Anyone using this meter? I'm new, bought this to try and save a buck. Unless I'm doing something wrong or there's some info I don't have I think I should have spent another buck fifty and got a bird dog. I've never gotten a lock on sat 119, and I get a lock on sat 110 in several locations. I'm new in the business so maybe I just don't know what I'm doing, but it seems to me the guys with sat buddies or bird dogs swing the dish once and never go back up on the roof. Half of the time the dang thing gets me on, the other half I wind up on the roof on the roof on the cell phone to the customer helping me aim the dish, any input appreciated.
