Why inexpensive IR temperature gauges are bad!

Inexpensive IR temperature gauges are sensitive to radio transmissions. Link to a small inexpensive IR temperature gauge with a notice about radio transmissions:
http://manuals.hobbico.com/dtx/dtxp3100-manual-v1_1.pdf
This manufacturer tells customers about the problem because they sell radio control vehicles and related equipment and using their gauge around their products will likely lead to problems.

IR temperature gauges operate on the principal that objects radiate heat. The amount of heat radiated is known as it's emissitivity - remember that college physics class on black body radiation that probably all of us slept through. Normally you do not know the emissitivity of the surface of the object you are measuring the temperature of and so you cannot calibrate the IR gauge to the material. Link to a table with emissitivity of various materials: http://www.engineeringtoolbox.com/emissivity-coefficients-d_447.html

So as you radio to your team that you have found this strange cold spot that you can't feel but you can measure... you have just confirmed that you are a fool, now go sit in the corner and study your orb pictures.
