DEPTH AND TARGET DISPLAY
(motion modes only)
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. 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.
THREE DIGIT TARGET INDICATOR
The three digit target indicator, in the
middle of the LCD display, provides a
specific target value to help identify buried
targets more accurately. With practice in
the field, 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. As a
starting point, refer to the table below.
TARGET Readout
The table below list some common approximate target value
equivalents. With experience in the filed, you will recognize
many types of metals by their numeric value.
