TSandM:
The instructor we were unhappy with had mocked us for doing a pre-dive equipment check, and had boasted of falsifying information on a dive log required by the ship.
All of these are behaviors I think are unprofessional. I'm sure people can come up with more. But I guess I'm getting at instructors who demonstrate behaviors when not teaching that they would find unacceptable if shown by their students.
Instructors who are there to enjoy a dive should not have to exhibit any special behavior, unless there is a rescue involved where I would expect them to do their best to lead or assist in that effort.
The things you list however are unacceptable for ANY diver, and less so for an instructor who is suppose to know better than most.
Falsifying a dive log is unethical and just wrong. Mocking other divers is rude, and uncalled for, unless you are diving with CBULLA and the FL Conchs!
I dive with instructors on a regular basis, and when they are NOT instructing I feel the need to allow them to enjoy the dive and NOT rely on them beyond the buddy role, or put them in an instructor role.
I dove with an instructor as an insta-buddy in the Keys. She was a bit hesitant to dive with me not knowing what to expect. I told her that we would relax, enjoy the dive, and I'd use less than 1000 lbs on the shallow reef, so no OOA worries. I think she was skeptical, but after 30 minutes into the dive she asked to see my spg, and at over 2500lbs her eyes widened, and we continued on.
After the dive she told me she mostly dives with students, and that our dive was the most relaxing and enjoyable dive she had so far in 2006. I think she really enjoyed having a buddy who treated her like any other diver, and after we were done she asked if I would like to join them (her hubby was also an instructor) next weekend.
Sadly I was leaving, but she gave me a card and her phone number, and said call us any time you get down to the keys. I think in this case the instructor discovered how much fun no stress diving is with someone who just treats her as a buddy.
