2 2µf capacitor 2 pieces speaker 8ω 170turns of 10cm diameter coil any gauge would work circuit diagram and working.
Various minelab detectors also generate a visual display of target information.
When the metal detector detects the metal object then it generates an audible sound like a beep.
However in this circuit we are using a dedicated proximity inductive sensor to identify the ferrous objects and a buzzer to raise an alarm when detection occurs.
Popularly these type of circuit uses inductors and its inductive property to sense metal detection.
How these two concepts are used together for a metal detector circuit is explained in working section of this project.
