NAUI Technical Diver Courses
NAUI Technical Diver Courses address particularized areas
of technical diving. Accordingly, technical courses are designed
to provide more detailed training than specialty diver courses
and result in more extensive qualifications. In these instances,
the qualifications are described in the respective technical
course standard. They provide divers the opportunity to enjoy
organized diving, which yields experience and documents training
in technical diving activities. Instructors with expertise in
specific areas of technical diving may design their own technical
training courses also.
Note: Members
and affiliates operating within areas under the United States
of America’s Occupational Health and Safety Administration
(OSHA) jurisdiction are advised that dives described in the NAUI
Standards may be inconsistent with workplace safety rules. Employee
participation in activities that are inconsistent with current
workplace safety rules are not condoned by these standards.
Unless otherwise stated, course participants shall comply
with NOAA standards for oxygen time and depth exposures. However,
NAUI recommends a maximum of 1.5 PO 2 ATA for Technical
EANx and 1.4 PO 2 ATA for all other technical courses.
