I went to a very large dive center in South Florida last year with a guy who wanted to start diving, and they would sell him all the gear he needed but would not fill tanks. The sales clerk asked if he'd ever done any diving at all, and he said yes, he'd even been certified, at a Caribbean resort, in like 1986. She looked in her computer at the PADI site, and sure enough, the certification popped right up, and he was good to go with anything he wanted to do. He told me right up front that he was no more qualified to dive than a raw beginner -- the resort certification had involved pool training and a small number of open water dives, and he did okay with them, but had never dived again, not once, and never owned any equipment other than fins mask and snorkel for vacation beach diving. Anyway, I was kind of shocked that he was good to go some thirty years after really shaky training at a resort, but he was. (He bought the gear and went on to a regular training course, because he was no fool.) I think you can get pretty good training at PADI centers and other certifying centers, but you have to keep in mind that the instructors can't just pour knowledge and experience into your head, you actually have to learn things, and youtube videos ain't the same thing as time in the water.
