Fisher FX-3 Ferromagnetic Locator

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.
