No clue who Dr Ben is - might be more of a European presence.It's mostly Dr Evil (Doctor Ben he's called I think?) and people like that. The front-faces of the 'brand' GUE that annoy me. I am sure their courses are great in terms of quality. I just don't feel like signing up because they don't seem to be happy to be diving... So - with me at least - they have very ineffective marketing that gets them 1-0 down.
There are TDI instructors/divers I dislike. There are PADI instructors/divers I dislike. There are PSAI instructors/divers I dislike. And there are GUE instructors/divers I dislike. I don't fault the agency for the fact that I don't like these people - especially when there are many other amazing people that I do like associated with each agency.
I regularly see comparisons of TDI Intro to Tech to GUE Fundamentals and while they may look similar on paper, having taken both, Intro to Tech was nowhere near the class that Fundamentals was. In my small group of diving friends I know of multiple TDI instructors who didn't earn technical endorsements on their first attempt at GUE Fundamentals (and remember, thats GUE's Pre-req - not their instructor standards!) And of those who took the class, all but maybe one (bruised ego) would say it was one of the best classes they've taken and wholeheartedly recommend it to others.
Personally, I'd be jumping at the opportunity to take a course with JP Bresser @ Scuba Academie!
