When a target is detected, the rectangular segments representing the target
category are illuminated.
Here is an example of one possible discrimination setting:
DISC = 20
V-BREAK = 50
NOTCH not set
This discrimination interface for the F19™ was designed especially for relic-
hunting.
Relic hunters want control over what sizes of iron are detected, and also control
over which targets are detected with a low-tone. Target values of 39 or less are
ferrous.
OPERATING IN DISCRIMINATION MODE
Suggestion: Try changing the
settings, watch the screen, and
pass objects over the searchcoil at
each setting. It will quickly become
obvious how these controls work.

V-Break (Change audio for certain targets)
V-Break is a feature that allows the user to change the audio response of
certain targets. V-Break allows the user to program the detector so that any
target with an ID in the range of 0 - 80 can induce a LOW tone.
Examples
:
The user sets V-Break to a desired setting (e.g. 42).
Every target with ID less than or equal to 42 induces a low tone.
The audio response of targets with IDs greater than 42 are not changed.V-
Break can be set only for Target-IDs that have not previously been rejected
using the discrimination or notch functions.
Notch Width
As you press or when adjusting the Notch Width setting, the blank
area you see across the Conductivity Arc represents targets that will not be
detected. This blank area is the “notch-window.”
Notch Width allows you to set the size (or width) of this notch-window, which
can be used to “notch out” or “notch in” targets from detection; the
maximum width of the notch-window is 20.
Notch
After setting the width of the notch-window, it can be moved around using
NOTCH. The setting you adjust corresponds to the left-most edge of the
notch-window.
Disc
Available settings from 0-80. All targets with ID's less than or equal to the
Disc setting are eliminated from detection. For example, if Disc is set to 39,
all targets with an ID of 39 or less will not be detected. By design, the
detector does not allow highly conductive targets (like silver) to be
discriminated out.
Press to eliminate unwanted metals from detection.
Each time you press the Disc value at the bottom-right of the display will
increment by one.
Press-and-hold to increase the Discrimination level rapidly.
See the Target Identification section of the manual for a detailed description of
this function.
Sections of the arc with no indication represent metals completely eliminated
from detection.
Press to detect metals which were previously eliminated from
detection
