are generally found in highly mineralized soil so
this will be the search mode of choice for
prospectors.
NOTE:
In the AUTOTUNE mode, you will hear a slight
`threshold" hum at maximum sensitivity but not of settings of 8
and lower.
Target I.D. Search Mode
When the AUTO/I.D. control is set to I.D., the CZ-70 Pro has the
ability to identify many types of small targets, and depending
on the NOTCH discrimination settings, reject or ignore all of
them, most of them, or any combination of them. To better
understand just how your CZ-70 Pro 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.
Using the NOTCH and Arrow pads, set the
NOTCH control to accept all target categories.
Set the sensitivity at 5, the SALT/NORM control to
NORM and the VOL control to a comfortable
level.
3.
Ground balance the CZ-70 Pro as described in
the section on Ground Balancing (see p. 17).
4.
Hold the search coil about 2 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 get a response.
Keep in mind that for accurate target I.D., the
coil center must pass directly over the target.
5.
Note the response you get over the small
targets: For small iron or steel targets, the target-
I.D. marker will usually lock on the "iron"
category. Most pull tabs, foil, nickels and zinc
