Like other Fisher detectors, the FX3 is easy to operate; just turn it on and go. It weighs just 2.5lbs (1.14kg) and features motion detection (the tube probe must be moving to detect a target).
When the two sensors come across a large ferrous object, the signal tone increases in pitch and volume. When the probe is directly over the target, the signal becomes silent and picks up again when moved past the target.
The unit 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 FX3 is designed to find it.
In addition to its industrial uses, this unit can be used by archeologists and treasure hunters to find iron relics and other buried ferrous artifacts
