will increase or decrease the level of discrimination. Each press
of the pads will cause a target icon to appear or disappear on the
display. When an icon is not illuminated, the corresponding target
category will be eliminated from detection. No audible tone nor target-
icon will appear when the searchcoil passes by an object in a category
which is not illuminated.The Dime, Qtr, and
+

target categories cannot
be eliminated from detection.
While searching, the only target category icons visible are those
indicating detected targets; no more than one is visible at a time
while searching. In order to display the discrimination status, press
either the DISC
or
key. The first press of either DISC
or
displays the current discrimination status (eliminated target categories
are not displayed — all accepted target
categories are illuminated).
This first key press does not change the
discrimination status; each subsequent
DISC or
will change the
discrimination setting, with icons either
disappearing or reappearing.

SENSITIVITY
AND
These controls change the detector’s sensitivity; higher settings enable
detection of deeper targets. At power-up, the detector is pre-set to 75%
of maximum sensitivity. At minimum, the sensitivity is 35% of maximum. With
each press of the
o
o
r
r
touch pads, the sensitivity level is displayed on
the bar graph on the left of the display. Upon reaching the minimum or
maximum sensitivity setting, the detector will beep twice.
While higher levels of sensitivity enable detection of deeper targets,
operation at high levels of sensitivity make the detector m

Higher
sensitivity settings can also lead to false
signals in difficult ground conditions. Use
lower sensitivity settings to suppress
interference or false signals from soil minerals
when necessary.

DEPTH AND TARGET DISPLAY
READING THE DISPLAY
The Liquid Crystal Display (LCD) shows
the PROBABLE identification of the
targeted metal, as well as the PROBABLE
depth of the target, in inches.
The target category will illuminate
where an object is best classified,
and stay illuminated until another
target is identified.
The detector will normally register a
repeating, unchanging target
identification when a buried target
has been located and identified. If,
upon repeated passes over the same
spot, the target identification reads
inconsistently, the target is probably a
trash item, oxidized metal, or too
deep to be classified accurately. With
practice, you will learn to unearth
only the more repeatable signals.
The segment identifications are highly
accurate, when detecting the objects
described on the label. However, if
you register in a given category for an
unknown buried object, you could be
detecting a metallic object other than
the object described on the label, but
with the same metallic signature. Also,
the greater the distance between the
target and the coil, the less accurate
the target identification.
