Lead dives and dive trips! Take certified divers on vacations to the world's best dive sites, how exciting!

The NAUI Divemaster course is an advanced training program designed for divers who want to take their passion for scuba diving to a professional level. As a NAUI Divemaster, you'll gain the knowledge and skills necessary to lead dives and dive trips, supervise certified divers during various diving activities, and assist in dive training. This certification is recognized as the highest NAUI leadership-level certification, second only to becoming a NAUI Instructor​​​​​​.

To qualify for the NAUI Divemaster course, divers must meet several prerequisites, including being at least 18 years old, holding certifications for NAUI Open Water Scuba Diver, Rescue Scuba Diver, Nitrox Diver, and Master Scuba Diver, or their equivalents. Additionally, candidates need to have logged a minimum of 50 open water dives totaling at least 25 hours of bottom time, demonstrate excellent water skills equivalent to a NAUI Assistant Instructor, and have current certification in First Aid for the Diving Professional. A medical examination with approval for diving by a licensed physician within the past 12 months is also required​​​​.

The course covers a wide range of topics and practical workshops, including dive leadership, supervising dive activities, diver safety and risk management, conducting dive briefings, organizing search and recovery projects, and mapping open water sites. The program aims to develop your ability to organize and direct various scuba diving activities, making you a role model for divers everywhere​​.

Upon successful completion of the course, NAUI Divemasters are qualified to organize and conduct enjoyable open water dives for certified divers, provided the diving activities and locales are similar to those in which they were trained. They are also qualified to assist NAUI Instructors in diving courses and may teach NAUI-DAN First Aid programs if they complete the necessary orientation. For those looking to advance further, the Divemaster certification is a stepping stone to entering a NAUI Instructor Training Course (ITC)​​​​.

This certification not only enhances your diving knowledge and skills but also opens up career opportunities in diving across the world, whether at dive resorts, charter tours, or local dive shops. It's an opportunity to share your love for diving by leading and mentoring others in this exciting underwater activity.
