Target Pinpointing (No Motion) - Fisher F2 Operating Manual

TARGET PINPOINTING
After you have identified a target using a motion mode of detection, press
to identify the target's exact location. This technique can yield more
information about the target's shape and size and also find its exact
location to facilitate excavation.
Using :
1. Position the searchcoil just barely off the ground, and to the side of the
target.
2. Press and hold
searchcoil away from the ground makes the ground signal go negative,
so the machine is silent.
3. Now move the searchcoil slowly across the target, and you can locate it
by the sound. The target is located directly under where the sound is
loudest.

and raise the searchcoil about 2 inches. Lifting the
Narrow It Down:
1. To narrow the response further, position the center
of the searchcoil near the center of the response
pattern, but not directly over the center.
2. Release, then press and hold again
3. Repeat this narrowing procedure to narrow the field of
detection further.
Note: Depth indication is less accurate after
narrowing.
COIL DRIFT

to gain or lose sensitivity. Periodic retuning of the
