I'm not sure about the PE-1, its one of the only temp guns I've seen without a laser aiming system. I don't believe the laser is what does the temp reading; it just helps with aiming to get an accurate reading. Some of the more advanced temp guns use multiple lasers to aid in getting the best reading. I'm no temp gun wizard though; just what I've read here and there.
As long as I don't give my snakes cancer, I'm happy
