The Hawke Endurance ED 10x25 Compact Binocular in Green (Model 36111) is an ultra-portable roof-prism optical system engineered for handheld daylight glassing. Featuring Hawke System H5 optics with Extra-low Dispersion (ED) glass and fully multi-coated lenses, it delivers sharp contrast and true colour fidelity while eliminating chromatic aberration. The dual-hinge magnesium alloy chassis folds down to a compact 80 mm width, allowing the unit to slip easily into a jacket pocket or pack without adding unnecessary bulk.

Key Features

• System H5 ED Glass: Extra-low Dispersion glass elements minimise colour fringing across the entire 5.5° field of view.
• Phase-Corrected BAK-4 Prisms: High-resolution roof prisms maximise light transmission and edge-to-edge image clarity.
• Dual-Hinge Folding Design: Enables the barrels to fold tightly beneath the bridge, reducing overall carrying width to just 80 mm.
• All-Weather Reliability: Nitrogen-purged and O-ring sealed for 100% waterproof and fog-proof operation in wet or humid environments.
• Ergonomic Chassis: Magnesium alloy body finished with textured green rubber armouring and multi-stage twist-up eyecups with click stops.

Who is the Hawke Endurance ED 10x25 for?

• Day hikers and backpackers — benefits from an ultra-lightweight 315 g total carry weight and a dual-hinge folding design that packs down to 80 mm wide, keeping this compact binocular pocket-portable on extended trails.
• Hunters and stalkers — utilizes 10x magnification paired with a 25 mm objective lens for long-range target identification and scouting across open terrain without the bulk of full-sized field optics.
• Birdwatchers and wildlife observers — relies on a close focus distance of 2.0 m to observe nearby insects, flora, and resting birds with high-resolution, phase-corrected roof prisms.

Less suitable for: Low-light or twilight glassing, as the 2.5 mm exit pupil limits light gathering in heavy canopy or dawn/dusk conditions where full-sized 8x42 or 10x42 binoculars (providing 4.2 mm to 5.25 mm exit pupils) perform better; and rapid tracking of close-range, fast-moving subjects, where a wider 8x alternative provides a broader field of view than this model's 96 m @ 1,000 m profile.
