The new Metal Detector F3J is made with an aerial transmission system that is able to produce a variable magnetic field and with a reception system where the magnetic field generates induced current that is elaborated through an exchange of electric current. The antennas' special configuration generate an even field, so they can detect the objects wherever they may be within the area surrounded by the antennas.

Thanks to the modern technologies used, all of the electric components have been placed on a single card keeping the dimensions and weight down. The settings of the working parameters are obtained through a software, a special console or PC with return message, in this way it uses a modern communication request system, avoiding a direct manual maintenance on the card. The system is completely managed by a fast microprocessor that will make a complete diagnosis in real time. The special filter functions allow the F3J model to be free from interferences.

The possibility to change the parameter's entire range and the automatic search for the best frequency allows the F3J Metal Detector to be versatile and adaptable under any environmental condition.
