OK, thanks.What I'm talking about is general equipment knowledge (how to set up kit) Bouyancy controll, and what I call "awarness" in the water (how/where you are in the water collumn etc).
Good point. I wonder if you see / there are more Americans who take up diving as just 'one of many' activities, and then pursue it only once a year. I have never seen country-specific statistics on 'certifications per year per hundred thousand population', but that might be revealing. Maybe, what you are seeing is that there are people in the US with the financial resources to do the certification, probably at a resort destnation to begin with, then dive again a year later, also at a resort. That kind of initial training and subsequent limited acitivity would not lend itself to proficiency.I'm talking about what I see at destination diving, and maybe it is the fact that many more americans are just 1 week a year divers, rather than more experienced.
