Schematic DIY KitMetal detectors To detect lines or treasure hunt
Metal detectors are a fascinating hobby. One can with some luck, find very interesting artifacts from the past or improve on the beach with his cash coins. BFO, pulse induction, VFL, there are different technologies. Here some interesting links and building instructions.

Here you will find Schematic Circuit Diagram for DIY and further information on Metal detectors
