Yes, but it seems (as I am not intimately familiar with it) that BSAC's open water course (called Sports Divers) is far more extensive than most mainstream agencies' open water courses. Give the model for quick and dirty for the bulk of the market (not judging, just reality), I am not sure that agencies are keen to adopt more thorough training. I'm not saying that as a critique of BSAC. Far from it. I just live with the reality of low standards and how to add to create safe(r), competent, and confident divers for my local area. Due to agency constraints, I can't teach open water divers to plan decompression dives.
