• COINS Mode
Designed to find most types of coins, jewelry, etc.,
while eliminating trash items such as iron and foil.
High-Res Iron Discrimination level has been preset
to 35 to exclude most iron targets. In addition,
one pixel of foil has been excluded. Be aware that
most pulltabs and pieces of tabs have not be
eliminated from detection as these trash items have
conductivities similar to small coins and jewelry.
• CUSTOM Mode
This mode can be customized by the operator and
the AT Pro will retain the changes when the detector
is switched off. The factory preset for the CUSTOM
Mode is the same as the ZERO Mode (see previous
page). Begin with this discrimination pattern and
then use IRON DISC and NOTCH DISC pushbuttons
to customize the discrimination settings.
Note: Changes made to the ZERO or COINS modes
will not be retained after the detector is switched
off.
(For information on the use of IroN DISC and NoTCH
DISC, see pages 22–26.)
