Sound an irregular tone, or the
target identification cursor
chatters
1.Don't use it indoors, because
there are many metals there.
2.Make sure whether there is
electromagnetic interference
source, such as power lines,
cables, electronic fences,etc.
Keep away from these areas or
try to reduce sensitivity.
The signal is unstable, and the
position of the target Identifi-
cation cursor is changing.
1.Sweep at a different angle to
determine whether you can get a
more stable signal.
2.If the target is buried deeply, you
could try to increase the sensitivity
or speed up the speed of sweeping
the search coil to get a more stable
signal.
3.Maybe more than one metal targets
buried there, try to increase the sensitivity
or set different discrimination ranges
to sweep.
4.Maybe you find a severe oxidation
target, or the ground is seriously
magnetic, you should try to decrease
the sensitivity.
Using PINPOINT, when the search
coil approach the ground, the unit
will sound a tone.
1.The ground is seriously magnetic
in the position near the ground,
starting the PINPOINT mode to
reduce the sensitivity.
2.There is large metal under the
ground.
