Review on Discover Hidden Thermal Changes with BLACK+DECKER TLD100 Thermal Detector by John Maynard

My utility bills are higher than they were last summer. So I decided to try the switches in the panel. I found out that one of my overhead heaters was on which was causing extra traction. I didn't notice because my AC was running and cooling. This block clearly showed the temperature difference between the switches. The abnormal one had a 10 degree difference! I was skeptical about using this product on switchboards as none of the reviews mentioned switchboard use. but he did his job! Better than spending $1,000 on a FLIR thermal imaging camera (I agree FLIR is fast, but I can save a few seconds in exchange for $1,000)
