It is good for indicating temps and detecting trends. But they are vastly misunderstood tools. Many people have no idea how they work and over estimate their accuracy. I've got a really good one, a Fluke, and it is only accurate to 1% of the reading.

Read up on emissivity and understand the D:S ratio. Oh, and experiment with black tape.
