The Hawke Nature-Trek 12x50 Green Binocular is a roof-prism optical device engineered for long-range terrestrial observation, open-country game spotting, and low-light field glassing. Built around Hawke's System H2 optics, it pairs 12x magnification with large 50 mm objective lenses, fully multi-coated (FMC) glass, and phase-corrected BAK-4 roof prisms to deliver sharp detail across wide landscapes. The shock-resistant polycarbonate chassis is nitrogen-purged, O-ring sealed, and wrapped in textured green rubber armour to provide waterproof and fog-proof reliability in demanding outdoor environments.

Key Features

• System H2 Optical System: Features phase-corrected BAK-4 roof prisms and fully multi-coated glass to maximise light transmission and edge-to-edge clarity.
• High-Magnification Range: Provides 12x magnification with an 82 m field of view at 1000 m (4.7° angle of view) for resolving distant subjects across open terrain.
• Rugged Weatherproof Body: Built with a lightweight top-hinge polycarbonate chassis that is nitrogen-purged and O-ring sealed for waterproof and fog-proof performance.
• Precise Ergonomics: Equipped with a large centre-focus knob operating through 2 turns from close focus to infinity, a right-eye dioptre adjuster, and multi-position twist-up eyecups.
• Tripod Adaptability: Features an integrated 1/4"-20 UNC front mounting thread to enable stable, hands-free viewing on standard tripod mounts.

Who is the Hawke Nature-Trek 12x50 Green for?

• Long-range open country deer and pest hunters — delivers 12x magnification paired with 50 mm objective lenses to resolve target detail and identify game across vast ridges and open valleys at an 82 m @ 1000 m field of view.
• Birdwatchers observing over large water bodies or open fields — provides high-powered 12x magnification alongside a 2.5 m close focus distance, allowing birders to switch smoothly between distant wetlands and near-distance shoreline subjects.
• Hunters conducting low-light dawn and dusk glassing sessions — utilises 50 mm light-gathering objectives with fully multi-coated optics to maintain visibility during transitional dawn and dusk light levels.

Less suitable for: Ultralight all-day trekking where weight is constrained, making binoculars under 650 g preferable over this 829 g model; prolonged handheld viewing where 12x magnification hand-shake fatigue requires a tripod or chest support; or hunting in heavily timbered canopies and thick bush where an 8x42 or 8x56 binocular with a larger exit pupil provides superior low-light transmission.
