OPERATION and CONTROLS (c
MODE SELECTIONS
There are three selections under the MODE section of the display.
• Press
to toggle between DISCRIMINATION and ALL METAL.
• Press
at any time to activate PINPOINT Mode.
1. DISCRIMINATION Mode
This mode is the default mode, and requires the searchcoil to be in motion in
order to detect and identify targets. This is the mode most commonly used for
continuous searching. In this mode, targets are identified with distinct tones,
and are classified in categories at the bottom of the display. A two-digit
numerical value, on a scale of 10 to 99, is displayed in the middle of the
screen. The depth range of the target is also displayed at the right of the
display. All MENU items can be selected and customized in this mode.
2. ALL METAL Mode
This mode is a motion mode. Target Identification is the same as in
Discrimination Mode but target rejection is not possible.
All types of metal objects induce a sound which varies in pitch and volume
according to the size of the object and its distance from the coil. For example,
a larger object close to the coil will induce a loud, high-pitched tone. A small
object, farther from the coil will induce a lower-pitch lower-volume tone.
Use ALL METAL Mode for maximum sensitivity to buried targets.
