The EMF2 Extendable Flashlight is a low-tech alternative to a digital inspection camera. It has a telescoping body, a flexible neck, and three LED lights. The tool is 6-1/2 inches long in the tuck position and 21 inches extended. Both ends are magnetic. You can use the rear magnet to attach the light to a beam, an electrical panel, or a furnace housing, and the front one to retrieve screws and other fallen objects. Attaching a pivoting inspection mirror to the front of the flashlight allows you to see around corners.
