Skin Diving Instructor

Skin Diving Instructor (SDI)

Want to begin working as a professional in the field, organizing your own courses, issuing certifications and conducting open water skin dives? NAUI Skin Diving Instructor training will enable you to join NAUI as a leadership member and independently conduct skin diving training. Because of the growing popularity of snorkeling and skin diving, this may gain you substantial financial rewards. You can also team-teach with a NAUI Instructor, offering the skin diving portion of the Scuba Diver Course.

The course will make available to individuals, schools, camps, or similar groups NAUI Leaders who can effectively teach people to enjoy skin diving with minimal risk.
