There is a metal detector system that separates and discriminates only gold

There is this type of technology that the metal detector only separates and discriminates gold but it should be kept in mind that there are metals  and resources and minerals and stones and minerals and carbon and calcium which has the surface angle of reflection of the pseudo field of Gold as a result There is no Error in identifying homogeneous or co located sources and metals and minerals And the advanced metal detector has settings that by changing the settings of the operator or the user can detect the pseudo-gold field and prevent errors, or basically the advanced metal detector has settings for the separation and discrimination of other metals and interfering fields to separate and discriminate gold in depth. It provides reliability for the operator or user
