Detectors or Metal Detector or Ground Handy Radar or GPR or Mine detector or Long Range Locator that wants to reveal the status of targets or metals during training, testing and training must be able to reveal or specify the field of Gold, Silver and Metals, and the Measuring magnetism devices or Ion measuring devices such as Magnetometers or Ion Detectors do not have the circuit conditions and settings to detect and reveal the field of Gold and Silver or Diamagnetic Metals, and even Measuring magnetism devices or Ion measuring devices such as Magnetometers or Ion detectors or Tesla are not able to detect And the Detection of weak Magnetism or Ion flow is not related to Gold and Silver metal and Diamagnetic Metals, as a result, the Detection of Gold and Silver or Diamagnetic Metals requires the salty Metal to be new or old or has remained underground for many years, Magnetometer or Ion Tesla Detectors or Measuring magnetism devices or Ion power measuring devices do not detect and reveal so that these types of devices can be used as Metal Detectors in the Main work scene.
