The GPO Rangeguide 2800 8x32 is a compact laser rangefinding binocular that combines 8x optical magnification and a 32 mm objective lens with an integrated rangefinder. Designed to eliminate the bulk of traditional 42 mm or 50 mm electro-optics, it measures distances to reflective targets out to 2,800 metres (approx. 3,062 yards) and soft game targets out to 700 metres. Built around a lightweight magnesium housing with rubber armouring, the unit weighs approximately 700 g (839 g with supplied straps and covers) and measures 137 mm in length, 124 mm in width, and 56 mm in height.

Key Features

• Integrated Laser Rangefinder: Delivers true line-of-sight (LOS) and angle-compensated horizontal distance readings with a fast 0.25-second response time (4 scans per second).
• Environmental Sensors: Displays on-board ambient temperature, air pressure, and humidity readouts alongside target range data.
• Red OLED Display: Provides 9 manual brightness levels plus an automatic ambient brightness adjustment mode.
• HD Optical System: Fully multi-coated lenses featuring GPObright coatings deliver edge-to-edge clarity and a 135 m field of view at 1,000 m.
• Weatherproof Construction: Nitrogen-purged and waterproof up to a 100 mbar rating to prevent internal fogging and moisture ingress.
• Power Supply: Operates on a single user-replaceable 3V CR2 lithium battery.

Who is the GPO Rangeguide 2800 8x32 for?

• Mobile backcountry and mountain hunters — requires a lightweight 700 g laser rangefinding binocular that reduces carry fatigue over steep terrain while providing reflective distance measurements out to 2,800 m.
• Archery hunters — benefits from a close-ranging minimum distance of 6 m and integrated angle-compensated horizontal distance calculation within a compact 137 mm long chassis.
• Long-range shooters — needs fast 0.25-second ranging out to 700 m on deer-sized targets with on-board atmospheric readouts for temperature and air pressure.

Less suitable for: Dedicated low-light dusk, dawn, or spotlighting scenarios where the 4.0 mm exit pupil limits light transmission; larger 8x56 or 10x42/8x50 rangefinding binoculars with larger exit pupils are better suited to maximise twilight light gathering.
