From the renowned A-series, the 10x32 Ad Series Ed Waterproof Roof Prism Binoculars are the first to feature Ed (Extra-low Dispersion) glass elements. These elements ensure a crystal-clear, high-contrast view of the image field, effectively compensating for chromatic aberration. As part of the Ad-series, these binoculars boast a roof prism design with objective lenses, offering impeccable viewing quality. These binoculars are the compact, portable, and durable counterpart to the S-series, providing the convenience of mobility without compromising on optical performance. The advanced coatings, including fully multi-coated lenses, phase correction, BaK4 prism, and a new enhanced light transmission coating, deliver sharp images and superb contrast. Designed for comfort and ease of use, these binoculars feature an inner focusing mechanism, a fully rubberized body, a focus wheel, and twist-up eyecups.
