BASIC OPERATION

PROBABLE TARGET
The four categories depicted across the top of the display
indicate the probable identification of buried, detected metal
objects. The searchcoil must be in motion over an object to
be detected. Alternatively, you can pass an object over a
motion less searchcoil to test your detector. One of the four
target indicators will illuminate, indicating the probable
identification of the object. The indicator will remain
illuminated until another object is detected.
You will encounter a never-ending variety of buried metal
objects. It is therefore impossible to accurately identify all
buried metal objects. The Target-Identification system will
accurately identify the most common items.
Commonly-found object are classified into the four categories as
follows:
IRON ------------------------------------------------
Ferrous objects
Metals composed mostly or
entirely of iron
Most very small metals objects
Small foil pieces; small gold
pieces.
AL 5¢ ------------------------------------------------
Large gold rings
Newer pull-tabs (those which
stay connected to can)
Nickels
Large Aluminum Pieces
AL ZN ------------------------------------------------
Post-1982 pennies (are made of
zinc, some zinc pennies will register
as coins within 1” of the coil). -Zinc
coins, such as recent foreign
currency -Most bottle screw caps. -
Large foil pieces. -Many rings; most
gold rings. -Older pull-tabs (those
which detach from the can)
COINS ------------------------------------------------
Silver coins, like dimes and
quarters. -Copper pennies (pre-
1982). -Very large metal objects
like manhole covers.
