The IGen NV20/20 is a night-vision monocular that magnifies by 2.6 times what you are looking at. According to our friends from Random Good Stuff, this devices is twice as sensitive as previous generations, amplifying the ambient light 650 times (note that you still need *some* light). In total darkness conditions and at short range, just use the integrated infra-red light (illuminator, in blue on the photo).
In automatic mode, the monocular will adapt itself to the darkness conditions but it is also possible to select the aperture time (to capture more light), at the expense of the frame rate (number of images per second).
Now the interesting part: it is possible to connect this night-vision monocular to a video-recording device: great for filming wild animals eating your flowers at night! Product page
