The highest non-leadership recreational scuba diver certification issued by some agencies
Not to be confused with Master Diver (United States Navy).
Master Scuba Diver (MSD) is a scuba divingcertification or recognition level offered by several North American diver training agencies, such as the National Association of Underwater Instructors (NAUI), the Professional Association of Diving Instructors (PADI), Scuba Diving International (SDI), and Scuba Schools International (SSI). Other agencies (e.g., The International Association of Nitrox and Technical Divers) offer similar programs under other names, such as "Elite Diver". Each of these (and other) agencies touts their program at this level as the highest, non-leadership program.
Most organizations have a minimum age requirement of 15 to undertake the Master Scuba Diver course, although some organizations do permit certification of "Junior" Master Scuba Divers.
Different agencies take different approaches to this program creating both a disparate level of indicated diver competence both within most agencies as well as from agency to agency. The specific methodologies of the main agencies are as follows:

IANTD awards their Elite Diver Recognition[1] to a diver who completes:
IANTD Advanced Open Water Diver.

NAUI[]
The NAUI Master Scuba Diver course[2] is one of such courses offered by the major North American diver training organizations that is designed with both a skill based and academic core. The NAUI Master Scuba Diver course was specifically designed by two NAUI Instructors: Paul Heinmiller (NAUI 5141L) and Phil Sharkey (NAUI 4505L),[3] to meet a specific need that had been identified by the NAUI membership: a clearly defined course that provides, tests for, and certifies to, all the academic and skill training required of a NAUI Instructor, excepting topics covering teaching theory and methods and supervision of students and certified divers, topics that are part of NAUI's Divemaster and/or Instructor Training Course.
