Question help with a project

speedy Pete, please could you help me in my university project? I am doing a product design course and have to re-design a voltage/metal detector but i cant find any research anywhere! any information or useful sites that explain how they work and who uses them and where, or even your opinion on products you have used would be extremly helpful!
cheers welshlad!

Eriez Metal-Detectors;



The best way to locate a product is the Thomas Register.

Good Luck!!!

I have several tester like you describe, from stud finders which can detect metal and electricity to high $$ circuit tracers. Only I cannot find any info on how they actually work. I know they work on some electromagnetic field principle but I can't find anything specific.
Any sites I do find are only for selling these things.

I would just keep searching the web with different terms until you get what you want.
Sorry I can't be of more help.

A metal detector and a voltage/signal detector are two different devices. Both work differently. It would be helpful to narrow down the request to a specific device. What's the application??
