MENU ITEMS

Discrimination allows you to eliminate metal objects from detection. It is
DISC LVL: Discrimination Level
adjustable from 0 to 80. A discrimination setting of zero is not the same as All
Metal. Discrimination incurs some loss of sensitivity to small and deep objects.
As you adjust the discrimination level, a number will appear in the center of the
LCD. All targets that report a number LOWER than the set discrimination level
will not report a sound or display activity. They have been eliminated from
detection. Note also that target category identifiers will start disappearing from
the top of the LCD screen as you increase the discrimination level. When a
target icon disappears, it means the whole category has been eliminated from
detection. Lowering the DISC LVL setting will make the target category
identifiers return to the screen, even if they are partially eliminated by the
numerical setting.
