PINPOINTING IN MOTION SEARCH MODE
Pinpointing in the search mode will take a little practice but
you may find that for most targets, it’s even quicker than the Zero
Motion Pinpointing Mode. Simply use the same procedure as in
steps 2 through 5 above. The only difference will be that when
you stop the coil over the target you will lose the audio signal.
You must keep the coil moving at least slightly to determine the
location of the strongest signal before you stop it.
1. For very strong signals, you may improve your
motion mode pinpointing accuracy by adding
one or more of the following steps:
a. Lift the coil until the signal is just barely heard.
b. Reduce the sensitivity level.
c. Increase the discrimination level.
d. Rest the coil on the ground and move it back
and forth very slowly.
2. For very weak signals try the following:
a. Move the coil closer to the ground.
b. Increase the sensitivity level.
c. Decrease the discrimination level.
d. Speed up the sweep rate slightly.
When the stem length is
properly adjusted, the 1225-
X is balanced for sweeping
in a tight semicircle. Always
overlap your sweeps by at
least 50% or you’ll miss a lot
of the deeper targets.
