I've had a little bit of experience with digital IR thermometers. My husband recently got a thermometer that looks just like this but a different brand, and that thing was highly inaccurate! This thermometer, however, was spot on accurate and I'm very pleased with it!
Once you turn on the thermometer, it is automatically on Celsius for some reason. You have to press and hold the mode button for a few seconds for it to switch over to Fahrenheit. There's memory settings where you can store up to 20 readings with a LOG function. The memory function also automatically recalls your last reading. The minimum reading is -58 F and the maximum is 1202 F , which is a very broad range to measure just about anything you can possibly think of. You can also adjust the temperature from .10 - 1.0 degrees to ensure accurate measurements. There is a handy backlight that you can toggle on or off independently of the laser. There is an automatic shutoff of 15 seconds on the laser to help conserve the battery.
This thermometer is very accurate. I tested it out by trying my son's temperature. Within a few seconds, it gave me a completely accurate reading of 86.0 of his forehead. I tried to capture it in the photo, but by the time I got my camera centered, I moved the laser and the temp went down a fraction of a degree. Still, it was very accurate and gave me a lightning quick reading. I'm very impressed with the accuracy and the range of functions with this IR thermometer!
