Can any one out there give me some advice I have been using a 4500 with mono coils and I keep getting a faint false signal when Im detecting. I have changed coils and adjusted settings but it doesn't seem to be making much difference.Thanks

Forky,We need more information;Is it when you bump something?Is it at centre of your swing or when you are far left or right?Are you sure you don't have any metal in your boots.Are you bumping the coil connection into the front of the box?
