Depends on the size of the target, metal type and size of the search coil.


Come on man he gave you the answer "Depends on the size of the target, metal type and size of the search coil" You need to do a little of the work yourself and answer some of your own questions

Yeh thanks I figured that out but you should correct it on your schematics and re-post as corrected schematic. What worries me is if you made such a simple mistake is what ells is in store for me? Did you build from your own schematic? no I don't think so or you would have seen the missing ground on the 555 my advice to you is build before you post.

All the best and I do hope that you will verify your schematic.

Thank Ram I will have a good look at that. Do you know if it can be used with a small coil of about 200mm?
