A thermal leak detector can show you what parts of your garage require insulation. One of the factors in deciding to insulate your garage door is whether its allowing the heat or cool air from outside. The best thermal leak detector for the money is hands down the Black & Decker TLD100 Thermal Leak Detector. It’s not a $450 Flir camera, but for less than 1/10th the price, it accurately detects hot and cold spots.
This is the thermal leak detector that gives you instant feedback where your eyes are focused rather than just on the handheld screen. Many thermal detectors get this wrong. When you’re scanning the wall with the detector, you’re looking at the wall. Many detectors make you look back to your detector for results. The Black & Decker shines a light onto the wall where you are scanning. You don’t have to look at the tool interface to see your results.
Whatever the machine is pointing at when you turn it on determines the detector’s baseline temperature. The detector shines green, blue or red on the target object. A green light means the target is in the baseline temperature range. A red light means it’s warmer, and a blue light means it’s cooler. So you get temperature deviations in both directions from the baseline.

This thing saved me money $$$. Works on Circuit Breakers!!

I was getting a spike on my electric bill than last summer. So i decided to try this on the breakers in the panel. Found out that one of my ceiling heaters were turned on which was causing the additional draw. I did not detect it coz my AC was working and cooling down as well. This unit clearly showed the temp difference of the breakers. The abnormal one had a difference of 10 degrees! I was skeptical to use this product on electric panel since none of the reviews mentioned the use on electrical panels. but it did its job! better than spending $1000 on FLIR thermal imager (I agree FLIR is fast- but I can spare couple more seconds in exchange for a $1000)
