Figure 27: Mapping Multiple Targets
NOTE
To an experienced operator the shape of the mapped area can
indicate whether multiple targets may be present.
b . STEP 2 Determining the Centre of Target

The pitch of the Threshold Tone will rise or fall depending on the
combination of metals or the composition of metal in a mine. This
means that, in some instances, experienced operators may be
able to identify one mine against another (Figure 28).

By slowly moving the coil across the mapped area, it may be
possible to detect tonal differences indicating multiple targets.
**WARNING**
The volume from a large target may mask that of a small
target if the small target is located very close to the large
target.
