Although there are BSAC members who trained with other agencies, BSAC prefers members to take BSAC courses. We provide training from beginner through to Trimix (both open circuit and CCR), instructor (for those who want to put something back into the club), plus a whole range of specialties (like Diver Cox’en, O2, AED, archeology, marine live identification). It’s down to the individual to procure the training they want to do the diving they desire, not the club.There are dive clubs in the US--don't get me wrong. But I believe most are not affiliated with a local shop. Shops sell trips, and dive clubs go on trips, but I don't recall seeing any affiliation between a local shop and a club (not that I pay attention to these things--I'm sure club/shop affiliations exist). Dive clubs are just not that prevalent in the US--relatively few and far between. What appeals to me about BSAC--of which I admittedly know not all that much--is that there is a unifying organization over all the local clubs, and there is a standard training progression (though apparently BSAC members can be trained through other agencies). Here in the US, clubs seem to like to do their own thing, and I'm not sure having a national umbrella organization would appeal to us individualistic Americans. Our individualism could be a reason why the very idea of joining a dive club is not that popular.
A club system makes a lot of sense for an island nation. Surrounded by centuries of wrecks. And cheap flights to the Red Sea!
The challenge for a U.S. based club would be getting instructors, plus our Liability insurance isn’t available to North American citizens.
