National Geographic 9075500 5x Black monocular

5x50 Digital Night Vision Device The 5x50 monocular is a digital night vision device for use at short and medium distances. Incident light is electronically magnified to make observations possible at night. This device can also be used during the day if there is sufficient residual light, resulting in a colour image. The adjustable, integrated infrared illuminator makes use in absolute darkness possible. Still, the night vision devices are small and lightweight enough to be carried during all kinds of activities. This makes them suitable for camping, as well as for nature observation and other applications.
