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 trainin through all levels of technical training. Technical
diving is a potentially dangerous activity that requires very special training,
equipment and support. NAUI Technical Instructors are trained to not only qualify
you for your dive objective, but also to give you a healthy respect for the technical
diving environment.
|
|
Below are just some of the NAUI Technical Courses available through your local NAUI
Technical Training Dive Center. Be sure to ask your NAUI Technical Instructor about
previous training or experience you may need and get ready to enter the unique world
of Technical Diving!
