AC-2015 Daytime Binoculars are built from only the most exceptional quality glass to deliver a crisp and clear image. The glass features a special proprietary lens coating used in night vision technology to maximize light transmission for better performance in low light environments. The binoculars are built tough to withstand the harshest environmental conditions, including marine environments. Each binocular is completely sealed against dust, sand, and water, and also filled with nitrogen to prevent fogging of internal lens surfaces. It also features individual diopter focus for clearer images, and built-in range finder reticle (M22). Binoculars meet standards and requirements of MIL-STD810.
