The thermal leak detector makes it easy to monitor your home's energy efficiency by finding areas that let heat out and cold air in. Simply set the detector's temperature tolerances to one, five, or 10 degrees and scan the light across the area you want to inspect. The light will change to red for warmer spots and blue for cooler spots to detect air leaks in both warm and cool weather. The detector also displays temperatures in either Fahrenheit or Celsius on the LCD screen. Check for drafts or leaks around your fireplace, recessed lighting, electrical outlets, along floor molding, or any place that may have improper seals, caulking, or seams that aren't immediately visible. An included booklet gives you tips and instructions on how to seal leaks and improve insulation.

Diagnose engine problems related to overheating or coolant leaks to avoid costly repairs and mechanic bills down the road. The thermal leak detector can also check the operation of your HVAC system, so you can perform preventative maintenance as needed.

wanted to like it
I'd wanted this for so long and then it was a disappointment. Maybe my needs weren't a good fit for it because it seems to be effective for others. When I used it on windows where I could feel there was some cold air coming in, it would be a few degrees lower, as you'd expect. So didn't tell me much. And the number jumped around too much to be finely accurate. The cone in which the rays or whatever shoot out probably makes a huge difference; the aiming device should help you keep that consistent.The final straw before I returned it was when I could feel gusts of cold air in my basement coming out from around a wooden panel board that wasn't doing jack, and this thing was acting exactly like it did every other time, showing a degree or two colder. And I'm not sure how it got its reference value. I read the instructions, but as soon as you turn it on, it grabs a reference value, so I guess the lesson is to be aiming it at the right spot when you turn it on.
