AUDIO TARGET ID
Depending on the operating mode
and Disc/Notch control setting, the
Pioneer 202 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, depending on the
Disc/Notch control setting. For
instance, some rusted bottle caps will
induce a high tone and indicate to the
right of the LCD target display.
GOLD:
Gold objects will induce a low or
medium tone, depending on their
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
older pull tabs (those not attached to
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
search coil 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.
