Steve,

You're right,a 249GHZ signal will not penetrate soil more than a few centimeters if I'm remembering right. Far as gold on the surface the transmission distance would not be great to due the curvature of the earth and at that frequency even if it is at a high elevation relative to a receiver, the attenuation vs distance can vary from .9db per kilometer up to 5 db/Kilometer for high humidity per Bulletin Number 70 entitled "Millimeter Wave Propagation: Spectrum Management Implications" published by the Federal Communications Commission,July 1997.

Far as your other statements,I pointed out that a device is currently being developed to detect metals by their frequency. When you start researching Millimeter/THZ technology,you quickly realize that it is so cutting edge it's still in the labs at Universities or big companies. Do a google search on Millimeter cameras or THZ imaging and take note of the URL's.

So be patient Steve, Technology will catch up to your wishes. The equipment is VERY expensive. Oh yeah you can go to Virginia Diodes http://virginiadiodes.com/ and window shop. Just imagine what all that nice precisely machined stuff must cost to coble together a working receiver.

Also let it be known that my reply to Theseus was to let him know that technically gold and other materials do emit RF but I in no way was implying that these are what LRL/MFD/dowsers are responding to. And actually gold will give off ions if excited by ultaviolet light at 244nm which is under the topic of photoion emissions. Problem with the ions are they drift away and so with photoion emissions it is done in a vacuum to prevent this so that blows away (oops,no pun intended here) the "detecting gold by ions" theory.
