Elimination of the metal field not specified in the settings is one of the principles of frequency radar circuits for accurate separation and discrimination
Elimination of the metal field that is not specified in the VDI number settings in the Edit and Threshold of the surface and size and other settings is done in the reflection of the field of other metals in the radar circuit
The radar circuit removes any type of field from other metals that are returned to the frequency system and the desired metal field such as gold that is specified in the settings the radar circuit separates and separates and discriminates and accurately separates and discriminates the desired metal field
Set the VDI number settings in the Edit and Threshold of the surface and size on Gold only the Gold field in the return reflection is separated and discriminated or the field of any other metal that is in the search area the radar circuit removes and evaluates the gold field as the target specified in the settings and forms accurate separation and discrimination
The metal detector circuit or any type of detector or GPR or ground handy radar or mine detector or antenna metal detector is the same long range locator or Ground penetrating radar of the frequency type with the mentioned settings has the ability to accurately distinguish the target field of interest in the frequency return reflection even during testing at great depths
