Course Registration


Successful completion of the Deep Dive Operations Trainer (DDOT) program provides the Instructor with skills required to train their divers to safely and confidently plan and conduct open circuit, no-deco scuba dives on air for water depths in the range of 60' to 130'. This program teaches various methods to maintain proper descent rate and orientation during descent, participation in cognitive function exercises to assess subtle presence of nitrogen narcosis, controlling buoyancy on ascents/descents and teaching divers planned ascent profiles so that all divers remain within the no stop limits. Obtaining the DDOT certification allows the Instructor to teach the Deep Dive Operations program in-house and to mutual aid departments.
