Useful information
When attempting to recover targets, you need to dig a hole large enough so that the search coil in use can get inside that hole and then see what the detector indicates.
On some soil, not on all soil, the MP V3 may give a positive signal above empty potholes when the search coil is swung at the recommended level above ground.
How to recognize a signal from a hole vs a target in the hole
Holes
Empty holes can be recognized as such if the search coil is passed close to and over the hole slowly. While doing so observe the reaction of the detector.
A hole will give a reaction exactly when the search coil (the coil overlapping area) goes over the center of the hole. Empty holes will not produce signals if the search coil overlapping area is out of the hole perimeter.
Target
If there is a metal target in the hole, the search coil will pick it up before the overlapping area of the coil is on top of the hole.
Procedure to prevent an empty pothole signal
- Place the search coil static on the ground on one side of the hole, not overlapping the hole perimeter.
- Drag the search coil slowly across the hole and backwards, then the empty hole will not produce signal response when the coil is on top of it.
