Pinpointing Procedure - Minelab F3 Compact Operation Manual

Depth of detection depends on target distance from the coil, not depth of the
target under the ground. Therefore, the coil should be swept as close to the
ground as possible to maximise detection depth (local Standard Operating
Procedures take precedence).
When a target is initially detected, an operator should stand in place and continue
to sweep the F3 Compact beyond the target in an attempt to find clear ground. In
doing so the operator will:
a. Immediately gain an impression of the size of the target prior to commencing
the pinpointing procedure; and
b. Confirm the target is not in close proximity to a second target thereby avoiding
a possible booby trap.
Minelab recommends a half coil (100 mm/4 in) overlap on successive
sweeps as an operator moves forward in a mine lane.

Pinpointing Procedure

The design of the F3 Compact makes pinpointing accurate and fast. The
F3 Compact's monoloop coil means there are no gaps in sensitivity around the
coil's circumference or across its surface. Pinpointing is conducted by first
mapping the target and then finding its centre.
