Master
Scuba Diver
The NAUI Master Scuba Diver course is designed for experienced divers who want advanced training across a wide range of dive sites, conditions, and activities. Open to divers 15 years or older with Advanced and Rescue certifications, this course builds mastery, confidence, and leadership-ready skills.
About the Course
Considered the ‘Black Belt’ of recreational Scuba diving, the NAUI Master Scuba Diver course is the highest recreational certification level one can achieve as a non-professional diver. We’ll get deeper into the physics and physiology of diving as well as equipment, environment and advanced techniques. This is not just a ‘tick the boxes and get your card’ course. Like every NAUI course, you EARN your certification.
During training, students will engage in a minimum of eight open-water dives, including the following required dives:
Emergency procedures and rescue
Deep/simulated decompression diving
Limited visibility or night diving
Advanced underwater navigation
Search and recovery – light salvage
