The Hawke Nature-Trek 8x42 Monocular in Green (SKU 35220) is a compact, passive optical device engineered for mobile outdoor observation. Utilizing Hawke's System H2 optics, it features fully multi-coated (FMC) lenses and phase-corrected BAK-4 roof prisms to deliver high light transmission and contrast. Housed in a shock-resistant polycarbonate chassis wrapped in high-grip green rubber armour, the monocular is nitrogen-purged to provide complete waterproof and fog-proof performance across changing weather conditions. Weighing 315 g (11.1 oz) with an overall length of 143 mm, it provides single-handed optical scanning with an integrated 1/4"-20 UNC tripod mount for optional static mounting.

Key Features

  • System H2 Optical System: Features fully multi-coated lenses paired with high-resolution, phase-corrected BAK-4 roof prisms for clear edge-to-edge optical resolution.
  • Wide Field of View: Offers a linear field of view of 129 m at 1,000 m (7.4° angular FOV / 59° apparent FOV) for fast subject acquisition and landscape tracking.
  • Low-Light Optical Exit: Combines an 8x magnification with a 42 mm objective lens to yield a 5.3 mm exit pupil and 18 mm of eye relief via multi-position twist-up eyecups.
  • Rugged Weatherproof Build: Enclosed in a nitrogen-purged, waterproof, and fog-proof polycarbonate body with tethered lens caps and protective rubber armour.
  • Mounting Interface: Features a standard female 1/4"-20 UNC thread on the base for connection to tripods or window clamps.

Who is the Hawke Nature-Trek 8x42 Monocular for?

  • Lightweight bushwalkers and travellers — saves pack space and reduces carry fatigue by delivering a full 42 mm light-gathering objective lens in an optical unit that weighs just 315 g (11.1 oz).
  • Mobile hunters conducting reconnaissance — allows rapid single-hand glassing and wide-area terrain scanning with a 7.4° angular field of view and an 8x magnification that remains steady on the move.
  • Birdwatchers requiring a portable glass — resolves close-range plumage detail down to a minimum close focus distance of 2.0 m (6.6 ft) using a quick-adjust ocular focus dial.

Less suitable for: Long, static glassing sessions without eye fatigue, which require dual-tube binoculars, or extreme long-distance detail resolution where a higher-magnification 10x/12x full-size binocular or a dedicated spotting scope is required.
