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 differen
tiate 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 counter clockwise),
to maximum (fully clockwise), or anywhere in between. As you set
DISCRIMINATION to higher levels, the detector may at first detect
iron objects, Aluminium, thick foil and finally metal objects like pieces
of silver paper. The pointer moves to the left and the TARGET
indicator indicates by a red light.
Metal objects set by DISCRIMINATION to be detected and the pointer
moves to the right and the TARGET indicator indicates by a green light
Note: Each time you use the detector in a different area, or
DISCRIMINATION is adjusted, you will need to re-tune the detector.
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.
Detection hints:
No detector is 100 percent accurate. Various conditions influence
metal detection. The detector’s reaction depends on a number of
things:
The angle at which the object rests in the ground
The depth of the object
The amount of iron in the object
The size of the object
