Higher quality lens and optical arrangement. Most importantly, 11:1 optics mean the I.R.F.S. reads a smaller spot diameter at a greater distance.

To operate, just pull the trigger and point the laser at your subject. The display updates instantly and locks the reading when you release the trigger. The Max function records the highest temp during the scan. No complicated buttons or settings. Emissivity is preset to 0.97 for more accurate general use in food and frozen food applications. Other than the “On” trigger, the only other button is the °C/°F button which is in a handy spot on the display panel. No more digging inside the handle to change scales.
