I don't think the pro exotics temp guns have a laser so you don't have to worry about cooking an eyeball.

remember that the temp gun only gives you an average of the temp within a circle 'X' far away from the gun. Most of them are 1:1 so the temp is a 1 inch diameter circle 1 inch away from the device, or a 12 inch circle 12 inches away from the device. Any further away then 12 inches and it's not going to be very accurate.
