Target ID Legend
—
Works with the Target ID Cursor to
indicate a target's probable identity, with Ferrous (iron) targets at
the left, non-ferrous targets that are thin or have low conductivity
in the middle, and thick or high conductivity targets (e.g. thick
silver) at the right.
Lower Scale
—
Displays the current discrimination pattern,
with lighted pixels indicating accepted targets and blank pixels
indicating rejected targets.
Target ID Cursor (Upper Scale)
—
Will display for every target,
but will produce audio only for targets accepted on the Lower
Scale.
Digital Target ID
—
Provides a value from 0 to 99 to identify
targets more precisely than the ID cursor.
Coin Depth Indicator
—
The depth of a coin, or a similar sized
target, is indicated in 2-inch increments. Note: targets
larger
than
a coin may display shallower than actual depth while targets
smaller
than a coin may display deeper than actual depth.
The sample chart on the following page provides Digital Target
ID ranges of some commonly found items.
Volume Adjust
To control the maximum loudness of target sounds, press the Shift
button and then use the (+) or (-) VOL ADJUST buttons to set to
your preference.
•
Note that the
AT Max
's volume adjustments only affects
the maximum audio produced by a large signal and does not
affect the audio level or sensitivity of faint signals (i.e. Volume is
a "limiter" and not a gain control), thereby preserving maximum
detection of faint signals.
• To ensure maximum detection of faint signals when using
headphones, set the headphone's volume to maximum and
adjust the
AT Max
's volume to your preferred level.
Target ID can vary widely based upon the target's size and
thickness because small, thin pieces of metal cannot conduct
electrical current as well as thicker pieces of metal. In addition,
mineralized soils can cause Target ID errors, especially for small
targets.
Tip: Target ID is most reliable when the target is centered under
the searchcoil and the coil is swept flat and at a constant height
above the ground.
