Pushbutton
Press and release the IRON AUDIO pushbutton to switch the
Iron Audio feature ON/OFF. When this feature is on the words
"IRON AUDIO" appear on the LCD (as shown in the illustration
above). The Iron Audio feature can be used in any of the AT
Pro's six modes.
Scattered iron objects in the ground can mask good targets
and even create "ghost signals" that appear to be a good
target. Garrett's selectable Iron Audio feature allows the user
to hear discriminated iron (normally silenced) in order to
know the whole picture and avoid being tricked into digging
an undesired target.
Iron Audio also allows adjustment of the mid-tone's range
to include all targets above the iron discrimination setting.
The user is adjusting the cut-off between low-tone iron targets
and mid-tone targets to better distinguish good targets.
