Controls and Function
1. Sensitivity
Control
The sensitivity knob is used to turn the instrument power ON and
OFF and to adjust the response of the instrument.
As the knob is turned further clockwise, detection depth as well as
sensitivity to small metal items increases. Unfortunately, external
electrical interference (broadcast antennas, power lines, etc)
and ground interference also increases.
For good results in most conditions the “P”(Preset) position works
well.
2. Discrimination
Control
The Discrimination (DISC) control selects the amount of rejection
against trash metals.
As the DISC knob is turned clockwise, more and more trash
rejection is achieved. At the fully clockwise position nearly all trash
metals are rejected as well as some valuables.
The DISC knob is active only when the detecting mode toggle
(located on the handle/rod) is in the center position (DISC Mode).
