BASIC OPERATION
NOTCH Mode
To operate in this mode:
• Press the NOTCH button.
• Use the Disc/Notch Knob to eliminate medium tone trash items from
detection, but still retain low and high tone valuables.
AUTO-NOTCH Mode
To operate in this mode:
• Press the AUTO-NOTCH button.
• Most pull-tabs and medium tone trash items are automatically
eliminated.
• The Disc/Notch Knob operates as in the NOTCH Mode.
NO-MOTION ALL METAL MODE
To operate in this mode:
• Hold the searchcoil over the ground surface, about 1/2 inch.
• Press the All Metal Button.
The detector will emit only one monotone sound, regardless of the type
of metal detected.
If the detector emits a constant tone, press GROUND-TRAC
searchcoil just above the ground surface. Make sure that the ground area
chosen for tuning the detector does not contain metal; if unsure, switch into
DISC Mode, turn off DISCRIMINATION and verify that the detector does not
emit tones as you sweep the coil over the chosen spot.
Ground conditions can change over short distances. Until you become
familiar with the detector's volume level, retune the detector periodically by
pressing the GroundTrac button.
Temperature changes also require retuning, by pressing the Ground-Trac
button. If the detector emits a constant tone, or loses sensitivity, retune. If
you have stored the detector indoors and move outdoors immediately to a
different temperature environment and begin detecting, retune the detector
periodically until the coil temperature stabilizes.
necessary in the ALL METAL Mode.
To change into any mode at any time, simply press the desired button.
The GroundTrac button only functions when in the All Metal Mode.

AUDIO TARGET-ID
In the DISC, NOTCH or AUTO-NOTCH
Modes, the detector emits three
distinct tones, which classify metal
objects into categories
IRON & STEEL:
In the DISCRIMINATION Mode most
iron and steel objects will induce a low
tone. Highly oxidized iron can induce a
high
tone,
Disc/Notch
instance, some rusted bottle caps will
induce a high tone and indicate to the
right of the LCD target display. A very
large iron object, like a manhole cover,
can induce a high tone.
GOLD:
Gold objects will induce a low or
medium tone, depending on their
®
with the
sizes. Very small gold objects will
indicate on the left-most segment.
Large gold objects will read under the
Zinc segment. If you are gold
prospecting, you will usually be
looking for natural gold in an area
which it does not contain much trash,
and can therefore ignore the specific
segment descriptions.

PULL TABS:
Pull tabs are the most bothersome
trash items for detectorist. Most will
induce a medium tone. Most will be
eliminated automatically in the AUTO
NOTCH Mode, or alternatively be
manually "notched out" in NOTCH
Mode with the Disc/Notch control. The
depending

the
older pull tabs (those not attached to
control
setting.
For
the can after opening) are sometimes
broken in half; these broken tabs can
induce low tones. Highly oxidized pull
tabs can also induce high tones.
It can be very difficult to differentiate
pull tabs from gold rings. When they
both induce medium tones, you might
notice a "double beep" from a gold
ring but a "single beep" from pull tabs.
To achieve this distinction, sweep the
searchcoil very slowly, and at different
angles. Two tones might signal as the
detector passes over each side of the
round ring.
COPPER, SILVER & BRASS:
Most valuable coins are composed of
these metals and will usually induce a
high tone. Valuable objects other than
coinage can also be composed of
copper, silver and brass.
