Link on the Socaltechdivers.com web site was pretty specific on gear which prompted my original question... Again, I will follow up with the references given.
SoCal Tec Divers - NAUI Technical Equipment Configuration (NTEC)
For purposes of safety, functionality, and uniformity of instruction, gear configuration during all in-water training activities must be the same for instructors and students. Standardized equipment rigging is critical to the safety, success, and effectiveness of technical diver training. The NTEC configuration is required for all SCTD courses.
