you many have encountered
multiple objects. If you are
new to the 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 electromagnetic
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 trashing
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 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. To make
searching easier in very trashy
areas, consider purchasing the
Bounty Hunter 4-inch Search
Coil (Radio Shack item 63-
3009 or 63-3014). The 4-inch
coil’s narrower detection field
can better distinguish between
two objects in close proximity.
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.
