The M-Spector 360 digital inspection camera has a 2.7-inch high-resolution color LCD screen that rotates so you don’t have to stand on your head to figure out what the heck you’re looking at. Its .35-inch camera head is fitted with four LED light units and yields a pixel density of 640x480. Part of Milwaukee’s 30-tool M12 lithium-ion line, the camera comes with a 3-foot or 9-foot cable; the 9-foot model — with battery, charger, and accessories — costs about $230. The bare tool costs about $130.
