The Fisher FX-3 Ferro Probe senses fluctuations in the earth's magnetic field caused by buried survey markers, pipes, well casings, valves, iron relics, septic tanks and other ferromagnetic (iron or steel) objects. Because it's a differential-induction magnetometer, the FX-3 locates buried iron objects far beyond the reach of ordinary (search-coil-type) metal detectors. Like other Fisher detectors, the FX-3 is easy to operate-just turn it on and go. It weighs just 2 1/2 lbs. (1. 14 kg) and features motion detection (the tube probe must be moving to detect a target). When the FX-3's two sensors come across a large, ferrous object, the FX-3 signal tone increases in pitch and volume. When the FX-3 probe is directly over the target, the signal becomes silent and picks up again when moved past the target. The FX-3 is extremely sensitive to iron with a large surface area, highly magnetized objects and long objects buried vertically. Large or small, if it's ferrous, the FX-3 is designed to find it. In addition to its industrial uses, the FX-3 can be used by archeologists and treasure hunters to find iron relics and other buried ferrous artifacts.
