Is underground metal detector useful?
Many people have doubts. Is the underground gold metal detector true? Is it really useful? It can detect antiques, gold, silver, copper, iron, porcelain, silver? The answer is yes, of course it can be detected.
Gold scanner machines mainly detect and detect metal objects, and need to detect specific substances, such as gold, silver and porcelain.
To understand the underground gold finder machine are of no use, still need to understand the internal principle of its structure, underground gold scanner metal detector can detect metal because the underground metal detectors will go underground launch a ripple, meet iron, iron particle movement will change the magnetic field caused by the magnetic flux deformation, so that the electric potential change of reaction to handle underground metal detectors have a signal, thus it can be found that the underground material, so the underground metal detector is useful!
