Dang jlargent, are you in my head or what?
I'm independent whenever i can be but have THREE different sets of gear, two for two different LDS's i teach for from time to time and one for myself. Due to the equipment intensive nature of OW training it's pretty hard to independently teach without investing & maintaining mucho gear. LDS's know that & hold it over your head. Your right, most LDS's i'm familiar with take gear sales MUCH more seriously than instruction. Heck, with larger classes i'm forced to pay for necessary added pool time out of my own pocket because one LDS says another instructor only takes this many (not enough) hours. If i didn't have a good day job that would not be an option.
I agree with c-cards requiring some kind of renewal to remain current. As stated earlier, i think most of the problems out there with skills have to do largely with lack of diving after training. Try as they might well over 50% of the divers we certify don't dive much after certification no matter how hard we extoll the virtues of doing so. There is money to be made to help sustain the industry, by performing Q&A training for divers who are already certified. It would go a long way to solving some of the ills out there.
And for those of you who think it is evil for anyone in the scuba industry to actually make money from it, save your comments for someone who will argue with you. I won't. Cutting costs for classes is one of the things that got us to where we are today. The cheap quicky class is NOT the answer
