GPO USA 8×42 Passion ED Binoculars (Deep Green)

Description

Carried through dense pine forests and wet coastal swamps in a non-reflective deep green finish, the GPO USA 8×42 Passion ED Binoculars (Deep Green) deliver high-contrast resolving power and broad situational awareness for mobile birders and backcountry hunters. Pairing an optimal 8x magnification with 42mm objective apertures, this field optic provides a wide 375-foot linear field of view at 1000 yards (124.5m at 1000m), an accommodating 5.3mm exit pupil, and an expansive 19.5mm eye relief for rapid target location and comfortable, fatigue-free scanning during extended surveys.

The optical system features 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 outer lens coatings. Built inside a compact magnesium alloy chassis with an ergonomic micro-bridge design and deep green protective rubber armoring, the housing measures 130mm (5.1 Inches) in length and weighs 830g (29.3 oz). The optical barrels are nitrogen gas filled and O-ring sealed for complete waterproof and fogproof protection against adverse outdoor weather. Mechanical controls center on a smooth central focus wheel with an agile 6.5-foot (2m) close focus distance, an integrated diopter adjustment dial spanning -4 to +4, solid aluminum twist-up click-stop eyecups, and an interpupillary distance range from 57mm to 75mm.

Key Features of GPO USA 8×42 Passion ED Binoculars (Deep Green)

Built for nature photographers, birdwatchers, and hunters seeking optical clarity in an agile format, this 8×42 roof prism binocular combines extra-low dispersion ED glass with dielectric-coated Schmidt-Pechan prisms. Its 5.3mm exit pupil produces bright, high-contrast imagery in shaded woodland canopies. The nitrogen-sealed magnesium chassis, deep green rubber armoring, and machined aluminum eyecups provide all-weather reliability across rugged outdoor terrain.

• 8x magnification power paired with 42mm objective lenses producing a bright 5.3mm exit pupil
• Phase-corrected Schmidt-Pechan roof prisms treated with high-reflectivity dielectric mirror layers
• Extra-low dispersion (ED) optical glass elements eliminating chromatic color fringing
• Linear field of view of 375 feet at 1000 yards (124.5m at 1000m) for wide-angle scanning
• Generous 19.5mm eye relief with solid aluminum multi-position twist-up eyecups for eyeglasses
• Central focus wheel with an agile 6.5-foot (2m) minimum close focus limit and -4 to +4 diopter range
• Airtight nitrogen-purged magnesium alloy chassis certified waterproof and protected against fogging
• PASSIONdrop water, dirt, and oil-repellent protective coatings applied to exterior lens faces

Extra-Low Dispersion Optical System & GPObright Coatings

The 42mm objective lenses utilize extra-low dispersion ED glass to minimize internal light reflection and suppress chromatic fringing across high-contrast edges. GPObright multi-coatings maximize light transmission through the entire optical train, yielding rich color saturation and high optical contrast when glassing shadowed coulees during dawn and dusk feeding hours. PASSIONdrop hydrophobic coatings cause rain, morning dew, and dirt to slide off exposed lenses, preserving an unobstructed visual field in humid weather.

Deep Green Magnesium Chassis & Extended 19.5mm Eye Relief

The magnesium alloy chassis features an ergonomic micro-bridge architecture that distributes weight evenly across the palms, reducing muscle fatigue during long glassing sessions. 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 down to 6.5 feet, while the deep green rubber armoring blends naturally into forest foliage while absorbing field shocks.

• Central focus barrel providing fluid, micro-fine focal adjustments down to 6.5 feet
• Submersible nitrogen-purged magnesium alloy frame encased in non-slip deep green rubber armoring
• Solid aluminum twist-up eyecups with distinct click-stops ensuring repeatable eye relief alignment
