What could be more fun than running around shooting a laser at various items to take temperature readings? Okay, that may be somewhat childish, and after all this is a tool, not a toy. However, it is fun to see what temperature your dog's tongue is, or how cold your beer is with and without a coozie. Yet, you can also use this handheld digital infrared thermometer for detecting leaks in your home's ac and heat. Or if you are a gearhead like our boss, then you can check the temperature reading per each cylinder on your sports car. Seriously, we watched him do it.
