Hawke Sport Optics 25-75x85 Endurance ED Spotting Scope (Angled Viewing)

The lens elements are made of extra-low dispersion (ED) glass to correct for chromatic aberrations, increase contrast, and improve color rendition. Additionally, they are anti-reflection fully multicoated to prevent light loss and further boost contrast and resolution. To ensure accurate color across the entire visible spectrum, the BAK4 Porro prisms are dielectric coated. These coatings are highly reflective and minimize the loss of light while further improving contrast and color fidelity. This combination of coatings and optics creates a spotting scope that produces bright, clear, high-contrast images with accurate color transmission-even when observing subjects on maximum magnification at extremely long distances.

This iteration of the Endurance ED has a two-speed focusing system to allow for fast coarse and precision fine focusing, making it a perfect complement to the wide zoom range. The angled-viewing configuration sets the eyepiece at a 45° angle to the scope`s body, which places your head in a more comfortable viewing position versus straight-through viewing models, and the scope body can be rotated relative to the tripod mount for the perfect eyepiece positioning. The chassis is made of polycarbonate, which is corrosion, impact, and temperature resistant, and the optical tubes are nitrogen filled and sealed to be water and fogproof even in extreme weather conditions. A 1/4`-20 mount makes it compatible with many tripods, quick release plates, and other popular support systems like window mounts.

Optical Performance

• Optimized for observing at extreme distances across wide expanses
• Powerful 25-75x zoom eyepiece allows users to discern fine details
• Large 85mm objective lens ensures views remain bright and crisp even in challenging light conditions or when observing subjects on maximum magnification at long distances
• Extra-low dispersion (ED) glass corrects for chromatic aberrations for increased contrast and true color rendition
• Anti-reflection fully multicoated optics maximize light transmission to improve contrast and deliver accurate color fidelity
• BAK4 Porro prism design for better edge-to-edge sharpness and depth of view
• Highly reflective dielectric prism coatings to reduce light loss and boost contrast and resolution
• 90-foot field of view at 1000 yards at 25x power, 46.5 feet at 75x magnification

• The eyepiece is set at a 45° angle to the scope body to put the user`s head in a more comfortable position when standing, sitting, or lying prone
• Dual focusing mechanism allows for fast coarse and precision fine focusing to make finding and viewing multiple or moving subjects fast and easy
• Slip-resistant focusing knobs are easy to manipulate in cold or wet weather, even while wearing gloves
• Twist-up eyecup allows you to fine-tune your perfect eye relief with or without eyewear
• Standard 1/4`-20 mount is compatible with most quick release plates, heads, and photo/video/field tripods and other support systems
• Long 20mm eye relief improves viewing comfort by providing a generous eye box and reducing eyestrain for easier viewing, especially during long glassing sessions
• Comfortable 3.4mm exit pupil at 25x

• Lightweight, temperature-resistant, and durable polycarbonate chassis
• Chassis` temperature resistance virtually eliminates the expansion and contraction common with metal chassis that can cause the optical components to move out of alignment over time
• Nitrogen filled and sealed to be waterproof and resistant to internal fogging when moving through extreme changes in temperature and environmental conditions
• Built-in retractable sunshade helps to limit peripheral reflections and lens flare to improve contrast and prevent spooking animals and birds
• Included stay-on/view-through soft cover offers maximum protection for the spotter while retaining full access to the tripod mount, focuser, sunshade, and eyepiece
• Flip-down objective lens cap keeps the lens clean and protected with the ability to quickly react to glassing opportunities
