™
FIELD OPERATIONS
As you walk, scan the searchcoil from side to side
in a straight line or slight arc pattern. Keep the coil
level and at a constant height of one or two inches
above the ground while you scan at the rate of two
to five feet per second.
When scanning, do not hurry. Be methodical.
Overlap each scan sweep at least 25 percent of
the searchcoil’s width. Wear headphones to avoid
ambient noises and to concentrate on scanning.
When you are searching in the ZERO Discrimination
Mode, every metallic target will produce an audible
sound.
