Endurance ED 25-75x85 Spotting Scope from Hawke Sport Optics
Designed for long-distance viewing, the Hawke Sport Optics Endurance ED 25-75x85 Spotting Scope with 45° angled viewing delivers bright, crisp, and high-resolution images across its entire magnification range. Its optical performance is enhanced by high-quality glass and specialized coatings. The extra-low dispersion (ED) glass corrects chromatic aberrations, boosts contrast, and improves color accuracy, while fully multicoated, anti-reflection lenses prevent light loss and enhance resolution and contrast. To maintain true color fidelity across the visible spectrum, the BAK4 Porro prisms are coated with highly reflective dielectric coatings, reducing light loss and enhancing contrast and color accuracy. This combination of premium optics and coatings ensures bright, clear, and high-contrast images, even at maximum magnification over long distances. The Endurance ED spotting scope features a two-speed focusing system, allowing for rapid coarse adjustments as well as precise fine focusing, perfectly complementing its wide zoom range. The 45° angled viewing design provides a more comfortable viewing experience than straight-through models, and the scope body can be rotated relative to the tripod mount to achieve the ideal eyepiece positioning. Built with a polycarbonate chassis, the scope is corrosion, impact, and temperature resistant, with nitrogen-filled optical tubes that are water and fogproof, ensuring reliable performance in harsh weather conditions. Additionally, the scope's 1/4"-20 mount makes it compatible with a variety of tripods, quick-release plates, and support systems such as window mounts. |
Optical Performance, Use and Handling, and Construction Details
The Hawke Endurance ED 25-75x85 Spotting Scope is optimized for long-distance observation, offering a powerful 25-75x zoom eyepiece that allows users to see fine details, even across wide expanses. Its large 85mm objective lens ensures bright, crisp views, even in low light or at maximum magnification. The extra-low dispersion (ED) glass corrects chromatic aberrations for enhanced contrast and true-to-life color, while the fully multicoated, anti-reflection optics maximize light transmission, improving contrast and color accuracy. With a BAK4 Porro prism design for edge-to-edge sharpness and dielectric prism coatings that reduce light loss, the scope provides sharp, high-contrast images. The field of view is 90 feet at 1000 yards at 25x magnification and 46.5 feet at 75x. The 45° angled eyepiece makes viewing comfortable from various positions, whether standing, sitting, or lying prone. A dual focusing system allows for fast coarse and precision fine adjustments, with slip-resistant focusing knobs that are easy to use even in wet or cold conditions. The twist-up eyecup offers customizable eye relief, and the 1/4"-20 mount ensures compatibility with most tripods and support systems. With a long 20mm eye relief and a comfortable 3.4mm exit pupil at 25x, this spotting scope is ideal for extended glassing sessions. Built with a lightweight, temperature-resistant polycarbonate chassis, the scope is durable and virtually immune to the expansion and contraction issues that can affect metal chassis over time. It’s nitrogen-filled and sealed to be waterproof and fogproof, ensuring reliable performance in extreme conditions. A retractable sunshade reduces glare and lens flare, while a stay-on/view-through soft cover offers maximum protection without hindering access to key features like the tripod mount, focuser, and eyepiece. The flip-down objective lens cap keeps the lens protected and ready for quick viewing opportunities. |
