Night Vision Biocular gives you the tactically advantageous flexibility to choose where and when you get set up. Biocular viewing is a compromise between binocular and monocular design, and offers benefits from both worlds. The reduced size and improved depth perception make this style NVD a favorite amongst many night vision professionals. Inside this rugged, well designed unit lies a 2nd generation intensifier that lights up the night and delivers an astounding level of resolution (36-57 lp/mm). Second generation NVDs present a great value to the user while providing excellent levels of performance.
