product description:
Product description:
The KWY279D-21/31 It uses a high-performance second-generation/third-generation image intensifier, with excellent performance, small size, light weight, and metal housing. The distance between the eyes is adjustable, the imaging is clear, the operation is simple, and it is cost-effective. The magnification can be changed by changing the objective lens (or connecting the extender). The night vision device has a built-in infrared auxiliary light source and an automatic anti-glare protection system.
