IN THE FIELD TECHNIQUES
hobby, you may want to dig all
targets at first. With practice in
the field, you will learn to better
discern the nature of buried
objects by the nature of the
detector's response.
You may encounter some false
signals as you proceed. False
signals occur when the detector
beeps, but no metal target is
present. False signals can be
induced by
interference, oxidation, or highly
mineralized ground soils. If the
detector beeps once, but does
not repeat the signal with several
additional sweeps over the same
spot, there is probably no target
present.
When searching very trashy
ground, it is best to scan small
areas with slow, short sweeps.
You will be surprised just how
much trash metal and foil you will
electromagnetic
(continued)
find in some areas. The trashiest
areas have been frequented by
the most people, and frequently
hold the most promise for finding
the most lost valuables.
Also maintain the search coil
positioned just above the surface
of the ground, without making
contact with the ground. Making
contact with the ground can
cause false signals.
