Master Scuba Diver

The course is a continuing education certification course for divers who wish to increase their understanding and enjoyment of diving. Emphasis is on student participation and practical application of knowledge in open water after a classroom discussion of subjects. This course is an excellent progression toward NAUI Leadership roles. Some subject areas are a review and expansion of material from previous courses. Each subject area is a progression in study not a definitive study in the particular diving activity. However, instructors will specify performance objectives for related course diving activities; for example, during a navigation dive the student will swim a reciprocal course to within 3m (10 ft.) of its origin.

The course may be divided and taught in sections with the student’s Diving/Training Log being signed off for each activity until all requirements are met. Upon successful completion of this course, graduates are considered competent to engage in open water diving activities without supervision, provided the diving activities and the areas dived approximate those of training.
