68 - Garrett Metal Detectors
Highly mineralized soil can occasionally
result in improper target size/depth infor-
mation. Raising the coil an inch or two
as you scan over such soil is sometimes
helpful. Encrustation or patina may also
affect conductivity of the target, resulting
in improper classification.
Using Search Image
Experienced treasure hunters prefer to use
the GTI 2500 with the Search Image aid
turned ON, providing a constant display of
size and depth information. Because sizes
and depths of targets may seem to change
erratically until the coil is scanned directly
over a target, the following recommenda-
tions are offered:
Always remember that you have two
basic information sources concerning your
target the Upper Scale Target ID cursor,
which reports conductivity, and the size
and depth information that is shown on
the Imaging Grid. These reports should be
considered independently. When a target
is encountered, consider it initially based
solely on its conductivity as indicated by
the Upper Scale cursor which you will
