If I have it set right so that I hear the slight pulse of the probe and go into the hole or even those at 3-4 inches I can hear a change in the pulse on dime or pennies and know it is seeing it at 4 inches or more, if it really make a difference it is within 2-3 inches and when it screams i know I am touching it or very close to the target.
I also notice if the battery is getting lower it is not as stable as a new battery is and seen where I had to change the freq on the UniProbe to run stable if using some detectors as it will interferre with the UniProbe. If the sound is cutting out only when switched to the probe it is probably a bad connection in the probe where it connect to the headphones. Now if it also doing this with the probe off and the detector on than it is probably in the cable that runs from the detector to the headphones with is a replaceable cable.
Hope it is a easy fix and know Detector Pro the maker of it will take care of you well.
