Actually, in private (nobody else is reading this, just you and me) I happen to agree: I feel responsible for the group I am leading and it can sometimes be an unnerving situation.:blinking:I believe the DM is responsible for the safety of the group he is leading, especially of they are relatively inexperienced. If I knew enough not to do what the DM says is OK, I wouldn't need him in the first place. You seem to be saying that it's fine to go through the training and certification where you taught to follow the briefing and DM instructions, but if they are wrong , it's your fault.
However, I am not responsible for your actions legally although I may be responsible legally for what I do or do not do in a given situation.
The reason that we follow agency standards is to protect ourselves legally. The balloon goes up, we followed SOPs (that's been pretty standard in any line of work in my life, not only diving).
On briefing and instructions, we try to give a clear briefing and to run through basics quickly and clearly (see how flight attendants, do it?) it's up to you to pay attention or not and make your dive plan with your buddy within the general overall dive plan that I outline.
For better or for worse this is recreational diving. That means if you want to go off with your buddy and do your own thing, that's your business. If you want to stick close and have special attention, let me know quietly before we get anywhere near the dive site and you will get it. No extra charge, quite the contrary, it's a pleasure. We (DMs) like to feel useful.
By giving me your input you assist me in making a better plan for all and looking at alternative buddy pairs (for those who don't have one) or dive teams.
We could talk about knowing enough or not to follow or not follow the DM in another post?
