When I was teaching, DSMB deployment was part of the AOW curriculum. We'd cover the gear and its uses during the classroom part, and it would be part of of one of the dives ... usually the one where we used the earlier part of the dive for gas consumption measurements. The exercise provides practice for several skills, actually ... buoyancy control while performing a task perhaps one of the more important ones. But there were other lessons ... like what happens to line underwater if you don't maintain a slight tension in the line (aka, "underwater macramé"). We used 3-foot bags and spools. I'd have the students shoot the bag, then I'd pull it down, release the air, have them stow it, and repeat a few times. After it looked like they were getting it clean, we'd ascend up the line, winding up the spool as we went. It taught them how to use the line as an ascent line, and gave them more practice managing their buoyancy while they were busy thinking about some other task. Overall I found it to be a useful skills practice for more than just the act of deploying the SMB.
We'd typically do the exercise at a depth of around 30 feet, and spend maybe 10 minutes doing repeated deployments before making the ascent ...
