Maybe what we you are dealing with is someone who has had some DIR_F'ed diver to deal with in the past. Forgive me but I read a little of it in your tone- I might be wrong and if so, I apoligize but go with me a little. Being a DMC, you should be at the level where gear does not matter, you should be able to dive any BC you are handed with equal ease, instead of being excited about working with students you are "bummed out" about what BC you are wearing. In a later post you said he made it a point to tell you he did not care about DIR nor want his students given the impression a BP is safer- again sounds like he has delt with a DIR-F'ed diver before and you were at least giving the impression he may have one on his hands again. While I don't necessariliy agree with you not being able to use a BP I can see why an instructor would want to head off a DIR-F'ed type conversation in his class. I DM a lot and do feel students need to see a wide varity of gear, so do our instructors. In confined water, we all dive standard jacket BCs and standard octs, in OW we dive the gambit from jackets to BP/wing/long hose and pretty much everything in between. I even throw in a double hose reg (modified so it does meet equipment requirements) on occasion just to mix it up and we go out of our way to point out the differences.
Ease off the coolaid, put on the BC and learn to make it look as good as you look in your BP/wing and show them what a good diver looks like.....one who is in control of his gear, not the other way around.
No offense taken. I don't have a problem diving with a jacket bc, I just don't like it and therefore bummed out.
