metal can then be interpreted easily by
the operator. Do not adjust the control
when the loud signal of metal detection
is heard.
Ground Balance
This control at the lower right permits
precise ground balancing of the detector's
circuitry in the All Metal Mode. This cancels
the effects of iron ground mineralization
when operating with the Master Control
switch set to the left at ALL METAL
and these controls are essential when
engaged in electronic prospecting.
Calibrated Discrimination
This control on the upper left offers full
control over the target discrimination
capabilities of the Scorpion Gold Stinger.
This control can be used when the
detector is operating either in the Motion
Discriminate or TR Discriminate mode.
When this control is turned to Zero,
detector circuitry is set at the absolute
calibrated point between metal and
1
mineral. Any increase in sound caused
by a sample tested at this level indicates
the presence of conductive metal. Ore
sampling is generally conducted in the
TR Discriminate mode with the control
first set at Zero and gradually advanced.
When hunting for coins, jewelry or other
objects in the Motion Discriminate mode,
this control permits the detector to reject
pulltabs and other unwanted trash.
Auto/manual Tune
This toggle at the left between the
Discrimination and Audio controls selects
Automatic or Manual tuning. Automatic
operation is recommended, especially for
the beginner.
retune
This small push button control near the
lower center of the Control Panel permits
the operator to retune the instrument as
desired when manual tuning is being
used.
