People seem to have different interpretations of what a "rescue" skill is. Much of the discussion over the years has revolved around PADI making a choice to delay teaching the CBL until the Rescue course while some people, and some agencies, seem to prefer putting this into the OW course.
What I see is that we'll never tire of debating which choice is the right choice. I don't hear of a lot of accidents involving rookie divers where the conclusion of the accident analysis was, "if only he had known the CBL".
What I *do* hear is a lot of accidents involving rookie divers (and some experienced ones) where the conclusion was, "if only they had watched their instruments" or "if only they had dropped their weights".
Those skills *are* in the OW course and if you ask me PADI isn't entirely unjustified in putting the emphasis at the OW level on the skills that will help to avoid or mitigate immediate problems that the diver is having *before* it gets to the point of panic, drowning or needing to know a CBL.
There is value in the "big" rescue skills, of that there can be no doubt, but making sure rookie divers focus on their own diving first doesn't seem like such a stupid idea to me. Nevertheless, it is a choice and as such we'll debate it until our sun turns into a red giant and the oceans boil away to mist.
