RE: Mini Temperature Guns! The "Hottest" Thing
The bad thing about the laser aiming point is that on some of the cheaper guns, $100 and less, it is offset from the point the reading is taken at the distances we normally use the gun at. If you move back to where the aim pint and the point the reading is taken match the area being read is so large the data does not mean anything.
They are great on buggies and trucks that you can pull right up to your feet quickly after a hard run and get a reading. Have not figured out how to do that with a plane except to crash it.
Where I have started using it is when breaking in an engine on the bench to make sure it is not getting too hot.
