Target Identification - Teknetics Gamma 6000 Owner's Manual

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 The detector
must be in DISCRIMINATION Mode to
identify targets.
The ALL METAL Mode does not provide
target identification.
AUDIO TARGET IDENTIFICATION:
When in the 4-tone mode, tones identify
targets as follows:
BASS TONE- Ferrous objects, such as
iron and steel, like nails and tin cans.
Smallest-sized gold objects and steel
bottle caps
LOW TONE- Foil, pull-tabs (some new
style), nickels, steel bottle caps.
MEDIUM TONE- Newer pennies (post-
1982 are minted from zinc). Larger gold
pieces, small brass objects, and most bottle
screw caps. Most recent-vintage non-US
coins. Pull-tabs (old style, some new
style)
HIGH TONE- 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
signal than a coin)
2-Digit Target Identification
The 2-digit value in the middle of the
screen provides a specific target value to
help identify buried targets

accurately. With practice in the field, you
will learn to associate target values with
specific objects. Coins are more likely to
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
pass. The angle of the coil relative to an
object may also influence
identification. If waving coins over the
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.

Do not twist the Cable or Plug. Turn Locking Ring only.
Use minimal finger pressure to start the threads. Do not
cross-thread. When the Locking Ring is fully engaged over
the threaded connector, give it a firm turn to make sure that it
is very tight. When the Locking Ring is fully engaged over the
threaded connector, it may not cover all of the threads.
G
Tighten both LOCKING COLLARS.

Note: Very tall users can purchase the optional Extended Lower Stem (TUBE5X), for extended reach.
Caution:
Forcing in MIDDLE STEM with CAM LOCK raised may form a burr on
camlock. If this happens, remove burr with knife to allow insertion.
