Binocular Head-mounted Night Vision Device YJSPK2-3
Product Description
YJSPK2-3N&D binocular binocular night vision device is a high-performance pure head-mounted night vision device built with reference to the active head-mounted night vision device PVS-31 in the United States. It is divided into low-light version YJSPK2-3N and digital version YJSPK2-3D two models.
The digital version of YJSPK2-3D has the characteristics of strong adaptability to ultra-low illumination environment, high imaging quality, multi-function, day and night, electronic zoom, clear imaging, high cost performance, etc. It is very suitable for general military fans and night outdoor enthusiasts. . The low-light version YJSPK2-3N has the characteristics of large field of view, high definition, no distortion, light weight, and high strength (the overall performance greatly exceeds the original US military product) and is an ideal choice for night equipment.
