Hey thanks. Lucky for me I dialed that in years ago. I have been using this one on cars for about ten years & it was not cheap. Its dead on with my laser pyrometer and actually preferred over the digital new-fangled battery powered probe that this one sits next to (battery's are plain not reliable).

So how about that!?
