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.

The target indications are
visual references. Many other types of
metal can fall under any one of these
categories. While the F4 will eliminate
or indicate the presence of most
common trash items, it is impossible to
accurately
classify
objects.
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
While holding the PinPoint touch pad,
and passing over a metal object
"depth" will appear next to the one-digit
or two-digit number in the middle of the
screen.
TWO DIGIT TARGET INDICATOR
The Two-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.
