I think that you buy a metal detector attach the box any where in you want.Then attach a longer cable from the box to your gate or whatever. Next you make a custom coil that fits on the inside of the gat[the coils is just a bunch of copper wire] Then when someone walks through the gate you can check the detector or listen to it.
