FINE-TUNING THE DETECTOR
After you become familiar with how your detector works, you can
fine-tune it to make it more selective in what it finds.
Discrimination is the detector’s ability to differentiate between types
of metal. The detector’s DISCRIMINATION setting determines
whether the detector will distinguish between different types of
ferrous and non-ferrous metals.
You can set DISCRIMINATION to minimum (fully counterclockwise),
to maximum (fully clockwise), or anywhere in between. With
rotating clockwise, the detector first discriminates iron, then pull
tabs and nickel. When set the DISCRIMINATION fully clockwise,
silver still can’t be discriminated. When metal under discrimination
is detected, the pointer moves to the left and the surround LED
indicates by red light. And the pointer moves to the right and the
LED indicates by blue light(metal object set by DISCRIMINATION
not to be detected)
Note: Each time you use the detector in a different area, or
DISCRIMINATION is adjusted, you'll need to re-tuning the detector.
FALSE SIGNALS
Because your detector is extremely sensitive, trash-induced signals
and other sources of interference might cause signals that seem
confusing. The key to handling these types of signals is to dig for
only those targets that generate a strong, repeatable signal. As you
sweep the search coil back and forth over the ground, learn to
