Eliminating Hot Rocks:
The "Lock" can be used to deal with rocks that
contain much different minerals than the surround-
ing ground. (Referred to as hot or cold rock). This
procedure is the reverse of the previous example. To
eliminate hot or cold rock, balance DIRECTLY
OVER the problem rock and move toggle to
"Lock". This eliminates the ground response of the
rock and detects targets only.
The Beach position provides an extended ground
balance and tracking range to compensate for salt
water beach and alkali. Ground rejection against
salt water and alkali slightly overlaps the lower end
of the conductive target (metal) range and may
produce a very slight reduction in sensitivity to
conductive targets. The advantage and performance
improvements of rejecting saltwater, however, far
outweigh any loss. The Beach TRAC is not recom-
mended for normal conditions, only for saltwater
beaches and areas known to contain salt.
Remember- When hunting in the "Beach" mode-
balance in the "Beach" mode.
Summary - The On TRAC setting is recommended
for most searching conditions. Lock is used to hold
a ground rejection setting that is first established in
the On or Beach TRAC positions. Lock is recom-
mended for areas that cause detector instability due
to extreme ground conditions such as a lot of
decomposing man made iron. Beach provides
extended ground rejection range to compensate for
conductive saltwater or alkali conditions.
