Winter is here. And so, it’s time to fix those cold air leaks. That’s where Black and Decker’s Thermal Leak Detector comes in. Your current method of sliding your fingers down window seams until you feel cold air works okay, but the leak detector takes a high tech approach.

It detects temperature changes as small as a single degree. When it finds a trouble area where cold air is leaking in, a blue spotlight points you towards the problem. Pretty handy little tool for $40. Once it starts detecting leaks and you start sealing them, it will pay for itself in no time.

So the Predator is loose in your city, half your men are dead and it keeps making that eerie noise as it stalks you. Carl Weathers and Jesse Ventura were no help at all. Unfortunately, Predators have state of the art camoflage, so chances are, you won’t live very long to tell the tale…Unless you have something that can show you his heat source. Like this Handheld Thermal Imager for instance.

It combines a visible light digital image with an infrared one, producing a single view that lets you get an immediate visual temperature map of whatever you aim it at. It’s priced at about $7500. These thermal imagers are designed for heavy-duty industrial troubleshooting and safety applications, but there’s no reason you can’t use it to snag yourself a Predator before it detonates an atomic bomb from it’s wrist.
