Is IR for Real???

Not being argumentative here. Genuinely asking. Does the IR technique have any known scientific basis? And, are if you have actually used the IR technique to locate and excavate precious metals, please share your experience. Thanks.

In principle it can work in certain instances. If you have dry sand that is exposed to sunlight late in the day it can act as an insulator for gold which has a low emissivity. Then after sunset it might be possible to spot it with a very sensitive sensor. That is difficult to get all those conditions and even then it cannot be buried very deep. So the answer is very unlikely. It probably works better in equatorial area where sun angle is high and the sun sets very fast. Any moisture in the soil will bleed off any stored heat. The sensor has to be more accurate than your standard IR device, probably costs several thousand $.

I did some research on my own just minutes ago. Basically, IR cannot penetrate anything. Therefore only surface spectral anomalies can be picked up. So, if sub-surface mineralization (or treasure) has affected the surrounding medium up to and including surface level/surrounding flora, etc., then IR could pick up on it. But, unless whatever is under the surface has somehow altered the surface material thus making it sensitive to IR pickup, then no, IR is not a valid search method. Or, at least a primary one.

Using IR temperature device can find cave openings in the Winter and possible after a HOT day at twilight !

I use google earth to find gold or silver targets big or small as the targets show up as an anomaly mostly white in color in and out of the water.don’t know what kind of special cameras they are using but it picks up the gold or silver or any other metals in the ground or water areas.these are examples of real targets in and out of water.these red circle one is in my backyard and it’s a cast iron piece that is buried 5 ft deep.
