DEPTH AND TARGET DISPLAY
(continued)
ZINC:
Medium conductivity objects and many non-U.S. coins of recent vintage
are classified here.
Caution:
The target indications are visual references. Many other types of
metal can fall under any one of these categories. While the detector will
eliminate or indicate the presence of most common trash items, it is impossible
to accurately classify ALL buried objects.
DEPTH INDICATOR:
The Depth Indicator is calibrated for coin-sized objects. It indicates the
probable depth of the target, in inches.
While holding
and passing over a metal object, “DEPTH” will appear
under to the two-digit number in the middle of the screen.
TARGET-ID INDICATORS (TID)
In Discrimination Mode the three-digit target indicator, in the middle of the LCD
display, provides a specific target value to help identify buried targets. When
in All Metal Mode, it is a two-digit number. With practice you will learn to
associate target values with the probable identification of buried objects. The
target value can vary each time the coil passes over the target, depending
upon the angle of the object and the distance from the coil. For reference, see
the chart on the next page for some common Target-ID numbers.
Note Discrimination and All
Metal TID systems are
separated. You can
double-check Target-IDs
by using the quick switch
feature.
Multiple Target Category
System.
This feature is
available
only
in
Discrimination Mode. For each target, the Omega 8500 calculates four
independent numerical Target-ID’s on each pass of the coil; one primary
and three secondary. Each one of the Target-ID’s will correlate to a target
category on the LCD. There will be one solid primary category lighting up
and up to three additional secondary target categories. All are different
readings of the same target, with the primary category being the one with
most reliable signal. If the Target-ID’s vary, they will show up as multiple
illuminated categories, and this could indicate the detector is picking up
noise, a faint/weak signal or that the target is irregularly shaped.
