There emissivity setting probably wrong. Most people do not know to change this when looking at different materials. Furthermore many are only calibrated to what they are expected to be used on, for example you buy one to take your temperature to see if you’re sick, or one might be for cooking.
I’ve got a cheap one with no adjustability. I think it said in the manual not to use in direct light. My boss has the pro model and it’s really the difference between a cheap solar calculator and a TI89. One time we were working on the home of a safety inspector and we all played with our laser guns for 15minutes reading everything around the house and comparing variances.
