Zisme Detector

[sharky]

Zismes New Homebrew Metal Detector on http://oldradiobuilder.com/MDET.html is a little improvement!!! Doesnt the capacitors reduce the small voltages the coil detects, Is it better to use a second coil for Rx instead of the capacitors...is it better to use single supply instead of dual supply for Opamps!!
