Fisher's FX-3 Ferro Probe is a Differential Induction Magnetometer designed to locate iron and steel relics, property markers, pipes and other large ferrous objects buried beyond the reach of ordinary metal detectors. Two sensors respond only to the magnetic field of ferromagnetic objects, ignoring all other materials (copper, aluminum, brass, etc.). As a target is approached, the VCO (Voltage Controlled Oscillator) circuitry responds with an increase in pitch and volume then nulls directly over the target. The FX-3 is extremely sensitive to objects with large surface areas, highly magnetized objects and long objects buried vertically.
Fisher Research Laboratory has been producing rugged, high quality metal detectors longer than any company in the world. This precision instrument is a product of that proud heritage.
FEATURES
- Detects ferromagnetic objects only (iron and steel), ignores all other metals.
- Finds smaller targets than a detector yet more depth on large targets than ordinary search coil type detectors.
- Slow-Motion circuitry with VCO audio output.
- Built-in speaker. Optional head phones.
- Long battery life on a single 9 volt transistor battery. Automatic battery check.
- Waterproof probe.
- Simple one knob operation.
- Limited Warranty.

NOTES
1 . Subject to modification or improvement without notice.
2. Approximate
3. The FX-3 is a "motion" detector, meaning that the probe tip must be moving at least slightly, to detect a target.
4. Limited Warranty: Two year transferable
5. Approximate depth data for ferromagnetic objects only. Actual depth will be determined by such factors as degree of magnetization of object, size of object and orientation of object.
