But the instructor with thousands of dives and thousands of students should allow a confrontation from a 60 dive DMC?
..... snip ..... The original post was that a DMC SHOULD have confronted an instructor while he was going through his DMC class.
Al, you're getting hung up on semantics of a word that the OP never used. The op asked if the DMC should have "spoken up". It wasn't until later that someone ....checking.... oh it was guy who is trolling you.... used the word "confront".
I think the OP had a good question. Should DMC's speak their minds?
Answer: unequivocally, YES.
If nothing else the process of discussing it will be good for helping the DMC build a framework/context (BoulderJohn called it "calibrating")
Lots of bad instructors out there along with lousy DM's and lousy divers. As I said before interrupting the learning process is not the way to go. I never said to be quiet forever, just in front of the open water students. If you don 't get that Mr I have 100 dives then I give up.
The OP also never mentioned anything about 'interrupting' the instructor or disrupting the lesson. I agree with you that it should be done discretely while students are not around but even instructors who value the DM's input have said this. There's really no discussion about it, when the lesson is on, everyone is focused on the task. After the students go home then the "speaking up" can take place. There is only one person in this thread who has said otherwise (IIRC) and he's just busy pressing your button.
