OBJECT IDENTIFICATION ON DISPLAY AND AUDIO SIGNAL
SIGNAL INDICATOR
The lower left bar graph shows the signal strength when the device is in DISCRIMINATION mode.
Signal strength shows the size of an object hidden in the ground or how close it is.
If all segments are displayed, the found object is large or close to the surface.
If one or two segments are displayed, the found object is small or deep below the surface.
DEPTH INDICATOR
If you are using DISCRIMINATION MODE, you can check the position and size using the PINPOINT
function. Press PINPOINT to temporarily find an object without having to move the coil.
When you press PINPOINT, the DEPTH indicator appears. The displayed value shows the depth of
the object in inches. The distance is measured from the coil to the object. The PINPOINT function is
calibrated for coin-sized items. For larger objects, the numerical value is relative to the depth.
AUDIO SIGNAL
•
If an object is detected, two types of sound signals are emitted:
•
V.C.O
•
Deep tone
In DISCRIMATION mode, objects are announced using V.C.O tones and shaded objects by deep
tones. Users can adjust the sensitivity using the + and - buttons.
In ALL METAL mode, all items are announced using V.C.O.
V.C.O tones change depending on the depth of the subject. A stronger signal emits louder and higher
tones. A weak signal emits a quiet and deeper tone. Therefore, it is advisable to use headphones to
find smaller items.
TWO DIGIT IDENTIFICATION
In DICRIMINATION mode, a two-digit identification will help you identify a hidden object. Through
practice, you will learn to better identify objects by codes. The number changes each time you find an
object, depending on its depth and size.
