Pinpointing In The Motion Search Mode - Fisher M-Scope 1236-X2 Operating Manual

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 No-
Motion Pinpointing Mode. Simply use the same procedure as in
steps 2 through 5 on p. 14. 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.

NOTE:
Many targets within the range of your 1236-X2 will not be
detected unless you closely overlap your swings.
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.
1. Minimum Depth
a. Very slow or very fast sweep speed.
b. Discrimination set at 10.
2. Good Depth
a. Moderate sweep speed.
b. Discrimination set at 5.
3. Maximum Depth
a. Moderate sweep speed.
b. Discrimination set at 10.
