IN THE FIELD TECHNIQUES
Swing the search coil slowly,
overlapping each sweep as you
move forward. It is important to
sweep the coil at a consistent
speed over the ground as you
search. After identifying a target,
your sweep technique can help in
identifying both the location and
the nature of the target. If you
encounter a weak signal, try
moving the coil in short, rapid
sweeps over the target
zone; such a short rapid
sweep may provide a
more
target identification.

Crossing the target zone with
multiple intersecting sweeps at
multiple angles is another way to
verify the repeatability of the
signal, and the potential of the
buried target. To use this method,
walk around the target area in a
circle, sweeping the coil across
the target repeatedly, every 30 to
40 degrees of the circle, about ten
different angles as you walk
completely around the target. If a
