Figure 26: Determining Target Centre

NOTE

An operator can confirm that the centre of a target has been located

by moving the coil slightly, in any direction, and returning to the

centre. In doing so the volume of the Threshold Tone should

decrease from maximum as the coil leaves the centre and return to

maximum as the coil returns to the centre.

5.6 Multiple Targets. There may be occasions when an

operator will encounter multiple targets. For example, small anti-

personnel mines may be laid in a cluster, or a large anti-tank mine

may be surrounded by smaller anti-personnel mines or booby-traps.

Regardless, the pin-pointing procedure for the F3 can be used to

effectively map a suspicious area as follows:

a. STEP 1 Mapping the Target

Using the procedure described in Section 5.5.a, an area

enclosing the multiple targets can be mapped.
