I've just finished a new review of the ThermoHawk 200 from Q3 Innovations. This device is an infrared thermometer. Here's a short snip from the review:
The unit arrived in a nice package which was easy to open. No scissors were required. In the package I found the ThermoHawk 200 thermometer, two LR44 batteries and a manual. Put the batteries into the unit and you're ready to measure some temperatures. Or if you want to use Celsius instead of Fahrenheits you need to search for a paperclip or something similar to push into the small hole on the back of the unit. This will switch the device from Fahrenheit to Celsius and vice versa.
