NAUI Tech basically just copied GUE's gear config and a lot of the procedures.
This comes down to an Agency issue and a semantic argument over what gets called DIR.
What is the motivation behind trying to figure out what the DIR 'label' applies to, anyway?
Does calling a NAUI Tech diver 'DIR' or 'not DIR' change anything about the way that diver actually dives?
As far as GUE is concerned, they're never going to accept any cross over training from another agency, because they want to make sure to enforce their own standards, and it doesn't matter if you call divers from other agencies 'DIR' or not.
So, GUE invented all the techniques they teach?
