Iron Masking - Garrett ACE 400i Owner's Manual

Example: Manual Modification of Notch Discrimination Pattern
Use the NOTCH DISC buttons to position the Target ID Cursor above the pixel
you wish to eliminate (see above illustration). Use the ELIM button to delete
this pixel from the Lower Scale (see below). This item is now rejected.
Note: Changes made to the Notch Discrimination pattern
while in CUSTOM Mode will be retained when the detector is
switched OFF. Changes made to all other modes will return to
the factory settings when the detector is switched OFF and
back ON.
12 Garrett Metal Detectors
To prevent an iron object from "masking" out the signal
of an adjacent good target, use just enough discrimination
to barely reject the iron trash (e.g. small nail, as seen in
Illustration 1). This will allow you to detect the coin and
nail together (see Illustration 2) and not miss/mask a good
target.
