This will probably be your method of choice in all but the most
difficult of ground conditions. It’s fast, easy and accurate. You
can use this method in either the Autotune or Target-I.D. mode.
1. With your controls set as in the “Turn-On”
procedure (GROUND control at “10”), hold your
search coil parallel to and 6 to12 inches off the
ground. Press the PINPOINT button and hold it until
you’ve completed step 2. Make sure you’re at
least 3 feet away from any metal objects.
2. Continue pressing the PINPOINT button as you
lower the coil to the ground. Keep your thumb on
the PINPOINT button, and starting at “10,” rotate
the GROUND control clockwise until you hear an
audio tone. Then back off to the exact point where
the tone disappears. Release the PINPOINT button
and you’re ready to search.
3. Always ground balance your CZ-20 in the areas
you intend to search, whether it’s on land or
underwater.
NOTES:
1. If you get an audio response as you first lower the coil with
the GROUND control at “10,” you’re probably over a piece
of metal. Move and try again.
2. If you get a sudden bell tone that is not preceded by an
increasing audio response as you lower the coil, you’re
probably in some very highly mineralized soil or sand. In this
case, it’s best to use the “bobbing” method, paying particular
attention to the notes under paragraph 7.
3. If you don’t get any audio response, or just a very faint one
as you rotate the GROUND control from “10” all the way to
“0,” you’re probably in an area where there’s very little ground
mineralization. Just leave the GROUND control at “10” and
begin searching.
