Depth Reading - Fisher M-Scope CZ-5 Quicksilver Operating Manual

TARGET IDENTIFICATION

DEPTH READING

Your CZ-5 Quicksilver will give you a quick and approximate
(usually within an inch) depth reading of coin-size targets.
response once you've pinpointed the target, then
you're over something that falls below the DISC
setting you've chosen and the CZ-5 is rejecting it.
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
is not real critical where or when you press the
pinpoint button. In fact, 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.
