The CUSTOM Mode can be used to find
specific metal items. For example, if an
earring has been lost, scan the matching
earring with the ACE 250 while in the
CUSTOM mode. Note where the Target ID
cursor appears when the earring is scanned.
Next, use the DISCRIM pushbutton to move
the Target ID cursor to the left and right. Push
the ELIM button to delete the LCD cursors on
the notch Discrimination Scale, leaving only
the one where the Target ID cursor illuminated
when the earring was scanned. The ACE 250
is now programmed to find only the missing
earring based on the conductivity of its
matching pair.
ELIM can also be used to modify the Notch
Discrimination Scale to reject a specific type of
trash while detecting all other metal. When a
trash metal is detected while hunting, simply
push the ELIM button to create a notch where

the Target ID cursor signaled the presence of
the trash. The next time the ACE 250
encounters the same trash item, it will not
produce an audible signal.
• RELICS Mode - Designed to eliminate trash
targets normally associated with relic hunting,
while detecting good targets in the lower
conductivity range, such as lead and brass.
