DEPTH READING
Your CZ-5 Quicksilver 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 five 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.
