tips for Searching in Different
environments
There are many factors which
influence the sensitivity and accuracy
of detecting objects, including the
angle, depth, size and oxidation
of the target object. Various soil
or seawater conditions, and also
electromagnetic and electrical
interference surrounding the target
can also affect readings. Other metal
detectors in the area will also cause
interference, so when there is more
than one unit in use, be sure they are
at least 10 yards apart. Some ways to
help increase success are:
1.
If there is interference from similar
metal detectors in your searching
area, lower the SENS setting to stop
the interference.
2.
If there is interference from electrical
cables, TV, radio, or other electrical
devices in your searching area, lower
the SENS setting.
3.
When searching in highly mineralized
areas, the unit may sound even if
there is no metal. Lower the SENS
setting, set the DISC to high and
increase the distance of the Search
Coil from the ground until the false
signal disappears. To set the DISC
setting, place a test metal object
in highly mineralized earth or wet
sand and adjust the setting before
beginning.
4.
When searching in a trash area, set
the DISC to the middle setting so that
the unit can reject most invaluable
metals such as nails, bottle caps,
cans, and small pieces of iron.

5.
Move all metal digging tools when
searching.
6.
The SENS level is generally opposite
the DISC setting. The higher the
sensitivity level is, the worse the
discrimination will be. You can
lower the sensitivity to have better
discrimination.
