This past weekend I found out that a TDI instructor I know did not know how to set up a set of doubles. He can teach advance nitrox, stage decompression, trimix and dolphin rebreather, but he didn't know how to set up doubles. I don't understand how he can teach all of these classes but not know how to set up doubles. How common is this?
