After setting 4. grounD the Tool is
ready for the soil type at that particu-
lar site. It will not need to be reset
until you move to a new location.
adjusting DiScriMination
Discrimination is the Tool’s ability to
differentiate between types of metal. This
setting determines whether the detector
will distinguish between different types of
ferrous and non-ferrous metals. If MoDe
is set to tr2, start with DiScriMination
set to mid-range. While the Tool is being
used, adjust DiScriMination to the best
position. As you set it higher, the detector
becomes more sensitive to the differences
between large aluminum and gold pieces,
for example, but other valuable items such
as coins and small rings, might be over-
looked.
As you set DiScriMination to
higher levels, the detector first does not
detect small pieces of silver paper, then
thick foil, and finally metal objects like cola
pull tabs. Each time you change areas,
you must reset DiScriMination.
False Signals and Detection Hints
As you sweep the search coil back
and forth over the ground surface, you will
recognize the difference between signals
that occur at random and signals that
are stable and repeatable. The key is to
dig only for those targets that produce a
strong, repeatable signal. This will prevent
you from wasting time focusing on trash
induced signals.
No metal detector is totally accurate.
Many conditions influence the success of
metal detection. Among the factors that
influence results are the angle at which the
object rests in the ground, the depth of ob-
ject, the amount of iron the object contains
and the size of the object.
To accurately pinpoint a target:
Once the detector detects a target
1.
that is buried, continue to sweep the
search coil over the target in a nar-
rowing side-to-side motion.
Stop the search coil directly over the
2.
spot on the ground. Then move the
search coil straight forward away
from you and straight back towards
you. Make a mental note of the exact
spot on the surface where the detec-
tor beeps. Repeat these steps in
an X pattern. The target should be
directly below the X at the area where
the loudest response is heard.
