The Discovery 5x Gen 2+ HD Night Vision Bi-Ocular from Armasight is a generation 2+ NVD capable of up to 72 lp/mm resolution. The Armasight Gen 2+ HD multi-alkali photocathode's performance approximates a 3rd generation image intensifier tube; it also features Automatic Brightness Control, which continuously adjusts image brightness to optimize the displayed image quality. This night vision device comes with a hand strap, neck strap, and features a standard 1/4"-20 tripod mount.

A 108mm f/1.15 lens system displays a 9.5° field of view and can be focused as close as 10', making the Discovery Gen 2+ HD bi-ocular ideal for close-range and other viewing tasks. The bi-ocular configuration is designed to allow the user to keep both eyes open for more comfortable long-duration viewing. Combined with a removable IR illuminator and weather-resistant housing, this bi-ocular is well-equipped for observations—low light or no light, indoor or outdoor.
