DEPTH AND TARGET DISPLAY
DIME:
Dimes and pre-1982 pennies will
register here. Older, pre-1982, pennies are
composed of copper, which has a metallic
signature similar to a dime. Most copper
coins will register here. Steel washers, with an
outside diameter similar to a dime, may
also register here.
QTR:
Quarters, Sacagawea and “Susan B.
Anthony Dollars” register here.
+
:
Half-Dollar coins and Silver Dollars
register here. Very large iron objects like
Sewer Lids will also register here.
Caution:
The target indications are
visual references. Many other types of
metal can fall under any one of these
categories. While the F2 will eliminate or
indicate the presence of most common
trash items, it is impossible to accurately
classify ALL buried objects.
DEPTH INDICATOR: (in Pinpoint Mode)
The Depth Indicator is calibrated to 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
while an object is in the field of detection.
the depth indicates the distance, in inches
from the center of the searchcoil to the
target.
2 DIGIT TARGET INDICATOR
The 2-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 lists some common approximate target value equivalents. With
experience in the field, you will recognize many types of metals by their numeric value.
