ground rejection. Settings
from -10 - +10 are available.
Tips - ON for most search
conditions, OFF for prospecting.

9. Trac Offset
Allows AUTOTRAC ® to track ground minerals
either positive or negative in relationship to the
correct setting (under, or over kill).
TRAC OFFSET allows the AUTOTRAC ® feature
to track the ground slightly more or less than what
would normally be considered perfect, mostly for
experts that prefer a slight offset.
A slightly positive offset can be used to enhance
the responses of small metals (gold nuggets) in
highly-mineralized ground. Positive is indicated by
a slight increase in threshold as the loop approaches
the ground in the all-metal mode. Discrimination
and depth may also be improved.
A negative offset may be used to eliminate particularly
troublesome "hot rocks" in areas that are
otherwise diffi cult to search. Negative offset is indicated
by a loss or slight decrease in the threshold
as the loop approaches the ground in the all-metal
mode.
10. Trac Inhibit
Prevents AUTOTRAC ® from tracking the ground
during target detection.
TRAC INHIBIT ON prevents the AUTOTRAC ®
feature from altering Ground Balance during the
detection of targets. This prevents the possibility
of tracking to the corrosion associated with most
metals. TRAC INHIBIT ON is recommended for
most searching conditions. Some metals do not
corrode (GOLD) and since tracking is extremely
important in high mineral conditions, the ability
to turn TRAC INHIBIT OFF is available. OFF is
automatically selected in the Prospecting Program
and is recommended for prospecting.
