Armasight NYX-14 is a rugged lightweight Multi-Purpose Night Vision Mini-Monocular that can be Hand Held, Camera Adaptable, Head/Helmet Mounted or Weapon Mounted. Armasight NYX-14 is based on “single tube/single eyepiece” concept where independent use of each eye maximizes the ability of the user to operate under a wide range of low light conditions while reducing the risk of temporary night blindness typically associated with night vision goggles. A built-in Illuminator allows you to see clearly even in total darkness. Armasight NYX-14 is available in two configurations, with variable gain control or automatic gain control. Limited two-year warranty The variable gain control allows the user to increase or decrease image brightness for best possible contrast in any situation. Armasight NYX-14 is equipped with state of the art Bright Light Cut-Off System which controls the existing illumination level through the photo receiver. When the illumination level surpasses 100-300 lx for the following 10 seconds, the Monocular will shut off automatically. NYX-14 can be use as a long range Night Vision Spotter in conjunction with state of the art 3x, 5x or 8x lenses. Armasight NYX-14 is everything an outdoorsman, fisherman, tactical shooter, or hunter could ask for.
