Hi Mike(Mont),
I also work with thermal imaging cameras. And I agree with airman21. I found these cameras are good for seeing framing behind a wall, or moisture in a wall, and for looking or thermal leaks in a building. They also can show the temperature gradients on the surface of nearly anything you take an image of. But these are still a little crude compared to what Nasa uses, and they are expensive compared to a professional digital camera.
I have never seen anything in the landscape outside a building that led me to buried treasure, buried pipes, or anything else buried except cold areas from wet spots and shadows. I can usually see where a parked car recently left it's parking space for a while, but no signs of things that I know are buried under the ground. But Randy's original question was not about the expensive thermal imaging camera. He asked about a cheap infrared thermometer. This is the same as using a light meter instead of a regular camera, except we are using a meter that measures infrared level instead of light level. Can you imagine that using a light meter would have anywhere near the image quality as looking into the back of a digital camera to try to identify what you detected?
For example: A digital camera may take a photo of a house with some trees that have shadows under them. You will be able to see the entire image of the house as well as all the details of the trees and shadows and other things. But using only the light meter, you will only know there are dark areas and light areas as the meter is moved around. You will have no clue whether you found some bright shiny gold or a reflection from a trash can or maybe a light bulb.
It is the same with thermal imaging. Can taking temperature readings all over the place similar to using a light meter a light reading survey work to identify your target? What fool would try to locate treasure with an infrared thermometer? One who believed advertising propaganda that says it has a cave detector built into it? Wouldn't a serious treasure hunter insist on a thermal imaging camera? And wouldn't he quickly learn that not even a thermal imaging camera finds the treasure?
Maybe I am wrong... So let's see all the treasures recovered using an infrared thermometer or thermal imaging cameras.
Best wishes,
