doesn't SELL any of this kind of gear.
The shop is the one who trained me originally and also the one I did my AOW through. I like them in general, but I don't care for their nazi-like attitude on pricing (which of course dovetails nicely with that of the lines they carry), nor did I appreciate the attempted lambasting on their boat when I was talking with another diver on board about my changeover (still in process at that point) to a BP+W + long hose. At the time I was diving a Knighthawk and "conventional" reg setup, but only because I had just gotten the BP and was spending pool time getting used to the differences.
The owner basically tried to tell me that diving a bungied backup was "dangerous" as I had to donate the reg in my mouth. I pointed to the Air2 she had sold me on the Knighthawk, and said "oh, so the rig you SOLD ME is dangerous, since I will be required to breathe THIS at depth and donate MY primary?"
She got REAL red in the face, and it wasn't a sunburn
I haven't dove their boat since, which is fine with me, since I have my OWN boat. Their loss; there are times when I can't get enough people who can dive to make it work to run my boat, but I'll be damned if I'm going to show up on their boat with a KNOWN unwelcome gear config, and I'm also damned if I'm not going to dive what I prefer, which is a BP+Wing+long hose, just for their grins and giggles.
The instructor in question is a cave diver - I've talked with her about her diving, and she's been at it for a long time. She is not a cave INSTRUCTOR (she is certified to teach cavern, but not full cave), and is one of the better divers I've seen around these parts. As instructors go, she's great - I have not one complaint with her in terms of her diving skills, or her ability to impart knowledge in a no-nonsense fashion.
I suspect that her bias in this matter is a matter of shop policy, but it doesn't matter really - if I want her to teach me, and I do, then I either accede or don't take the class.
I
do own the other BC, and I still have the short hoses, but it seems stupid to me to take rescue with an unfamiliar (I've been diving the BP+Wing+Longhose for essentially the last eight months non-stop) kit for me, then switch back to the other. Yeah, I can do it. But why?
I've heard that one of the things you have to do in Rescue in the pool is swim down to the bottom to your kit which has been dumped there and don it while wet, starting with only a bathing suit. I can do that. I've tried it in my pool. Once I get to the reg the rest is easy, 'cause I have air, and in fact with a long hose its EASIER since I have a LOT of hose to work with while donning the rest of the kit! No risk of getting the reg torn out of your mouth.
I've also doffed at the bottom of my pool and then done a free ascent. Yeah, my pool isn't real deep. So? What does depth have to do with it, other than getting to the reg on your first breath-hold dive from the surface?
I suspect that at the end of the day I'll blow off the class, since acceding to this is both silly in my opinion AND reinforces what I see as bad behavior on their part.....
