DEPTH AND TARGET DISPLAY

(motion modes only)

THREE DIGIT TARGET INDICATOR

The three digit target indicator, in the
middle of the LCD display, provides a
specific target value to help identify buried
targets more accurately. With practice in
the field, you will learn to associate target
values with the probable identification of

buried objects. The target value can vary
each time the coil passes over the target,
depending upon the angle of the object
and the distance from the coil. As a
starting point, refer to the table below.

TARGET Readout

The table below list some common approximate target value
equivalents. With experience in the filed, you will recognize
many types of metals by their numeric value.

ALL METAL MODE (Default Operation)

The detector defaults to ALL METAL mode after powering on. In this
mode, all types of metals will be detected. An object’s PROBABLE
identification is indicated by the arrows at the top of the display. In
addition, the PROBABLE depth of coin-sized objects is indicated by
the rectangular segment indicators on the left side of the display. All
detected objects will cause the depth indicator to illuminate. The
depth indication is not accurate for larger objects; however, it will
provide accurate relative depth indications. The greater the distance
an object is from the search coil, the greater its depth value.

DISC/ A-M Touch Pad

Pressing this touch pad will cause the
detector to toggle between two
operating modes, DISCRIMINATION
and ALL-METAL. If the detector is in the
ALL-METAL mode (the default mode),
pressing the touch pad will change the
detector into DISCRIMINATION mode.
If the detector is in the
DISCRIMINATION mode, pressing the
touch pad will change the detector into
ALL-METAL mode.

DISCRIMINATION MODE

Discrimination is used to eliminate unwanted objects from detection.
To enter this mode, from ALL-METAL mode, press the DISC/A-M touch pad.
After pressing DISC/A-M, the detector will:

• Beep twice
• Display 3 "R"s under the left-most segments, Iron 1, 2 & 3

Ferrous objects will not be detected in DISCRIMINATION mode.

Heavily oxidized ferrous objects will sometimes, however, be
detected, usually with a high tone and an indication to the right
of the target identification scale.

To increase the level of discrimination, press the DISCRIMINATION ▲
touch pad. Each time the ▲ pad is depressed, an additional "R" will
appear, thus eliminating from detection the objects which fall into the
corresponding categories.

To decrease the level of discrimination, press the DISCRIMINATION ▼
touch pad. Each time the ▼ pad is depressed, an illuminated "R" will
