Notes
The detector responds with a strong signal on the meter when it detects most valuable metal
objects. If a signal does not repeat after you sweep the search coil over the target a few times,
the target is probably junk metal.
False signals can be caused by trashy ground, electrical interference, or large irregular pieces of
junk metal. False signals are usually broken or non-repeatable. Try finding other metal in the
area. When you find a metal item, wait a few seconds, to allow the detector time to reset (or,
press the RED button on the handle to return the pointer to the center of the view meter).

Fine-tuning the detector
Adjusting discrimination
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 detectors’ 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 from minimum (fully counterclockwise), to maximum (fully clockwise),
or anywhere in between. As you set DISCRIMINATION to higher levels, the detector first
discriminates iron, then metal objects like pull tabs and nickel.
When you set DISCRIMINATION fully clockwise, silver still cannot be discriminated. The sound will be
lower or even disappear and the pointer will move to left when the unit detects discriminated metal.
The sound will be higher and the pointer will move to right when the unit detects metal which is not
discriminated.
Notes
:
Each time you use the detector in a different area, you must adjust DISCRIMINATION. Each search
location presents new challenges.
Each time after you adjust DISCRIMINATION, you have to press the RED button on the handle to
return the meter pointer to 0 position..
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 recognize the difference between signals that occur at random and signals
that are stable and repeatable.
To reduce false signals when searching very trashy ground, scan only a small area at a time using
slow, short overlapping sweeps.
