Diver0001 once bubbled...
This is on a bit of a tangent but personally I think it's bad practice to push or pull divers down on a descent, *especially* during training. I would submit that if a student is unable to descend then they need assistance in understanding why that's happening so they can solve the problem structurally. After all, isn't the goal of the training to teach them how to dive? Isn't controlling ones descent without assistance part of that?
R..
Diver0001 hits the nail on the head imvho
I can't speak for any other agency, but I know it's a hard fast rule that instructors (actually any dive leaders) are never to pull anyone down for any reason in mine. It's even taught to the students that you never "help" a diver by pulling them down. The list of reasons why you should never do that is long indeed.
Pulling astudent down to "fix" the problem is NOT fixing the problem... it's a lazy shortcut to an immediate but otherwise meaningless solution. If a student can't get down there's a reason... underweighting, hyperventilation, failure to properly vent the BCD or some other reason. The correct response is to determine the source of the problem and address that... not just haul them to the bottom. If I ever saw one of my DM's do that to one of my students it would be the last time that DM saw one of my classes, that I can guarantee.
imho -- regardless of anything else that may or may not have transpired, the simple act of pulling a student down was worthy of a complaint with or without a subsequent injury as a result.
