If you care about energy efficiency, saving money, the environment or just plain have a drafty house, then take a look at this handheld gadget. The B&D Thermal Leak Detector uses infrared sensors to measure surface temperatures to show you where there are temp differences and hence leaks.
The TLD100 is easy to use: just set the tolerance level, point it at the area you want to check and read the LCD display.
Just imagine saving 20% on your heating and cooling bills and having a nice toasty/cool home. The TLD100 also comes with a booklet that describes how to plug leaks.
