Hawke Endurance ED 8x25 Monocular

• Extra-Low Dispersion Glass with Phase Corrected BAK-4 Roof Prism: The Endurance ED 8x25 Monocular uses Extra-Low Dispersion (ED) glass to reduce chromatic aberration and colour fringing, combined with a phase corrected BAK-4 roof prism and fully multi-coated lenses for high resolution and contrast. The H5 optical specification provides a clean, well-resolved image for the intended range of monocular use cases — bird identification, wildlife observation, and general field use.
• Compact and Ultralight — 150g and Pocket-Sized: At just 150 g and 35 mm wide × 105 mm high, the Endurance ED 8x25 Monocular is exceptionally compact and lightweight — small enough to carry in a shirt pocket and light enough to go unnoticed in any kit. The monocular format provides a single optical tube without the interpupillary adjustment and hinge mechanism of a binocular, reducing both size and weight while retaining full optical functionality for single-eye use.
• 8× Magnification with Wide Field of View: The 8× magnification with a 25mm objective lens delivers a field of view of 119 metres at 1,000 metres and an apparent field of view of 54° — providing a practical observation width for target acquisition and tracking at the distances relevant to general field use, wildlife observation, and sporting events.
• Twist-Up Eyecup with Position Stops and Stay-On Lens Cover: The twist-up eyecup with position stops accommodates both bare-eyed and eyeglass-wearing users at 13mm of eye relief, with defined click positions for consistent eye distance setting. The stay-on objective lens cover remains attached to the monocular body during use, preventing loss in the field.
• Waterproof and Fogproof Construction: The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber-coated exterior — providing full field-ready weatherproofing in a genuinely pocket-sized monocular format. The close focus distance of 5 metres covers typical field observation distances.

About the Endurance ED Monocular Series

The Hawke Endurance ED Monocular series is the monocular range within Hawke's H5 optical system, built on the same Extra-Low Dispersion (ED) glass, phase corrected BAK-4 roof prisms, and fully multi-coated lenses as the Endurance ED binocular lineup. Monoculars provide a single optical tube for one-eye observation — significantly more compact and lightweight than an equivalent binocular — making them well suited to supplementary field use, travel, sporting events, birding, and any application where a full binocular would be too bulky to carry consistently.

The Endurance ED Monocular series covers 8×25 and 10×25 configurations, both in green. All models feature the full H5 optical specification in a pocket-sized, waterproof, and fogproof package with twist-up eyecups, stay-on lens covers, and a supplied carry case and lanyard.

About the Model (Hawke Endurance ED 8x25 Monocular)

The Hawke Endurance ED 8x25 Monocular is a compact, ultralight monocular designed for birders, travellers, wildlife observers, and outdoor enthusiasts who want H5 ED glass optical quality in the most pocketable possible format. At 150 g and 35 mm wide × 105 mm high, it is one of the lightest optics in the Hawke lineup — smaller and lighter than even the compact 25mm Endurance ED binocular — and can be carried without any practical impact on kit weight or volume.

The 8× magnification with a 25mm objective lens delivers a field of view of 119 metres at 1,000 metres — matching the Endurance ED Compact 8×25 binocular — with an exit pupil of 3.1mm suited to bright outdoor conditions. The ED glass reduces chromatic aberration and colour fringing, while the phase corrected BAK-4 roof prism and fully multi-coated lenses maintain resolution and contrast for a clean, detailed image.

The twist-up eyecup with position stops and 13mm of eye relief accommodate both bare-eyed and eyeglass-wearing users. The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber exterior. The stay-on objective lens cover remains attached during use. The supplied lanyard allows the monocular to be worn around the neck or wrist for immediate access. No tripod mounting thread is included.
