TARGET IDENTIFICATION
In DISCRIMINATION Mode, targets
are identified both audibly and visually
as follows:
1. Different pitch tones for different types
of metals
2. A 2-digit Target-ID
3. An illuminated icon within the target
category best describing it.
UDIO T RGET IDENTIFIC TION:
LOW TONE (ID: 1 - 39)
Tones identify targets as follows:
Ferrous objects, such as iron and steel,
like nails and tin cans. Smallest-sized gold
MEDIUM TONE (ID: 40 - 79)
objects and some steel bottle caps
Foil, pull-tabs (some new style), nickels,
steel bottle caps. Newer pennies (post-
1982 are minted from zinc). Larger gold
pieces, small brass objects, and most bottle
screw caps. Most recent-vintage non-US
HIGH TONE (ID: 80 - 99)
coins. Pull-tabs (old style, some new style)
Silver and copper coins, large brass
objects. Older pennies (pre-1982 were
minted from copper). Dimes, quarters,
half-dollars, silver dollars. Susan B.
Anthony and Sacagawea dollar coins.
Flattened aluminum cans (with a stronger

The 2-digit value in the middle of the
screen provides a specific target value to

identify
accurately. With practice in the field, you
will learn to associate target values with
specific objects. Coins are more likely to

(Post-1982), Many screw caps
yield the same value with each pass of the
coil due to their concentric shape. The
presence of multiple targets will yield
multiple tones. Trash objects are more
likely to yield a different number on each

searchcoil for practice, wave with the flat
side parallel to the searchcoil; this is the
position you will most often find coins
buried in the ground.
