The discrimination pattern for this mode is designed
to find all types of coins and eliminate trash items
such as iron and foil. Five pixels of ferrous targets and

iron trash, many pulltabs and pieces of tabs from

In COINS Mode, 5 pixels under ferrous and 2 pixels of non-ferrous targets are
notched out.
