Infrared thermometer makes diagnosing cooling system very simple. Overheating engine, thermostat, fan switch, clogged radiator.
I guess, it is infrared, there is no description. Handgun type for $20 would be better probably.

I have one similar to the one below. Makes sure it is not a body temperature meter.
