Hawke Endurance ED 10x25 Monocular

• 10× Magnification for Detailed Distance Observation: The 10× magnification provides greater image scale than the 8×25 model for more detailed subject identification at distance — relevant for birding and wildlife observation where the additional resolving power of 10× supports accurate identification of fine detail. At 152 g and 35 mm wide × 105 mm high, the dimensions are virtually identical to the 8×25 monocular, making it equally compact and pocketable.
• Extra-Low Dispersion Glass with Phase Corrected BAK-4 Roof Prism: The Extra-Low Dispersion (ED) glass reduces chromatic aberration and colour fringing at 10× magnification — where colour correction is more important than at lower powers as the higher image scale amplifies any optical shortcomings. The phase corrected BAK-4 roof prism and fully multi-coated lenses maintain resolution and contrast across the full aperture.
• Practical Field of View at 10×: The field of view of 96 metres at 1,000 metres and apparent field of view of 55° provide a practical observation width for birding and wildlife observation at the higher magnification — supporting target acquisition and tracking without the extremely narrow view of some 10× compact optics. The close focus distance of 5 metres covers typical field observation distances.
• Ultralight and Pocket-Sized — 152g: At just 152 g and 35 mm wide × 105 mm high, the 10×25 monocular is one of the lightest 10× optics in the Hawke lineup. The compact monocular format eliminates the hinge mechanism, interpupillary adjustment, and second optical tube of a binocular design — reducing size and weight to the minimum possible for single-eye use at this specification level.
• Waterproof and Fogproof with Twist-Up Eyecup and Lanyard: The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber exterior. The twist-up eyecup with position stops and 13mm of eye relief accommodate both bare-eyed and eyeglass-wearing users. The supplied lanyard allows the monocular to be worn around the neck or wrist for immediate access. Stay-on objective lens cover remains attached during use.

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. The series covers 8×25 and 10×25 configurations, both featuring nitrogen purging, waterproof and fogproof construction, twist-up eyecups with position stops, stay-on lens covers, and a supplied carry case and lanyard.

The two models share identical dimensions and near-identical weight, differing only in magnification and the resulting field of view and exit pupil. The 8×25 provides a wider field of view and brighter image, while the 10×25 delivers greater image scale for more detailed subject identification at distance.

About the Model (Hawke Endurance ED 10x25 Monocular)

The Hawke Endurance ED 10x25 Monocular is designed for birders, travellers, and nature observers who want the higher magnification of 10× in the same ultracompact monocular format as the 8×25. The 10× magnification with a 25mm objective lens delivers a field of view of 96 metres at 1,000 metres and an exit pupil of 2.5mm suited to bright outdoor observation conditions. At 152 g and 35 mm wide × 105 mm high, it is one of the lightest and most compact 10× optics available at this specification level.

The ED glass reduces chromatic aberration and colour fringing at 10×, while the phase corrected BAK-4 roof prism and fully multi-coated lenses maintain resolution and contrast across the field. The close focus distance of 5 metres covers typical field observation distances. The 13mm of eye relief and twist-up eyecup with position stops accommodate both bare-eyed and eyeglass-wearing users.

The body is nitrogen purged, waterproof, and fogproof with a high-grip rubber exterior. The supplied lanyard allows the monocular to be worn around the neck or wrist. Stay-on objective lens cover remains attached during use. No tripod mounting thread is included.
