GT-14 Night Vision MonocularGT-14 is a tactical night vision monocular developed and manufactured by N-Vision Optics for the most advanced professional users who require superior quality, outstanding reliability, and unbeatable performance. GT-14’s unique ergonomic design allows very comfortable single-handed operation and dramatically minimizes the probability of user errors in extreme conditions. The monocular is equipped with an invisible to the human eye short range IR illuminator to assist with tasks that have to be performed in complete darkness, such as map reading, equipment repairs, etc. GT-14 features automatic brightness control (ABC), which automatically adjusts the brightness of the image intensifier tube for varying light conditions and in-ocular low battery and IR indicators. An ideal multi-purpose system for night time operations, GT-14 can be hand-held as a monocular, head/helmet mounted as a single-eye goggle, weapon-mounted as a night scope or attached to photo/video cameras and 3x/5x afocal attachment lenses. Also available is the dual mount adapter which allows 2 GT-14 monoculars to become one dual tube binocular system.
