Maybe I'm confused... but you seem to be saying it 'defeats the purpose' of AOW if the diver isn't an Advanced Diver? Or am I reading it wrong?
Why should Advanced Open Water make someone an Advanced Diver?
'Open Water' being a specific term applied to entry-level training, wheras 'Diver' encompasses the entire spectrum of sub-aqua activities...
When I have an above average OW student... I'll say "Hey, he's a really good open water diver". Nobody gets confused and thinks I'm stating he's a world-class diver. So, why does this happen with something so simple as the AOW course title?
