I've had a silver umax for about ten years. It's beat to hell. Anyway,its been acting funny so I sent it to Tesoro. I received a call from Rusty the other day,and he explained what he did too it,then we talked for 15 minutes bout detecting and detectors. Would have been longer,but he caught me working on the roof. Tesoro and Rusty are class acts!! Oh,and when I reciebed it back,he even replaced the missing battery door!
