Simplest VLF

[karamazov]

Hello

What is the simplest VLF detector that can discriminate between ferrous and non-ferrous targets?
I want to built something on my own. Thats why I need the simplest one.
If you got any schematics, links, information- I will be greatful for your help.

Thanks

This answers your question, as it's probably one of the simplest VLF detectors around. Obviously this means that it's not one of the best. You could try building this one first, and then maybe move on to the TGSL (see the Projects section of the forum).

Thank you very much.
I'll try to make it.
And I'll let you know.
