Digital Night Vision Binocular and Night Vision Monocular are fast becoming a very popular 'must have' product for the wildlife enthusiast, and they are much more affordable than ever before. Price and performance are harder to tell apart with the advanced but cheaper technology of digital night vision optics. Whats more, because the optical image is now converted into a digital signal it naturally follows that it can be stored on a memory card as photo or video. Even better, most night vision optics can now be used during the day as well as at night, two for the price of one!
