You really don’t know what you are missing until you use a thermal imaging thermometer. There are a few on the market for the trades including the $2500 M12 Milwaukee imager which is a true thermal imager, the $900 DeWALT DCT416S1 imaging thermometer and now the $500 FLIR TG165. In short an imaging thermometer mixes a thermal image with a real image and emulates an imager. Unless you need high-resolution heat maps an imaging IR thermometer will do you just fine. It is amazing how fast you can troubleshoot with this device.
The unit has the ability to take a picture and save it to the included mini sd card. It has a 2 laser system to show you where it is taking the reading from. It can show both a color and grayscale image.
We like the FLIR TG165 the best out of the 3 tools mentioned above. It is a quick easy to use tool that any tradesman will appreciate. Best of all the $500 price tag makes it a no brainer. The only thing I would have liked to have seen was a cover or case for the unit. The instruments at the front are susceptible to damage when you store it in your tool bag.
