Only because I'm and "older" diver (chronologically only), I'm not too worried about these threads that deal with re-certification. However, if I were a young buck diver just starting out or a middle age diver, I might have some concern. The big dive associations started the buffet of cert. courses we have spread out before us, and we all know the main reason they are there and heavily promoted---$. (I'm not talking about specialized courses like cave cert. etc.) Once the associations run out of certification areas, (and I think the only one left is "dry suit pee-valve cert.")what is the logical next step to keep the funds coming in? of course,---- re-certification. If the dollar looms higher than reason in our activity, the future dive industry will definitely shoot itself in the fin if ever OW or AOW is mandated to be renewed every 3, 5, or even 10 years. And don't you believe that they haven't already thought of it. Most of you on this board have been raised under the shadow of all of these certification levels and areas and it seems quite normal to you, but I believe even you would buck the notion of OW re-certification.----or maybe not. So, NO; I don't believe Rescue Diver cert. at the recreational level should be mandated to renewal. My $.02
