This device features a compact and ergonomic rubberized body design that allows users to have a secure one-handed grip. At the core of the monocular are a 1st generation night vision intensifier tube with a resolution of 36 lp/mm and a 2x optical system with a 28mm objective and wide 21° angle of view. The intensifier tube converts an infrared scene profile to visible imagery and will deliver bright and clear images during clear or partially cloudy nights. On very cloudy nights or in completely dark environments, you can turn on a built-in infrared illuminator, which will improve image visibility, brightness, and detail.
