Ok I went back today with a valid serial number....don't ask but I got one. A different sales lady (no one I knew was there). Anyways she didn't even ask for the number, but said the dive strap was on backorder, she ordered one last week. She said about 3 months if I order today. I'm going to call the next closest AD tomorrow to confirm or maybe I'll get luck and they have stock. It's a long drive but.....I could make a trip of it I guess
