Master Scuba Diver
The most respected non-professional certification in recreational diving.
The NAUI Master Scuba Diver rating carries a specific kind of respect in the diving community, because unlike an entry-level card, it can't be earned quickly. It requires a minimum of eight open-water dives across a demanding mix of required and elective skills, and it is widely recognized as the most credible non-professional certification a recreational diver can hold.
Required dives cover emergency procedures and rescue, deep or simulated decompression diving, limited-visibility or night diving, and underwater navigation combined with search, recovery, and light salvage work. These are deliberately the dives that expose gaps in a diver's competence, so completing them properly, not just quickly, is the point.
Elective dives let you round out your logbook around your own interests: skin diving, environmental study and survey techniques, practical air-consumption management, and boat diving among the common choices. By graduation, most divers have a noticeably broader and more resilient skill set than when they started.
Master Scuba Diver is also a genuine gateway credential. Completing it is a prerequisite for the NAUI FIT program, which in turn opens the door to professional membership as a NAUI Leader or Instructor, for divers who want to start teaching rather than only diving.
Master Scuba Diver is also the springboard into professional diving: it satisfies the experience prerequisites for the NAUI FIT preparation program and stands among the required certifications for Assistant Instructor and Divemaster candidates.
