep Dive are mandatory specialties for this course, which allow to dive in autonomy up to 39 meters. The other specialties can be chosen from the student and agreed with the Instructor, like the course AOWD.
