To Carl and others

[Vladimin]

Carl I am wondered that a lot a people here are trying to find a schematic diagram of commercial metal detector and they hopes that this circuit will solve all problems just at the moment.I think that they doesn't have no one idea what is going there inside in the detector.Because if they knew that they will build detector with own circuitry.Is this true?

[Carl-NC]

I'm not so sure. I think in some cases, people want a schematic of a detector they own, in hopes of modding it for better performance. In other cases, people want a schematic in order to build a clone. Either way is a good way to learn about detector design, which is the first step before attempting your own design.

You have right.If they want to modified there's detector is good idea.I thing that sometimes is good to take a look from comercial circuitry just for some usefull idea.
