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.
MODE INDICATOR:
Choose from one of the four operating
modes by pressing the touch pad. An
arrow will indicate the current
operating mode. Change to any mode
at any time by pressing the
corresponding touchpad
Note: The Retune touchpad is
used only to ground balance the
detector when operating in the
ALL METAL Mode.
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 chatters 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.

INDICATORS & SENSITIVITY ADJUSTMENT
DISCRIMINATION Mode - continued
• Turn the right knob, DISCRIMINATION,
to eliminate additional unwanted
items from detection as illustrated to
the right. These positions are
approximate; objects are found in
many shapes and sizes.
The detector will emit one of three
tones, depending on the type of metal
detected.
The top display will indicate the
type of metal targeted.
A valuable target is indicated by a
consistent tone and a repeatable
target indication as you sweep back
and forth over the same spot on the ground. Non-repeating tones usually
indicate the presence of trash objects or highly oxidized metals.
You can increase the level of sensitivity, depending on the ground
conditions. If the detector emits false signals, simply reduce the Sensitivity
until the false signals cease. The detector will work well with the Sensitivity
in the 2:00 or 3:00 position, but higher Sensitivity settings will increase depth
detection. If you need maximum depth detection, operate in the ALL METAL
Mode, which allows for higher Sensitivity control settings.
Note that gold is unfortunately discriminated out with common trash
items. Gold’s metallic signature covers a broad portion of the metallic
spectrum. If searching for gold jewelry in trashy areas, use AUTO NOTCH
and be prepared to dig up some trash items in your search for gold.
NOTCH Mode
To operate in this mode:
• Press the NOTCH touchpad.
• Use the Discrimination Knob to eliminate medium tone trash items
from detection, but still retain low and high tone valuables.
AUTONOTCH Mode
To operate in this mode:
• Press the AUTO NOTCH touchpad.
• Most pull-tabs and medium tone trash items are automatically
eliminated.
• The Discrimination Knob operates as in the NOTCH Mode.
To change into any mode at any time, simply press the desired button.
The Retune button only functions when in the ALL METAL Mode.

USING HEADPHONES
Using headphones (not supplied) improves battery life, and prevents the
sounds from annoying bystanders.
It also allows you to hear subtle changes in the sound more clearly,
particularly if searching in a noisy location. For safety reasons, do not use
headphones near traffic or where other dangers are present. This device is
to be used with interconnecting cables/headphone cables shorter than three
meters
