Pinpointing - Fisher CZ-20 Quicksilver Operating Manual

PINPOINTING

Target location is quick and easy using the pushbutton Pinpoint
mode. You do not have to keep the coil moving to get a response
in this mode.
NOTE: Large or shallow targets can give a wide signal when the
pinpoint button is pushed. This can make pinpointing difficult.
To pinpoint these large or shallow targets, find the edge of the
wide signal with the pinpoint button pushed. While over the edge
of the signal, release the pinpoint button and re-push it. This
automatically decreases the sensitivity and narrows the width
of the pinpoint signal. By repeating this procedure a few times
over the edge of the wide signal, you can narrow the pinpoint
signal and pinpoint your target.
1. Once the presence of a target is indicated by
the "beep-beep" of your CZ-20, simply move the
coil away from the target area, and with the coil
lightly on the ground or very close to it, press and
hold the PINPOINT button. (It doesn't matter which
mode you're searching in, Autotune or Target I.D.)
Edge of signal with pinpoint button pushed once.
Edge of signal with pinpoint button pushed and
released three times.
2. As you bring the coil back into the target area,
still pressing the PINPOINT button, the audio volume
and pitch will increase.
3. When the pitch and volume are at their highest
points, stop the coil and move it forward and
backward a couple of times, again stopping over
the strongest response. Edge of signal with pinpoint
button released and pushed again.
To pinpoint a large or shallow target, find the edge
of the signal with the pinpoint button pushed. Then
release the pinpoint button and re-push it. This
automatically narrows the width of the signal by
slightly decreasing the sensitivity of the search coil.
4. Repeat one more time, side to side and then front
to back, keeping the PINPOINT button pushed in,
stopping over the spot where you get the maximum
volume and pitch.
