Superior Optical PerformanceEngineered for exceptional long-distance observation, the Hawke Endurance ED 25- 75x85 Spotting Scope delivers crisp, high-contrast images with remarkable color accuracy. Its large 85mm objective lens provides bright views even in low-light conditions, while the extra-low dispersion (ED) glass eliminates chromatic aberrations for improved contrast and true color rendition. Fully multi-coated optics and dielectric-coated BAK4 Porro prisms ensure maximum light transmission, edge-to-edge sharpness, and outstanding resolution—even at full 75x magnification.Comfortable and Precise HandlingThe angled 45° eyepiece design promotes a natural and relaxed viewing position, whether you’re standing, sitting, or prone. Its dual-focus system combines fast coarse adjustment with fine precision control, making it easy to track subjects and refine focus. Twist-up eyecups offer customizable eye relief, while non-slip focusing knobs remain easy to use even with gloves. With a generous 20mm eye relief and a standard 1/4in-20 mount, this scope offers both comfort and compatibility for extended glassing sessions.Rugged, Field-Ready ConstructionBuilt with a lightweight yet durable polycarbonate chassis, this spotting scope is designed to handle harsh outdoor conditions. Its temperature-resistant body prevents optical misalignment, while nitrogen filling and sealed optics ensure waterproof and fogproof performance in extreme environments. A built-in retractable sunshade minimizes glare and helps prevent spooking wildlife, and the included stay-on/view-through cover offers full protection without sacrificing usability. The flip-down objective lens cap adds a quick layer of defense for the glass, ready for action at a moment’s notice
