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.
