Finder or detector or metal detector or hand-held ground radar or mine detector in the frequency type, considering that it operates with the frequency current belonging to the frequency radar and the low frequency emission with the electromagnetic field with a positive electric charge and has a VDE number in the edit and threshold level. And the volume is the circuit, according to the conditions of the settings, it can remove or remove the state of these magnetic fields or magnetic density or the fields of error-causing factors from other sources in the reflection, or it can detect these error-causing points, and this power of the frequency finder circuits It is based on the settings and resolution
