I know. Just playing along
Agreed. It is just difficult, but possible, to find an instructor who teaches at that level for other agencies, but trains them in the equipment that they own/dive in. I get why GUE doesn't bend on that. I think RAID's course is probably the closest to it, but without the equipment requirements.
I think requiring that all open water courses from the start, as some instructors do (unfortunately not the majority) neutrally buoyant and trim would solve a lot of problems. The overweighting issue would finally be consistently addressed. But that is beating a dead horse. We've been beating that poor horse's corpse for so long that all the flesh has decomposed and the bone is being pounded into dust.
