BUTTONS
OFF / ON / GAIN
Turn the knob to the right to start / turn to the left to turn it off
Turning the knob clockwise will increase the sensitivity of the detector, the
higher the sensitivity, the greater the chance of finding a smaller object or
an object that is deeper. However, with higher sensitivity, there is a greater
chance of signal interference by the electromagnetic field
Turning the knob increases the GAIN value on the bottom right of the
display
DISC sensitivity: the left knob is labeled GAIN and controls the sensitivity in
DISCRIMINATION mode
GAIN in ALL METAL mode: In ALL METAL mode, GAIN is increased by
turning clockwise
THRESHOLD is controlled independently by the right knob
DISC / ALL METAL /
THRESHOLD
Use the left DISC knob to enter DISCRIMINATION mode
Use the right button to enter ALL METAL mode
In ALL METAL mode, turn the knob to increase the THRESHOLD value
from -40 to 40
In ALL METAL mode, TRESHOLD can be set in two directions
GAIN vs THRESHOLD
GAIN
– controls the signal strength, increase the signal to detect deeper objects or small objects
THRESHOLD
– controls the audio signaling of the detector, positive values increase the volume of the
audio signal for worst detected objects, negative values decrease the volume of audio signals
For searching for objects with maximum sensitivity
: First, reduce the GAIN value to a low value.
Then set THRESHOLD to a positive value with comfortable audio signal volume. Then slowly increase
the GAIN value to the limit where you will not be disturbed by a constant audio signal.
To search for objects in silent mode
: Set the THRESHOLD value to negative values and, if
necessary, decrease the GAIN. Searching in silent mode is likely to reduce sensitivity.
