information to the user in the form of a visual display or audio tones. Most modern metal
detectors perform many of these tasks in software running on an internal microcomputer.
The iron minerals which are present in most soils also distort the magnetic field, obscuring the
weak signals of small or deep objects. This can cause the object to go undetected, or to be
misidentified when it is detected. Much of the technology that goes into modern metal
detectors is devoted to the task of eliminating the unwanted signals from iron minerals in the
soil, while not losing the signals from metal objects.
This device has been designed to operate with the antennas listed below, and having a
maximum gain of 3 dB. Antennas not included in this list or having a gain greater than 3 dB
are strictly prohibited for use with this device. The required antenna impedance is 53 ohms.
10COIL-F70, 11COIL-F75, 5COIL-F75, 6COIL-E
The following statement is not relevant to metal detectors but is printed here to satisfy
legal notification requirement:
“To reduce potential radio interference to other users, the antenna type and its gain should be
so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that
permitted for successful communication.”
