AT Pro International™ 15
PRO DETECTION MODES
Zero, Coins or Custom have the same discrimination
patterns as in STD Mode. In PRO Mode, however, the
AT Pro
utilizes its Pro Audio functions—including Proportional Audio
and Tone Roll Audio—to offer more target information.
The Pro Mode audio provides more target information and
faster recovery speed for separating adjacent targets. This
is especially important in areas where good targets may be
scattered amongst iron trash.
Pro Mode audio by its nature creates more audible chatter
than Standard Mode. This is normal because of the additional
sensitivity of Pro Mode. The audio depth can exceed Target ID
depth in Pro Mode so it is possible to hear deep targets that
do not register a Target ID.
Proportional Audio (Pro Mode)
Proportional audio response means that the loudness
of the target's response is proportional to a target's signal
strength. This allows the user to hear subtle changes in a
target’s response. Proportional audio response also allows
the user to better judge a target’s size, shape and depth
and has the additional benefit of faster recovery time for
separating adjacent targets.
