Something that can detect heat like IR seems more likely to me if there is a temperature difference in the soil.

Gold generating it's own EMF radiation is one thing, but we all know that it is capable of re-generating signals it receives, as it does with metal detectors!
It is also known that everywhere on this planet is flooded with various types of radiation, either from the sun, or other natural and man-made sources.
When you consider that mix, plus the various chemicals and minerals associated with gold deposits, or even just surrounding buried gold coins or bullion, all interacting, there are a lot of possible factors to consider.

I agree. But see my post #428, above.
Hardscrabble said:Don Jose... seriously though, exactly what are the metals in question (gold for example) emitting that gets picked up? As I stated before, I would think that gold is pretty stable. That being said, I could more see some device emitting waves that somehow "excite" the metal at the molecular level and in the process spark radiation (popping electrons?). In that case what would be detected are those particle emissions. But, wouldn't that take some pretty fancy and powerful equipment to accomplish - if it's even possible?

Thanks EE THr ~ So do you think the gadget I mentioned above might be possible?
