False.
When infrared radiation hits the surface of the ground, it is converted into thermal energy, which then propagates mostly via thermal conduction, not thermal radiation. Any buried metal will take on the temperature of the surrounding soil -- again via conduction -- regardless of whether it's gold or iron or whatever. Most metals, including gold, have very high thermal diffusivity compared to the surrounding soil, so they will tend to maintain the same temperature... that is, buried metal will probably not show a thermal lag.
Every dowser who has tried to show me that dowsing works has failed miserably. When someone takes my $25,000, then I will reconsider.
I have just purchased a MS6530 off eBay, for $59. Compare that to $2200 for the DIS-300.

I honestly don't agree with your statements above. You are not considering earth's own emissions regarding buried metals. But let's not waste time arguing.
At least now we can count on test on your part regarding the 6530?
