This is a new and unique system, having sound and LED indicators, for distant detection of objects buried long time ago.
All metals specified above form static electric field around themselves that can be detected from the ground. Detection distance varies according to size, conductivity, depth and period of stay underground. Metals with high conductivity, such as gold and silver, are detected more easily since they form larger electric field and the device can locate them from a distance.
The maximum tested depth of detection is 6 meters and the distance when a signal is audible – about 15-20 meters before the point of the buried object, but, theoretically, it could be more, depending on the factors described above.
The earth is constantly being bombarded by powerful radio frequencies transmitted by the military, satellites, radio, and lightning. These broadcasts induce electric currents in underground conductive bodies. Induced currents produce secondary electromagnetic fields, which can be detected at the surface, through amplified deviations of the normal very low frequency field.
The electrons from an electromagnetic field also travel in a detectable wave front from a distance. The highest reading over a target visibly stands out from neutral ground. The depth of the object can be determined along the reading line (the width of the electric field).
