This isone of the most popular metal detectors currently in use. This is especially soamong experienced treasure seekers. The detector can be highly accurate andsensitive. This coil also has a pair of coils, which work together. The firstcoil is the transmitter, usually giving off an intense electric current. Thesecond coil is a receiver; it picks the signal from the main coil and amplifiesit many times over.
Thetransmitter coil works by looping a magnetic field above and below ground. Thisfield usually extends about two feet into the ground. The field usually staysthat way until it comes across a metal object. When this happens, the objectdevelops a magnetic current. This current then interferes with the perfectmagnetic loop running into the ground. Thus, the secondary coil picks up theinterference. This coil magnifies and sends into an audio system attached tothe Metal Detector. Thus, the person is able to tell if there is an object inthe ground. The beauty about this detector is that each metal objectorgenerates a different frequency.
Highlymagnetic objects such as steel or iron generate a very power field. This fieldis quite distinct and some detectors have the technology to indicate this. As aresult, one does not waste endless hours digging up worthless objects. Inaddition, it can detect objects with a very low magnetic pulse. This includesprecious objects such as gold. Ultimately, this is the aim of buying a metaldetector. As a result, it would be self-defeating not to invest in such a goodmetal detector. With this type of metal detector, one has a higher chance ofdiscovering precious stuff buried underground.
