NAUI Technical Courses
Is technical diving for you? NAUI Technical Courses are designed for divers whose
interests include diving beyond traditional recreational limits and specific areas
of technical diving. Accordingly, technical diving courses are designed to provide
more detailed training than specialty diver courses and result in more extensive
qualifications.
|
|
NAUI was the first training agency to certify all levels of diving ranging from
traditional recreational training through all levels of technical training. Technical
diving is a potentially dangerous activity that requires special training,
equipment, and qualified support teams. NAUI Technical Instructors are qualified to not only certify
you for your dive objective, but also to provide a healthy respect for the technical
diving environment.
