[Funfinder]

Perfect for beginners or persons in need - very few parts!

A little ferrite-core with 100 windings but also
some larger coil will work if it has 100 microHenry.

This is because there are so many Fata Morgana's in Egypt!

Keep relaxed and I hope there is now a circuit you can built and then you have a real working metal detector!
