MOPED ARMY

I dont have the money for anything else now, this is the temp gun i use in my shop for working on cars and its usually only ever reads about 5-10 degrees below. i checked it against other temperature gauges I've tested it against other temperature gauges on cars from time to time. when i boil water on the stove it will read about 207 which isnt far off from the 212 its at. so for now its all i have to go on
