Fished a small little Sunday tournament on a smaller lake around home. Just a few boats maybe 8 and could care less about the money involved in it. But when me and my buddy weighed in our fish that was last to weigh in they zeroed the scales for just us and we lost by 3 ounces. The guy who runs said the battery goes out and zeroed with tub but never did it before. I don't fish with those guys much and thought it was odd it happened. He had the winning bag and weighed in first. Plus he did it after he seen the fish we had. Anyone had somebody zero it for just one bag before?
