PINPOINTING
PUSHBUTTON PINPOINT MODE
Target location is quick and easy using the push-button Pinpoint
mode. You do not have to keep the coil moving to get a
response in this mode.
1.
Once the presence of a target is indicated by the
“beep-beep” of your CZ-3D, 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 ID.
2.
As you bring the coil back into the target area, still
pressing the PINPOINT button, the audio volume and
pitch will increase and the meter needle will swing
to the right.
3.
When the needle, 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.
4.
Repeat one more time, side to side and then front to
back, keeping the PINPOINT button pushed in and
stopping over the spot where you get the maximum
volume, pitch and meter reading. Your target should
be directly below the center of your search coil.
With a little practice, you’ll find that you don’t even
need to look at the meter unless you want a depth
reading.
NOTE
:
For quick and accurate pinpointing of strong
signals from large or shallow targets, push and hold
the pinpoint button with the coil very close to the
approximate target area. This will “tune-out” most of
your target so you will receive a response directly over
it. You may also try reducing the sensitivity level and/
or raising the coil so you can barely hear the signal.
For very weak signals, make sure you press the
PINPOINT button with the coil completely out of the
target area. You may also try moving the coil closer to
the ground or increasing the sensitivity and volume
levels.

AUTOTUNE SEARCH MODE
Set the DISC control to Autotune for a very sensitive, wide-scan, all-
metal, motion search mode. Since this mode responds to all metal
targets and does not have the ability to identify or reject targets, this will
probably not be your normal search mode.
The Autotune mode does have some advantages however which
make it useful to use in at least two situations:
1.
Non-Trashy Areas.
Since the Autotune mode has a wider
scan than the ID mode, you’re less likely to miss a good
target when using it. Search in the Autotune mode until
you find a target. Pinpoint the target using the PINPOINT
button and then switch the DISC control to “0” to identify
it. The DISC control is positioned so that you can switch
back and forth between Autotune and “0”.
2.
Highly Mineralized Soil or Sand.
The Autotune Mode
is recommended for black or gray sand beaches or
highly mineralized soil. Under these conditions it may be
necessary to lower the sensitivity level and sweep several
inches off the ground. Gold nuggets are generally found
in highly mineralized soil so this will be the search mode
of choice for prospectors.
TARGET ID SEARCH MODE
When the DISC control is set in the 0 through 6 position, the CZ-3D has
the ability to identify many types of small targets and, depending on the
discrimination level, reject or ignore most of them. To better understand
just how your CZ-3D responds to different targets, try the following:
1.
Scatter some sample targets such as coins, rings, pull
tabs, nails and foil on the ground at least 18 inches apart.
Include some large targets as well; jar lids, soda cans,
etc.
2.
Set the DISC control at “0”, SENSITIVITY at “5”, MODE
at ‘ENHANCE’, VOLUME at “10”. If you’re wearing
headphones, reduce the volume to a comfortable level
when you are over a large target.
3.
Ground balance the CZ-3D as in the “Ground Balance”
procedure.
4.
Hold the search coil about two inches above and parallel
to the ground and move it slowly back and forth across
each sample. Remember, the coil must be in motion to
