Eschenbach Optik 8×56 Trophy D-Series ED Binoculars

Description

Eliminating low-light visual fatigue during deep-twilight big-game vigils, the Eschenbach Optik 8×56 Trophy D-Series ED Binoculars provide high optical brightness and resolving power for woodland hunting and nocturnal wildlife observation. Pairing 8x magnification with massive 56mm objective apertures, this German-engineered roof prism optic delivers a 304.5-foot linear field of view at 1000 yards (101.5m at 1000m), an actual angle of view of 5.8 degrees, a large 7mm exit pupil, and 11mm of eye relief for spotting cryptic game silhouettes in fading light without visual strain.

The optical system features BaK-4 roof prisms treated with phase-correction coatings and dielectric mirror depositions, paired with special extra-low dispersion (ED) optical glass elements and broadband high-transmission multi-coatings. Built inside a rugged magnalium (magnesium-aluminum alloy) chassis encased in black protective rubber armoring, the binocular measures 17.4 by 14.3 by 6.7cm (6.8 x 5.6 x 2.6 Inches) and weighs 1145g (40.39 oz). The internal barrels are dry nitrogen gas filled and O-ring sealed for complete waterproof and fogproof protection against severe weather. Mechanical controls center on high-quality metal adjustment wheels including a central focus drum with a 9.8-foot (3m) close focus distance, a right-eye diopter adjustment ring, retractable spectacle eyecups, an interpupillary distance range from 59mm to 74mm, and a stable 1/4-20 threaded tripod adapter socket.

Key Features of Eschenbach Optik 8×56 Trophy D-Series ED Binoculars

Engineered for low-light observation from tree stands and ground blinds, this 8×56 roof prism binocular combines extra-low dispersion ED glass with massive light collection. Its 7mm exit pupil delivers high light throughput during the final minutes of legal shooting light. The nitrogen-sealed magnalium alloy chassis, metal mechanical adjustment wheels, and multi-coated optics provide reliable durability and image contrast in all weather conditions.

Phase-Corrected BaK-4 Prisms & 7mm Exit Pupil Twilight Capacity

The 56mm objective lenses gather extensive photon volume, working with extra-low dispersion ED glass to suppress secondary spectrum chromatic aberration on high-contrast skylines. Phase-corrected BaK-4 roof prisms treated with dielectric mirror coatings maximize light reflection efficiency, preserving authentic color balance and high image brilliance across changing daylight conditions. The generous 7mm exit pupil floods dark-adapted eyes with available light, allowing hunters to differentiate game animals from shadowed background foliage during deep twilight.

Magnalium Alloy Housing & Metal Mechanical Control Wheels

The impact-resistant magnalium chassis delivers structural durability to protect internal optical alignments from mechanical shocks while maintaining a balanced weight in the hands. High-quality metal focusing wheels and diopter rings rotate with precise tactile resistance, allowing smooth, micro-fine focal adjustments in cold weather. Dry nitrogen gas filling prevents internal optical fogging during abrupt temperature changes, while the rubber armoring provides a secure, non-slip grip in wet conditions.

• High-quality metal central focus wheel and diopter ring offering durable mechanical control
• Watertight nitrogen-purged magnalium alloy housing built to withstand rough outdoor handling
• Retractable spectacle eyecups maintaining comfortable eye alignment for all observers
