Thermal imagers are only capable of measuring the infrared radiation (temperature depented) from the outer "skin" molecules, thats why when we measure a bearing protected with a cup in contact with it we assume that the bearing is at least 10 degrees celcius hotter than the cup. Although i was sure about this i made some tests with my camera (50000€ price) with metal plates burried at depths from 10 to 30 cm and i saw nothing worth mentioning. And i tried with every possible configuration (emmisivity, temperature windows etc).Anyway if someone is still interested in learning more about thermal imagers i would like to help.

Hi airman21,
Thank you for professional insight.
The majority of Geotech members (with some notable exceptions
) are already convinced that the use of laser thermometers to find buried treasure is complete nonsense. However, a select few are insisting on flogging a dead horse.
It would be very interesting if you could post some images of your experiments with the buried metal plates.
