The Hawke Endurance ED 10x50 Green (Model: 36209) is a roof-prism hunting binocular engineered for high-resolution, low-light observation. Built around the System H5 optical design, it integrates Extra-Low Dispersion (ED) glass elements with fully multi-coated lenses and phase-corrected BAK-4 roof prisms with silver mirror coatings. This configuration maximizes light transmission while suppressing chromatic aberration. Housed in a textured, rubber-armoured polycarbonate top-hinge chassis, the optical chambers are nitrogen-purged and fully sealed against water and internal fogging. It delivers a 5.0 mm exit pupil and 17 mm to 18 mm of eye relief, accommodating eyeglass wearers via multi-position twist-up eyecups. A standard 1/4"-20 UNC tripod mounting socket is integrated directly into the central hinge for static glassing setups.
Key Features
- System H5 ED Optics: Extra-Low Dispersion glass combined with phase-corrected BAK-4 roof prisms eliminates colour fringing and enhances image clarity.
- Low-Light Aperture: Large 50 mm objective lenses paired with a 5.0 mm exit pupil ensure bright target identification during dawn, dusk, and beneath dense forest canopies.
- Durable Waterproof Chassis: Nitrogen-purged, rubber-armoured polycarbonate construction provides impact resistance and prevents internal fogging.
- Tripod Compatibility: Built-in 1/4"-20 UNC threading allows direct attachment to standard tripod adapters for stable, extended viewing sessions.

Who is the Hawke Endurance ED 10x50 for?
- Dawn and dusk spot-and-stalk hunters — Delivers a generous 5.0 mm exit pupil via 50 mm objective lenses, providing this roof-prism binocular with superior low-light transmission compared to standard 42 mm configurations when identifying game at twilight.
- Long-range wildlife observers — Combines 10x magnification with ED glass optics and a 2.5 m close focus threshold, allowing observers to resolve fine feather and coat details across open fields and moderate distances without chromatic fringing.
- Casual stargazers and astronomers — Features 50 mm light-gathering objectives and a 6.0° angular field of view, enabling broad-field constellation and lunar scanning in a hand-held 794 g chassis.
Less suitable for: Macro botanical and insect observation requiring a close focus under 2.5 m (where dedicated close-focus compact optics are better suited), total darkness operations requiring digital or thermal night vision devices, and prolonged fast-paced mountain trekking where weight exceeding 800 g prompts the selection of compact 8x32 or 8x42 binoculars.
