GPO USA 10×56 Passion ED Binoculars

Description

Built for deep-twilight big-game scouting and stationary blind glassing, the GPO USA 10×56 Passion ED Binoculars provide high optical brightness and resolving power for low-light observation. Combining 10x magnification with massive 56mm objective apertures, this high-performance roof prism instrument yields a 352-foot linear field of view at 1000 yards (116.9m at 1000m), an expansive 5.6mm exit pupil, and 16mm of eye relief for comfortable, strain-free viewing during low-light observation vigils along dark timber edges.

The optical system features high-resolution extra-low dispersion (ED) optical glass elements paired with phase-corrected Schmidt-Pechan roof prisms treated with dielectric multi-layer coatings, GPObright broadband multi-coatings, and PASSIONdrop hydrophobic exterior lens coatings. Built inside a durable magnesium alloy chassis with a micro-bridge design and black shock-absorbing rubber armoring, the housing measures 19.1cm (7.5 Inches) in length and weighs 1171g (41.3 oz). The optical barrels are nitrogen gas filled and O-ring sealed for complete waterproof and fogproof protection against adverse mountain weather. Handling mechanics feature a central focus wheel with an integrated locking diopter adjustment, a 9.8-foot (3m) close focus distance, solid aluminum twist-up click-stop eyecups, and an interpupillary distance range from 58mm to 75mm.

Key Features of GPO USA 10×56 Passion ED Binoculars

Engineered for hunters monitoring food plots and clearings in fading daylight, this 10×56 roof prism binocular combines extra-low dispersion ED glass with massive light-gathering power. Its 5.6mm exit pupil fully illuminates dark-adapted eyes during dawn and dusk feeding hours. The nitrogen-sealed magnesium chassis, integrated locking diopter, and PASSIONdrop lens coatings provide structural durability and optical clarity across demanding outdoor environments.

• 10x magnification power paired with massive 56mm objective lenses producing a bright 5.6mm exit pupil
• Phase-corrected Schmidt-Pechan roof prisms treated with high-efficiency dielectric mirror coatings
• Extra-low dispersion (ED) optical glass elements delivering clean color rendition without fringing
• Linear field of view of 352 feet at 1000 yards (116.9m at 1000m) for broad situational awareness
• Comfortable 16mm eye relief with machined aluminum multi-position twist-up eyecups for eyeglasses
• Central focus wheel with an integrated central locking diopter dial and 9.8-foot (3m) close focus
• Airtight nitrogen-purged magnesium alloy chassis certified waterproof and protected against fogging
• PASSIONdrop water-and-dirt-repellent protective coatings applied to exterior objective and ocular surfaces

56mm Light-Gathering Objectives & GPObright Multi-Coatings

The 56mm front objective elements utilize extra-low dispersion ED glass to optimize photon throughput, generating a large 5.6mm exit pupil that matches the human eye in deep twilight. Dielectric mirror coatings and phase correction on the Schmidt-Pechan prisms eliminate internal optical interference, preserving crisp edge resolution and authentic color separation on camouflaged game. GPObright multi-coatings maximize light transmission through the entire optical train, allowing observers to resolve game contours deep within shaded timber during fading twilight.

Magnesium Micro-Bridge Body & PASSIONdrop Weather Armor

The magnesium alloy chassis features an ergonomic micro-bridge architecture that distributes weight evenly across the hands, reducing fatigue during long glassing vigils. Machined aluminum eyecup barrels provide structural durability and maintain precise click-stop detents to prevent eye relief collapse. The central focus wheel operates with calibrated mechanical resistance, housing an integrated pull-out diopter adjustment ring that locks securely into place, while PASSIONdrop hydrophobic coatings cause rain droplets and dirt to shed cleanly from exposed lens faces.

• Central focus barrel integrating a pull-to-lock diopter compensation wheel with micro-click detents
• Submersible nitrogen-purged magnesium alloy frame encased in protective black rubber armoring
• Machined aluminum twist-up eyecups with distinct click-stops ensuring repeatable eye relief alignment
