When you need a thermal weapon sight that lets you move from rifle to helmet or hand-held use with ease, look no further than N-Vision Nox. This unique product is proudly designed and built in the USA, using the best commercially available 640 x 480 60 Hz BAE thermal imaging core and the highest grade optical components. Nox features a manual focus, non-rotating wide field of view 35mm F1.1 Germanium Lens to provide the best image quality in any weather conditions. Weapon and dovetail mounts are removable to reduce the unit’s size and weight to help achieve optimal NOX configuration. Each Nox ships with a standard CR123 battery, rechargeable 18650 battery and a charger. Depending on ambient temperature, you can expect up to an hour of run time with a standard CR123 battery and four to seven-plus hours on the rechargeable 18650 battery. Nox's five ergonomic control buttons permit immediate access to calibration, polarity, zoom, photo, power and user-friendly menu system for zeroing and customizing device parameters. The dedicated calibration button gives the user ability to calibrate the unit with one hand in under one second.
