    This is the background sound produced by the detector. When a target is detected, the Threshold changes in volume The Excalibur II will perform at its best when the coil is (and pitch in Disc mode). Listen to the Threshold carefully.

    Pinpointing Locating the Target The exact location of a target can be located by Pinpointing. 1 Switch the detector to Pinpoint mode. 2 Once the approximate target location is known, move the coil slowly over the target. The audio tone will increase in volume while moving towards the target and decrease in volume as you pass it.
