b. Fine-tuning the Detector
When you become familiar with how your detector works, 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 the
distinction between different types of ferrous and non-ferrous metals.
You can set DISCRIMINATION to minimum (fully anticlockwise), to
maximum (fully clockwise), or anywhere in between. As you set
DISCRIMINATION to higher levels, the detector first does not detect
small pieces of silver paper, then thick foil, and finally metal objects like pull tabs from aluminium cans.
Note: Each time you use the detector in a different area, you must adjust DISCRIMINATION. Each search location
presents new challenges.
c. 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 emit 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 very trashy ground, only scan a small area at a time using slow, short
overlapping sweeps.
d. 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.

5. Operation

Your Velleman metal detector distinguishes between ferrous and non-ferrous metals. Ferrous metals contain iron,
while non-ferrous metals such as gold, silver, copper, platinum, aluminium, lead and zinc do not.
a. Preparing the Detector
Turning on the Detector
Rotate VOLUME away from OFF to the desired sound level. Set
OPERATE/BATT TEST to OPERATE to detect.
Tuning the Detector
TUNE fine-tunes the balance between the detector's receiver and transmitter circuitry to provide consistent pointer
and tone indications.
