Okay so here goes..
First off I am sorry to ramble but this post just brings me to a question of Why? I guess basically I just cant understand why you should want or need a tool of such nature. ( I understand the need to temp,, ) but when does it become so critical to know that my tool ( an exergen standard $70 jobby
) is less accurate by 7 * than said other temp gun at 2 inches?
I guess I will skip to the bottom line.. This hobby is expensive enough why make it more when you dont need it. If you have a need for such tools buy them ( ie this is not the only place you will use it, and in that place you need that accuracy! ) by all means get and growl!!....
But we dont tune to temp atleast you shouldn't.. so if your motor is happy and your gun says its within a good heat range ( ive had motors run anywhere from 220 to 270 depending on motor) then why would you need an exact temp when your only temping mainly for your own peace of mind..?
