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.

PINPOINTING A TARGET
1. Turn the MODE SELECTOR (6) to TR2 position to determine the quality of
the metal.
2. Continue sweeping the search coil over the target in a narrowing side-to-side
motion.
3. Memorise the exact spot on the ground where the detector beeps.
4. Stop the search coil directly over this spot on the ground. Now move the coil
slowly forward and back a couple of times, again stopping over the strongest
response.
5. Move the coil side-to-side over more time and stop over the strongest signal
once again. Your target should be directly below the “Hot Spot” of the search
coil.
OPERATION TIPS
When you are working in an unfamiliar territory, always bury a coin and check it at
different discrimination and sensitivity levels. There may be some sensitivity loss
at higher levels of discrimination. Here are some suggested tips of operation.
1. If the detector display or sounds false signals, it may be due to one of the
following reasons:
a. The sensitivity may be set too high.
b. Your sweeping speed may be too fast, or at a wrong angle.
c. The target is a heavily oxidized metal.
2. The display does not show the correct type when the detector finds a target.
The reasons may be due to
a. More than one target.
b. An alloy that the detector does not recognize.
c. The target is heavily oxidized.
d. The sensitivity may be too high.
