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 the sound will be lower or even
disappear and the pointer will move to left when the unit detects discriminated
metal. Non discriminated metal will cause the sound to be higher and the
pointer will move to the right.
NOTE:
• Each time you use the detector in a different area, you must adjust the
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, areas with high metal content 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 recognise the difference between signals that occur at random
and signals that are stable and repeatable. To reduce false signals when
searching scan only a small area at a time using slow, short overlapping sweeps.
