The only problem I have with the O'donnel temp gun is the lights really kills the battery. I broke in my novarossi on a prop I was constantly checking the temp before i was done the battery was dead. So I went inside and disabled the light ckt. Now the battery last an entire season.
One thing to remember about temp guns is to know if it is a (OP-Offset point or CP -centerpoint) Most Raytek's are OP meaning where ever the lazar points you are actually measuring 1 inch to right of the lazar dot no matter what the distance to spot ratio is. So if you place an OP type temp gun directly over the heat sink you are actually reading down the side of the heat sink not the glow plug.
