The basic concept used is that the presence of a metal can vary the inductance value of an inductor.
Arduino pi metal detector.
The search coil closest to the metal will light up better helping identify the location of the hidden treasure.
Would be nice as an open source project with the code to be downloaded and modified to your needs.
The amount of amplitude change and phase change is an indication for the size and distance of the metal and can also be used to discriminate between ferrous and non ferrous metals.
Metal detector is a security device which is used for detecting metals which can be harmful at various places like airports shopping malls cinemas etc.
It is easier to make than a vlf metal detector because you do not need to adjust the coils and adjust the balance of the coils.
Maybe even with a custom arduino shield.
