Rob,
What other questions did you ask prior to selecting an instructor?
My initial questions focused on schedule and teaching philosophy. Sure, there's a lot to be taught in any kind of technical course, but I'd just as soon not spend hours upon hours in a classroom and then hit the water trying to remember everything that was covered in the classroom. So I want to know the course schedule and what we'll be doing. One of the best courses I took was a wreck course that took place at a picnic table next to the water. We discussed the didactic part, then went diving. We only talked about what was applicable for the next dive.
I then provide a list of my gear and ask if I need to purchase anything else prior to the course. I already know what I need, so this lets me know if I'm dealing with someone that knows what he's doing or if I'm dealing with someone that's stuck on a particular brand (I'll usually leave a piece of gear off the list and then ask about different brands). I also like to take courses from independents. These instructors are trying to sell themselves, not the gear in their store.
I ask about course fees. I know what the average rate is. I crossed an instructor off my list once because his fees were less than half the going rate - you get what you pay for.
I ask about experience in that particular type of diving - How many cave dives have you logged? Goes along with the next question. You can figure out how many were training dives v. experience dives.
How many cave divers have you certified? And more importantly, how many have you not certified due to insufficient skills or wrong attitude? I really liked the response the instructor I chose provided (from saved e-mail):
"Since I log by courses and not by divers, number of courses is easier.
Prior to moving to Florida, I taught Cavern only. Since moving to Cave
Country and pursuing cave and mixed gas training as my occupation, I have
taught slightly more than 160 overhead courses with approximately 50 of
those at Full Cave or above (specialties). While each diver is judged on
individual merit and ability, I require a higher level of performance as
the diver progresses through the overhead curriculum. By estimate only,
somewhat less than half complete Full Cave, DPV, etc. on their first
attempt. I "fail" very few, but do often require additional work prior to
completion. A failure occurs when I advise a diver I am no longer willing
to work with him."
Based on this answer and the previous one, this instructor had logged approximately 800 experience cave dives.
Finally, a big part of it is the attitude in the responses. This instructor was just answering questions. He wasn't trying to be a salesman or coming across as cocky. His website gave me the same impression.
Hope this helps you.
