DEPTH READING
Your CZ-3D will give you a quick and approximate depth reading
of coin-size targets, usually within an inch.
1. Place the search coil lightly on the ground at least
twelve inches away from your target area.
2. Press and hold the PINPOINT button.
3. Still pressing the PINPOINT button, bring the coil back
over the target and pinpoint its location by stopping
the coil over the point where you get maximum
pitch, volume and needle response.
4. Place the search coil lightly on the ground directly
over the target, and still pressing the PINPOINT
button, note the position of the needle over the
depth reading scale. For example, if the needle is
midway between the four inch and six inch marks,
your target is approximately ve inches deep.
You will quickly realize that the depth reading
procedure is just like pinpointing, however there is
one very important difference: When pinpointing,
where or when you press the pinpoint button is not
real critical. It is often desirable to “detune” your
target by pressing the button when the search coil
is very close to your target and either on the ground
or slightly above it. When taking a depth reading,
however, it is important that the coil be placed lightly
on the ground at least twelve inches away from
the target (or any other metal) before pressing the
PINPOINT button. Also, remember that while you can
pinpoint just about any size target, depth reading is
only accurate for coin size targets.

When your CZ-3D is properly “ground balanced,” it will have only
a minimum response to ground mineralization. Precise adjustment
of the ground control is critical. The higher the degree of ground
mineralization or sensitivity setting, the more critical it is. Once you
adjust it in either the Autotune mode or Target ID mode, you can
switch back and forth between the two modes without resetting
it, unless you increase the sensitivity level or go from dry sand
to wet sand or vice versa. You should also recheck your setting
occasionally as you search since ground conditions often change
rapidly.
If you have difculty ground balancing, try reducing your sensitivity
level or moving to another spot just in case you are over a buried
piece of metal. In some areas of high ground mineralization you may
not be able to use the “pushbutton” method.
1. Set your controls as follows:
GROUND = 10
DISC = 0 for normal use in target ID mode. (Set DISC
to “Auto tune” for deep search, all-metal Auto tune
mode.
SENSITIVITY = 10
MODE =ENHANCE
VOLUME = OFF
2. Hold the search coil waist high, away from any nearby
metal.
3. Turn the VOLUME control to 10. A brief bell tone is
normal when you turn the VOLUME control on.
If you’re in the Auto tune Mode, you’ll hear an audio
“threshold” hum. Lower the SENSITIVITY control until
you can just barely hear it.
4. If you’re wearing headphones, reduce the headphone
volume controls to a comfortable level when the search
coil is passed over a large, shallow target.
