Discrimination settings allow you to exclude some kind of metal. Just near to the coil some object that is made from a metal you want to exclude, and press DISCRIM Buttom.
If you're trying to seek for coins, ACE250 is very precise in my opinion for USA coins. The same I can say for brazilian coins (my case). ACE250 doesn´t help me because most of coins are bimetalic or are made for a mix of metals.
