The search coil works as sensing probe and must be moved over the ground to detect potential metal targets buried underground. When the search coil detects metal objects, the device gives an audible signal via speaker or earphone. In most units, the feedback is an analog or digital indicator.
A variety of technologies are used to detect landmines, improvised explosive devices (IED) and unexploded ordnance (UXO), including acoustic sensors, animals and biologically-based detection systems (bees, dogs, pigs, rats), chemical sensors, electromagnetic sensors and hyperspectral sensor analysis, generalized radar techniques, ground ...

Another source estimates that a 100 m long and 10 m wide submarine would produce a magnetic flux of 13.33 nT at 500 m, 1.65 nT at 1 km and 0.01 nT at 5 km. [6] To reduce interference from electrical equipment or metal in the fuselage of the aircraft, the MAD sensor is placed at the end of a boom or on a towed aerodynamic device. [7]
A dowser, from an 18th-century French book about superstitions. Dowsing is a type of divination employed in attempts to locate ground water, buried metals or ores, gemstones, oil, claimed radiations (radiesthesia), [1] gravesites, [2] malign "earth vibrations" [3] and many other objects and materials without the use of a scientific apparatus.

A MEMS magnetic field sensor is a small-scale microelectromechanical systems (MEMS) device for detecting and measuring magnetic fields (magnetometer). Many of these operate by detecting effects of the Lorentz force: a change in voltage or resonant frequency may be measured electronically, or a mechanical displacement may be measured optically ...
