Thermal Leak Detector
This is not what it sounds like. It is actually a device that helps you detect where you are losing heat out of your house. You can see where you are losing it near the window and under the door. This is a gadget that allows you to make your house more energy efficient by showing you where the heat is getting out or where the cold is getting in.
