Circuits designed according to the principles of low frequency or multi frequency radar despite the settings of the VDI number in the Edit and Threshold of the Surface and Size which is used in the frequency metal detector or the frequency detector have this ability according to the conditions of the reflection of the fields according to the settings of the VDI number In edit and Threshold the surface and Size which is specific for the separation of holes and wells and channels and damaged areas can be distinguished

Detecting the pressure of combined fields is one of the basic principles of how the designed circuits work according to the frequency which provides the conditions of separation and discrimination in the frequency metal detector or the frequency detector according to the VDI number in the Edit and Threshold of the surface and Size in the reflection of the fields and from there that all metals and gold and silver and resources minerals and stones and changes in the earth’s layers will reflect the field the frequency metal detector or frequency detector performs separation and discrimination according to the order set in the settings and this ability in the metal detector and frequency detector It is designed according to the radar circuits which can separate and discriminate holes and wells and canals by specifying special settings

As a result frequency metal detector or a frequency detector of any type has the ability to determine and detect holes and wells and channels and paths and types of metals and gold and silver separately according to the settings
