The DNVM-4 4x42 Digital Night Vision Monocular from ATN is a handheld optic built for low-light observation. Unlike analog NVDs, this device uses a digital sensor that is sensitive to infrared light. Using the DNVM's built-in infrared illuminator, this monocular can see in complete darkness. Adjustable gain and a manual focus objective lens equip the DNVM with features needed to meet a wide range of recreational viewing tasks. An ergonomic grip, compact form factor, and water-resistant housing make the DNVM-4 monocular easy to handle and well-suited for low-light imaging on a budget.
