F3 INSTRUCTOR NOTES

Minelab Countermine Division Safety Through Excellence

Edge Detection makes use of the coil’s consistent sensitivity around

its circumference to detect the edges of a target. To conduct edge

detection, the coil should approach the suspected location of the

target from a variety of angles.

As the coil approaches the target, the Threshold Tone will change

indicating that the coil is in close proximity to the target. At the

change of the Threshold Tone, the operator should mentally mark the

position on the ground, move the coil away, and approach the target

from another angle.

This process continues until the operator achieves a mental picture of

the target area.

P0627-B

**WARNING**

Extreme care must be taken when mapping the target to ensure that the

coil does not touch the ground (or any exposed parts of the mine) or snag

on any previously undetected trip wires.

For large minimum metal anti-tank mines, it is possible that the area

mapped out may be less than the actual area of the mine.
