BATTERY INDICATOR:
The LOW BATT indicator will flash as
the unit is powered on. If the
indicator comes on and stays on,
replace the batteries.
DEPTH INDICATOR:
The Depth Indicator is accurate for
coin-sized objects. It indicates the
depth of the target, in inches. Large
and irregularly-shaped objects will
yield less reliable depth readings
When passing over an object, the
depth indicator will light up and stay
illuminated until another object is
scanned. Pass repeatedly over the
suspected target and pause briefly at
the end of each sweep to read your
display. Repeated indication at the
same depth level indicates an accurate
target detector. If the depth indication
varies with each sweep, try sweeping
at different angles; there may be more
than one target present. With practice,
you will learn the difference between
accurate readings, multiple targets,
and highly erratic readings which
evidence trash or irregularly shaped
objects.
SENSITIVITY ADJUSTMENT:
The principle use for the SENSITIVITY
knob is to eliminate
ELECTROMAGNETIC INTERFERENCE
(EMI). EMI is both naturally-occurring
and man-made. Common sources of
EMI are power lines, both suspended
and buried, and broadcasting
antennas. Machinery, when in
operation, can also produce EMI.
EMI comes from most household
appliances, so
YOUR DETECTOR
CAN BEHAVE VERY ERRATICALLY
INDOORS.
If you want to test it
indoors, turn off the TV and
microwave. If you have lights with
dimmer switches, also turn these off;
dimmer switches can produce lots of
EMI.
If your detector falses with the
SENSITIVITY knob in the 100%
clockwise position, reduce the
sensitivity until the chatter stops
(usually to the 1:00 or 3:00 position).
If you suspect the presence of deeper
targets underneath a shallower target,
reduce the SENSITIVITY to eliminate
the detection of the deeper target to
properly locate and identify the
shallower target.
