the audio level decreases, raise the
searchcoil and rotate the Ground
Balance control a few turns to the right
(clockwise). Press the Tune button and
release. Lower the searchcoil again. If

Tune Button again and release. This is a
10-turn control; do not be hesitant about
turning it.
Continue this tuning process with the
controls until there is no change or only
slight change when the searchcoil is
lowered to operating height. You will
soon learn how to use this control to
achieve precise ground balance quickly.
Remember to rotate the control clockwise
when speaker sound decreases and
counterclockwise when the sound
increases. Also, remember that because
the knob is a 10-tune control, it might

ground balancing) mode. In this mode the
Gold Stinger will respond with an increase

mineralized ground, always operate in the
All Metal mode.
Mineralization can be balanced (canceled
out) in the All Metal mode by use of the
Ground Balance controls. To determine
if adjustment is necessary, lower the
searchcoil toward the ground, stopping
at a height of about two inches from the
surface. Make sure no metallic targets
are under the coil. When you lower the
searchcoil, audio level will increase,
decrease or remain constant.
If the sound remains constant, the Ground
Balance control is adjusted properly. If
