You can set the
DISCRIMINATION
control to minimum (fully anticlockwise), to
maximum (fully clockwise), or anywhere in between. As you set the
DISCRIMINATION
control to higher levels, the detector first does not detect small
pieces of aluminium foil, 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 the
DISCRIMINATION
. Each search location presents new challenges.
FALSE SIGNALS
Because your detector is extremely sensitive, signals caused by buried rubbish,
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 where there is a lot of buried rubbish,
scan only a small area at a time using slow, short overlapping sweeps.
DETECTION HINTS
No detector is 100% 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.
PINPOINTING A TARGET
Accurately pinpointing a target makes digging it up easier.
Accurate pinpointing takes practice, and we suggest you practise finding and
digging up small metal objects on your own property before you search other
locations.
Follow these steps to pinpoint a target.
•
Sometimes, targets are difficult to locate accurately due to the sweep
direction. Try changing your sweep direction to pinpoint a target.
•
When the detector detects a buried target, continue sweeping the search coil
over the target in a narrowing side-to-side motion. Make a visual note of the
exact spot on the ground where the detector beeps.
•
Stop the search coil directly over this spot on the ground. Then move the
search coil straight forward away from you and straight back toward you a
couple of times. Make a visual note of the exact spot on the ground where
the detector beeps.
•
Repeat Steps 1-2 at a right angle to the original search line, making an “
×
”
pattern.
•
The target should be directly below the “
×
” at the point of the loudest
response.
