I worked on various types of IR systems for the military when I was a consultant doing all things wild and esoteric like image signal processing and I can verify with Carl - IR is a waste of time as a treasure hunting tool.  Save your money and buy a good metal detector  or if you can dowse get a couple of coat hangers.

Yes, the infrared thermometers are an amazing tool. They can be used to measure the temperature of skin, walls, rotating machinery, bearings, flames, and a lot of things that are harder to measure with other methods. But they suck for trying to find small buried items. If anyone thinks they may find some good treasure hunting results with an infrared thermometer, they don't need to spend $600 or more. The $30 Harbor Frieght model works just as well. The sensing parts are all the same. And you can find these on ebay new for a similar price. Try out the cheap model and see if it helps you find treasure. If it doesn't work for finding treasure, then you have a good tool for measuring temperature around the home and lab.
.... And you don't have the bad feeling you wasted $600 or $3500!
