Ground Balancing In The Field
Ground balancing is not a difficult procedure, but it is critical if you
desire maximum depth and stability. It is especially important if you plan
to find deep relics or prospect for gold nuggets.
No matter how or where you will be hunting, or whether you will be
hunting in the All Metal or Discriminate Mode, you must tune the ground
balance for the area that you will be hunting. If you fail to ground bal-
ance for every site, you will not be working at the peak of your detector's
performance and may lose both depth and sensitivity.
To ground balance in the field, we will start by assuming your detector
is turned off. This will be the normal condition of your detector when you
start hunting. Ground balancing can be done at any time while you are
using the detector. It is not necessary to turn the machine off each time that
you ground balance.
Start with the controls in the following positions:
1) SENSITIVITY on OFF.
2) MODE in the ALL METAL position.
3) All other controls will be set during the ground balancing proce-
dure or are not applicable at this time.
Turn the detector on by rolling the SENSITIVITY knob clockwise to
about 9 or 10 on the dial. You will
hear a quick double beep to let
you know the detector is operat-
ing. Next, adjust the THRES-
HOLD knob until a slight, steady
hum is heard. The machine is
now ready to be ground bal-
anced. Next, find an area that has
no metal targets in the ground,
as this may give false readings
while in the ground balance pro-
cedure.
As shown in the photos, raise
your searchcoil about 6 to 8 inches
off the ground. This is high enough so that the detector will no longer read
the minerals in the ground. While listening to the threshold sound, lower the
searchcoil to about 1 inch off the ground. As the coil is dropped, the detec-
