Hawke Endurance 8x56

• 56mm Objective Lens with 7mm Exit Pupil — Maximum Low-Light Capability: The 56mm objective lens at 8× magnification produces an exit pupil of 7mm — the largest available in the Hawke binocular lineup and one of the largest in any binocular in this magnification class. The 7mm exit pupil matches the maximum dilation of the human pupil in low-light conditions, delivering a bright, fully utilised image at dawn and dusk when game is most active. This makes the 8×56 the dedicated low-light hunting configuration in the Endurance binocular range.
• Exceptional 23mm Eye Relief for Maximum Comfort: The 23mm of eye relief is among the longest available on any binocular in this class — providing safe, comfortable clearance from the eyepiece for both bare-eyed and eyeglass-wearing users. The twist-up eyecups with position stops allow consistent eye positioning at the correct distance for the full field of view, regardless of whether glasses are worn.
• Phase Corrected BAK-4 Roof Prisms with Fully Multi-Coated Lenses: The phase corrected BAK-4 roof prisms eliminate the phase shift inherent to roof prism designs, maintaining resolution and contrast across the full aperture. Combined with fully multi-coated lenses, the optical system delivers a clear, well-resolved image for target identification in the demanding low-light conditions where the 56mm objective is most often used.
• Wide Field of View for a 56mm Binocular: The field of view of 117 metres at 1,000 metres and apparent field of view of 54° provide a practical scanning width for hunting use — supporting target location and tracking across terrain at the low-light periods of dawn and dusk when the 56mm format is most relevant.
• Waterproof and Fogproof Construction with Tripod Thread: The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber-coated exterior. A built-in ¼"-20 UNC tripod mounting thread enables use on a tripod or binocular mount — useful for extended stationary observation during dawn and dusk glassing sessions where the weight of a 56mm binocular makes held use more tiring. Stay-on objective lens covers remain attached during use.

About the Endurance Binocular Series

The Hawke Endurance binocular series is built on the H5 optical system, designed for hunters, birders, and nature observers who require reliable, high-quality optical performance in a field-ready package at an accessible price point. The series covers a broad range of configurations — from compact ED glass models through to the large-objective 8×56 dedicated low-light hunting configuration — all built on phase-corrected BAK-4 roof prisms with fully multi-coated lenses, nitrogen purging, and waterproof construction.

Within the Endurance range, models featuring Extra-Low Dispersion (ED) glass are designated as the Endurance ED sub-series. The Endurance 8×56 is a non-ED configuration within the broader Endurance lineup, using fully multi-coated lenses and phase corrected BAK-4 roof prisms without the additional chromatic aberration correction of ED glass elements — appropriate for a model where the primary design priority is maximum light gathering through the large 56mm objective rather than chromatic aberration control at high contrast.

About the Model (Hawke Endurance 8x56 — Green)

The Hawke Endurance 8x56 is a dedicated low-light hunting binocular designed for hunters who require maximum image brightness during the critical dawn and dusk periods when game activity peaks. The 56mm objective lens at 8× magnification produces a 7mm exit pupil — matching the maximum dilation of the human pupil in low-light conditions and delivering the brightest image possible through an 8× binocular. No other configuration in the Endurance lineup matches the light-gathering capability of the 8×56 in low-light field conditions.

The phase corrected BAK-4 roof prisms and fully multi-coated lenses maintain resolution and contrast for clear target identification at the low-light distances and angles encountered during twilight hunting. The field of view of 117 metres at 1,000 metres and apparent field of view of 54° provide a practical scanning width for locating and tracking game. The close focus distance of 2.5 metres accommodates occasional close-range use when needed.

The 23mm of eye relief — the longest in the Endurance binocular lineup — provides generous, comfortable clearance from the eyepiece for both bare-eyed and eyeglass-wearing users, supported by twist-up eyecups with position stops. The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber exterior. The built-in ¼"-20 UNC tripod mounting thread supports tripod use during extended glassing sessions. Stay-on objective lens covers remain attached during use. Weight is 1,005 g and dimensions are 128–144 mm wide × 163 mm high.
