The quality of tech instructors...
My first tech classes were with an instructor who I don't think has ever done a real dive in his life. If he did he would surely die and on most of the training dives he stayed on the dock where he was safe. LOL My second day in doubles, my wifes first dive in double and we did 170 on air with the instructor on the dock! ok, we were stupid too but we didn't know any better than to trust the instructor. My wife later redid the class with another instructor and we both got an education.
With some agencies it's getting easier and easier to become a tech instructor. Oh, you need to have had lots of classes but 25 stage decompression dives? I've seen divers at the quarries doing a bunch of 131 ft bounce dives to qualify.
By all means, pick an instructor with real and ongiong experience. Having the card alone isn't enough and that goes double for instructors and triple for tech instructors.
