Hawke Endurance 8x56 Binoculars

The Hawke Endurance 8x56 (product ID 47032431378739) is a large-objective binocular built for low light conditions. The 56mm objective lens paired with 8x magnification produces a 7mm exit pupil one of the largest available in a standard binocular pushing serious amounts of light to your eye at dawn and dusk.

Optics are built around BAK-4 roof prisms with phase correction and Hawke's System H5 fully multi-coated lenses. These coatings maximise light transmission and deliver high-contrast images with accurate colour. No ED glass is used but the fully multi-coated setup still produces crisp results across the field.

The body is rubber armoured for grip and weighs 1005g. It is nitrogen filled and fully waterproof making it fogproof in cold or wet conditions. Twist-up eyecups with position stops suit both spectacle wearers and bare-eyed users. Eye relief is a generous 23mm. Close focus sits at 2.5m.

With a 117m field of view at 1000m and effortless central focusing these binoculars are built for low light wildlife watching and dawn or dusk observation. A lifetime manufacturer warranty backs the build quality.

The 8x56 pairing produces a 7mm exit pupil calculated by dividing 56 by 8 which is near the maximum the human eye can use in darkness. BAK-4 glass prisms in a roof configuration with phase correction reduce light scatter at the prism junction improving resolution and contrast. Fully multi-coated lenses on all surfaces reduce reflection losses at each glass-to-air interface. Nitrogen filling prevents moisture condensing on internal glass surfaces. The 23mm eye relief and 6.7-degree field of view make this a practical low light observation tool.

The body is rubber armoured for grip and weather resistance. The chassis material is not explicitly stated in the reference data. Prisms are BAK-4 glass with phase correction coatings. Lenses use fully multi-coated standard optical glass. The sealed construction is nitrogen filled for internal moisture protection.

Wipe lenses with a microfibre cloth after use. Remove dust with a blower before wiping. Store in the case when not in use and keep dry. Check the hinge tension and eyecup action periodically. The lifetime warranty requires the binoculars to be maintained correctly and not subjected to misuse or physical damage.
