AuDIO CHArACTerISTICS
The
AT Gold
's advanced audio characteristics provide
fast recovery speed, which is especially important in areas
where good targets are in close proximity or may be scattered
amongst iron trash.
(See Example A.)
Adjacent
targets
Example A:
Adjacent targets can often produce a single strong signal with
many metal detectors. The fast recovery of the
AT Gold
, however, will provide
two peaks of audio response to these adjacent nuggets. These multiple
audio responses provide the experienced user with more target information.
This fast recovery time helps the
AT Gold
operator to
separate adjacent targets. The proportional audio response
which makes this possible also allows the user to better
judge a target’s size, shape and depth. Proportional audio
response means that the loudness of the target's response
is proportional to a target's signal strength (i.e. small/deep
signals sound faint and strong/large signals sound loud).
(See
Examples B and C.)
Shallow nugget
Proportional Audio Target Examples
Example B:
Notice the different target response provided by the
AT Gold
's
proportional audio in regards to target depth. The shallow target offers a
stronger signal, while the same-sized deep object provides a softer signal.
Deep nugget
Small
nugget
Large
nugget
Example C:
Notice the different target response provided by the
AT Gold
's
proportional audio in regards to target size. The small nugget provides a
softer signal, while a large nugget at the same depth provides a strong
signal. Target size can be estimated by raising and then swinging the coil
over the target. large targets continue to be detected at greater distances
from the coil while small targets more quickly lose detection.
