The Hawke Nature-Trek Compact Spotting Scope 13–39x56 (Model 55211) is a straight-viewing optical instrument engineered for field mobility and mid-range observation. Featuring Hawke's System H2 optics with fully multi-coated (FMC) lenses and BAK-4 Porro prisms, this compact spotting scope delivers variable 13x to 39x magnification while maintaining a lightweight footprint of 944 g and an overall length of 243 mm. Encased in protective rubber armour, the housing is nitrogen-purged to provide complete waterproof and fog-proof reliability in damp or dusty Australian environments. It integrates a smooth barrel-focusing mechanism, an 18 mm eye relief with a twist-up eyecup for glasses wearers, and a standard 1/4"-20 UNC tripod mounting thread for steady field deployment.

Key Features

• Compact Optical System: Employs BAK-4 Porro prisms and fully multi-coated glass to maximise light transmission across a 13–39x zoom range.
• Field-Ready Form Factor: Measures 243 mm in length and weighs 944 g, enabling easy pack storage and off-hand or window-mounted operation.
• Barrel Focusing Mechanism: Enables precise optical adjustments across the entire focal range down to a 4.0 m close focus distance.
• Weatherproof Construction: Nitrogen-purged and rubber-armoured body prevents internal fogging and ingress from water and dust.
• Mounting Versatility: Features a standard 1/4"-20 UNC thread, supplied with a window mount and a stay-on neoprene protective cover.

Who is the Hawke Nature-Trek Compact Spotting Scope 13-39x56 for?

• Mobile spot-and-stalk hunters — requires a compact straight spotting scope weighing just 944 g (33.3 oz) to glass distant game across broken terrain without adding the bulk of full-sized optics to an all-day pack.
• Backcountry backpackers — benefits from a shortened 243 mm (9.6 in) overall length that fits inside standard gear compartments while delivering up to 39x magnification for long-distance terrain evaluation.
• Target shooters checking hits at short-to-mid ranges — utilises the precise 13–39x zoom range and 4.0 m (13.1 ft) close focus capability to resolve bullet groupings on target faces directly from the bench.

Less suitable for: Low-light twilight or dawn basecamp glassing, where the 56 mm objective lens contracts the exit pupil to 1.4 mm at 39x magnification; low-light long-distance observation is better served by a heavier, full-sized 80 mm+ tripod-mounted spotting scope.
