Advanced Diver


The purpose of this course is to give the diver an overview of 5 different specialties, 2 core, and 3 additional SDI Specialties. The two core specialties are, SDI Deep and Navigation. One dive, from each of the specialties, may apply toward a complete specialty certification. Overhead environments and non-diving specialties are not allowed, and do not count toward the 3 chosen specialties. If computer Nitrox is to be used as one of the elected specialties, the instructor must be an SDI Computer Nitrox Instructor.
