Comprehensive Operating Manual & Guide to Metal Detecting Metal Detector Comprehensive Operating Manual & Guide to Metal Detecting Comprehensive Operating Manual & Guide to Metal Detecting Comprehensive Operating Manual & Guide to Metal Detecting 2 43 F75 F75 The F75 is a multipurpose metal detector. Its most popular uses are coinshooting and relic hunting, and it is also well-suited to gold prospecting. How Metal Detectors Work Most hobby metal detectors use VLF Induction Balance technology. Here's how they work. The searchcoil (also called search head or loop) contains two electrical induction coils which are like antennas. One coil transmits a rapidly alternating magnetic field, illuminating the region surrounding the searchcoil. If metal is present, its electrical conductivity distorts the magnetic field. If iron metal is present, its magnetism also distorts the magnetic field, but in a different way, allowing the metal detector to distinguish between ferrous and nonferrous metals. The other coil is a receiving antenna which detects changes in the magnetic field caused by the presence of metal. Electronic circuits amplify this weak signal, analyze it to determine the changes which occur as the searchcoil sweeps over the target, and then convey the 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.
