The Snooperscope ($99) lets you use your mobile device’s screen to see in total darkness. It employs special optics and infrared lights so you can see any area covered by the light even though you only see total darkness with your eyes. The Snooperscope comes with a threaded and a magnet mount so you can use different mounts in different situations. Like in car, on a wall, or on your bike. It comes with iOS and Android Apps, and an on-board battery that provides up to 4 hours of use.
