| Untitled document NVS 7-2/WA (Wide Angle) breaks the common conception of night vision goggles design. No more 'tunnel vision'! By using the advanced 25 mm tube we get 60 degrees Field of View that provides 2.5 times larger spatial angle (58% horizontal x 58% vertical) than a conventional 40 degrees design.
