I've had my pro 73 for almost a week, and it looks to be working okay. However, the only time I hear it beep is when I'm near a automatic door, or when there is really no police. I have passed a few police (university police, city police, even state trooper) and it has not beeped even when I am right next to them. Is my detector broken or defective? I bought an open box model on amazon. It seems that all bands are functioning properly though..'
thanks in advance!
