Hawke Sport Optics 8×42 Frontier ED X Binoculars (Green)

Description

Track fast-moving woodland wildlife across an expansive 426-foot field of view using the Hawke Sport Optics 8×42 Frontier ED X Binoculars (Green) high-performance roof prism optical system. Pairing an optimal 8x magnification with 42mm objective apertures, this field optic delivers an expansive 426-foot linear field of view at 1000 yards (141.4m at 1000m), an actual angle of view of 8.1 degrees, an accommodating 5.25mm exit pupil, and 18mm of eye relief for rapid target location and comfortable handheld scanning during all-day field surveys.

The optical system features extra-low dispersion (ED) optical glass elements paired with high-resolution phase-corrected BaK-4 roof prisms treated with dielectric mirror coatings, broadband fully multi-coated surfaces, and water-repellent outer coatings. Built inside a lightweight magnesium alloy chassis encased in textured dark green protective rubber armoring, the housing measures 14 by 12.2cm (5.5 x 4.8 Inches) and weighs 692g (24.41 oz). The internal barrels are dry nitrogen gas filled and O-ring sealed for waterproof and internal fogproof protection against heavy downpours. Mechanical adjustments include a central focus wheel with 1.5-turn travel from a 6.6-foot (2m) close focus distance to optical infinity, a right-eye diopter adjustment ring, replaceable twist-up click-stop eyecups, an interpupillary distance range from 56mm to 74mm, and a standard 1/4-20 threaded tripod adapter socket.

Key Features of Hawke Sport Optics 8×42 Frontier ED X Binoculars (Green)

Built for demanding birders, hunters, and naturalists, this 8×42 roof prism binocular combines extra-low dispersion ED glass with dielectric-coated BaK-4 prisms. Its wide 8.1-degree actual field of view delivers edge-to-edge image sharpness with minimal spherical distortion. The nitrogen-sealed magnesium chassis, water-repellent lens coatings, and replaceable twist-up eyecups ensure dependable mechanical control and optical clarity across wet woodland habitats.

• 8x magnification power paired with 42mm objective lenses delivering a bright 5.25mm exit pupil
• High-resolution BaK-4 roof prisms treated with phase-correction and dielectric mirror coatings
• Extra-low dispersion (ED) optical glass elements eliminating chromatic color fringing
• Expansive 426-foot linear field of view at 1000 yards (141.4m at 1000m) with 8.1-degree actual angle
• Generous 18mm eye relief with replaceable multi-stop twist-up rubber eyecups for eyeglasses
• Precision central focus wheel with 1.5-turn travel and a 6.6-foot (2m) minimum close focus limit

• Water-repellent protective coatings applied to exposed objective and ocular lens faces

Extra-Low Dispersion Glass & Dielectric-Coated BaK-4 Prisms

The optical configuration integrates extra-low dispersion ED glass elements to suppress secondary spectrum chromatic aberration, preventing purple and green color fringing on high-contrast edges such as perched raptors against bright overcast skies. Dielectric multi-layer mirror coatings applied to the BaK-4 roof prisms maximize photon throughput, delivering high image brilliance and authentic color contrast during low-light dawn and dusk observation hours. Broadband anti-reflective multi-coatings minimize internal reflections, providing sharp clarity across the entire visual field.

Submersible Magnesium Alloy Chassis & 1.5-Turn Fast Focus

The rigid magnesium alloy housing provides structural durability to protect internal prism alignments from mechanical impacts while maintaining balanced handling in the hands. Textured dark green rubber armoring absorbs shocks and offers a secure hold in cold, wet conditions. The central focus wheel operates with smooth mechanical resistance through 1.5 rotations down to 6.6 feet, while water-repellent lens coatings cause rain droplets and condensation to bead and roll off without leaving residue, ensuring clear vision in rainy weather.

• Central focus wheel with smooth 1.5-turn gearing providing rapid focal control down to 6.6 feet
• Submersible nitrogen-purged magnesium alloy chassis engineered to resist heavy field impacts
• Replaceable twist-up eyecups with position stops ensuring repeatable, stable eye relief alignment
