i would buy a more expensive temp gun but I'm not a breeder or breeder yet and right now I only have 3 ball pythons. I need to buy one because my thermometers are acting weird. I have my thermometer probes taped on the heat tape and when I took a snake tub out of the rack to clean it, the temperature on the heat tape became 86-92 from 91-95. I mean how the hell does that happen. Like when my thermostat would change the thermometer would be the same degrees as the thermostat many +/- 1 or 2 degrees and now the temperatures from my thermometer are way different from the thermostat.
