Homemade Metal Detector

This metal detector use the VLF technology (Very Low Frequency, in this case 4.7kHz).

The documentation is free, but it is available only in Hungarian.

Hi, I also made one years ago and I know how difficult it is to get the excellent performance you have with your detector, congrats. Did you also tried pulse induction technology?

@Johndoea1 Thank you. No I didn't tried and unfortunatelly I will not try. In my country we need license for using on the field these equipments and also must be certificated. So we can't obtain a license for a homebuilt detector. This detector was tested only once in my room.

Azért a gyürűt levehetted volna...kicsit meghamisítja az eredményt,nem? :)

@Jazso13 Igazad van. Az első teszt után levettem :)

Hi, how much kost the detektor?

[soyjorgegomez]

Thanks. But the metal detector project is not included in your project page.

There are 12 projects but none of them are for metal detector. What i´m looking for is the bill of materials and some description of the coils used. I already downloaded the pcb and sch from the description. Sorry i cannot read hungarian and the translation of the .doc is useless. Regards
