6. How it Works
•
A (low frequency) metal detector basically consists of a transmitter, a receiver and a microprocessor
(control box) which handles the signals.
Transmitter
•
The transmitter is a coil of wire located inside the search coil. By sending an alternating current through
this coil a magnetic field is generated, having a polarity pointing either into or out of the ground. This
magnetic field will induce a flow of current inside nearby metallic objects. These objects in turn will create a
magnetic field with a polarity, which is usually opposite to that of the magnetic field of the transmitter.
V. 03 – 09/08/2021
discrimination control: to eliminate (notch) undesired metals
Note: this setting influences the sensitivity
ground balance control: to eliminate background signals caused by mineralized
soils
volume button: set speaker or headphone volume to normal or low
trace button: to keep the detector in tune
headphone jack: to connect an external headphone (not incl.)
sensitivity control: to control the depth of detection
threshold control: adjust the level of the received signal
low battery indication: lights up when voltage drops below 8.8V
discrimination mode selector: in DISC mode, type of metal is indicated by tone
length; in TONE mode it is indicated using high or low tones
needle indicates signal intensity (ALL METAL mode) or metal type (DISC mode)
