Insight night vision accessories can be used in conjunction with night vision devices to either expand their functionality or their lifespan. Many weapon accessories, like laser sights and IR illuminators, can be coupled with night vision devices for maximum efficacy. Insight Technology manufactures a variety of night vision accessories that accompany their monoculars, binoculars, and other night vision devices. A Night Vision Tester from Insight is a key element to determining if your night vision device is working properly, or you can purchase an Insight laser sight to use with your Insight Tech night vision equipment for precision shooting in the dark. Night vision accessories by Insight Tech vastly improve the usability of most standard night vision devices.
