Tap the last few inches of cable where it enters the coil and see if it gives a low tone false. If so, it could be a short in the coil.

Also the coil may be over an underground cable or wire, and it doesn't beep constantly, it will beep once every couple of seconds or so, and also while standing still, that coil will go really deep.

As above it can also be a short in the coil.

There is one more option, it could be the detector it's self. Has it been in a hot car for more than a couple hours? Has the head unit ever been wet in rain or wet grass? Have you dropped it before?
All of these things can mess up the detector and cause it to not work right.
