on either side. The AT Pro is now programmed to find the
missing earring based on the conductivity of its matching
pair.
Note: The notch discrimination function can be used
to modify each Mode's discrimination pattern. Notch
Discrimination modifications made while in CUSTOM (either
in Standard or Pro mode) will be retained when the detector
is switched OFF. However, all changes made to the Notch
Discrimination pattern while in ZERO or COINS modes will
return to the factory settings when the detector is switched
OFF and back ON again.
Iron Discrimination—The AT Pro features a high-resolution
iron discrimination adjustment. This additional resolution
allows more precise control of how much iron discrimination
can be applied. The level can be adjusted from 0 (no iron
discrimination) to 39 (maximum iron discrimination).
