The German Precision Optics (GPO) Rangeguide 2800 8x50 (Model BX740) integrates an eye-safe Class 1 laser rangefinder into a high-transmission Double HD glass optical chassis. Built with 50 mm objective lenses and GPObright multi-coatings achieving up to 92% light transmission, it delivers a large 6.3 mm exit pupil for twilight observation alongside fast distance and angle calculations out to 2,800 m.

Key Features

• Long-Range Laser Engine: Measures reflective targets up to 2,800 m, tree cover up to 1,000 m, and game animals (deer) up to 700 m with a minimum range of 3.0 m.
• True Range Ballistic Calculations: Provides Line of Sight (LOS) and angle-compensated horizontal distance readouts, plus real-time inclination angle and ambient temperature displays in Celsius or Fahrenheit.
• Hyperscan Ranging Mode: Emits 3 to 4 distance readings per second with Best/Last target priority logic displayed on an adjustable red OLED screen with 9 manual brightness levels and an auto-adjust mode.
• Rugged Magnesium Chassis: Features a magnesium alloy micro-bridge body with protective rubber armour, nitrogen purging, and a 100 mbar waterproof rating.
• Low-Light Optical System: Combines Double HD glass with GPObright multi-coatings and PASSIONdrop hydrophobic external lens coatings.

Who is the GPO Rangeguide 2800 8x50 for?

• Dawn and dusk big game hunters — 50 mm objective lenses combined with an 8x magnification yield a large 6.3 mm exit pupil and up to 92% light transmission, allowing this laser rangefinding binocular to resolve targets in extreme low-light conditions at first and last light.
• Deer stalkers operating in low-light environments — 8x magnification and a wide 115 m field of view at 1,000 m allow fast target scanning in timber, coupled with an integrated rangefinder that detects deer-sized game out to 700 m.
• Long-range rifle shooters — 2,800 m maximum reflective target capability provides instant true horizontal distance and angle readouts on a red OLED display to feed external ballistic charts.

Less suitable for: Lightweight alpine stalking or ultralight pack hunting requiring a lower carry weight penalty, where the 1,008 g to 1,050 g weight of these 50 mm optics is better replaced by compact 32 mm or 42 mm rangefinding binoculars.
