When the TRACKING is active, the
Au GOLD FINDER
may produce a response when
passing over hot rocks. This reponse is due to magnetic/ferrous differences between the
hot rock and surrounding ground. As you verify the target (repeatedly sweep the search
coil over a potential target) and the target response disappears or significantly reduces,
TRACKING has automatically adjusted GROUND BALANCE to eliminate the undesirable
target.
TRACKING continually adjusts GROUND BALANCE as you detect. If you are detecting an
area with many hot rocks, the
Au GOLD FINDER
may not respond as TRACKING repeatedly
senses the hot rocks and continually fine tunes (eliminates) the undesirable targets. If you
are detecting an area and infrequently encountering a hot rock, the
Au GOLD FINDER
may respond to additional hot rocks since TRACKING is continually adjusting to changing
ground mineralization.
TRACKING is is recommended for use in areas with changing soil types and should not be
used simply to eliminate hot rocks as its use does impact detector performance (depth).
TRACKING does not eliminate metal targets. Consistent strong response when repeatedly
sweeping over a target indicates high probability of metal.
NOTE:
Because of the slight delay in TRACKING,
Au GOLD FINDER
may initially produce a
strong target response (i.e. one or two sweeps) as TRACKING fine tunes GROUND
BALANCE, response to undesirable target becomes weaker and disappears.
Tracking and Effects of Rocks
Au GOLD FINDER
can easily detect metal targets under mineralized rocks with proper
adjustment of settings.
In DISCRIMINATION modes, the key to detecting targets under mineralized rocks
(particularly positive rocks) is the proper adjustment of DISC FILTER.
For example, if the hot rocks in your search field can be detected when DISC FILTER is set
to five ‘5’, you should then set the DISC FILTER to six ‘6’. This enables a response for
desirable metal targets while eliminating response to hot rocks.
NOTE:
If you set the DISC FILTER too high, you will lose response for hot rocks and
desirable targets.
IMPORTANT:
The combined response created by the rock and metal target is lower than
the response of the desirable metal target by itself. In other words, detector response to a
small gold nugget under a mineralized rock may generate an iron response (i.e. low iron
tone instead of high gold/non-ferrous tone).
