What is the maximum effective ranging distance on non-reflective game like deer and pigs for the GPO Rangeguide 2800 10x50?

While the laser can reach up to 2,800 metres on highly reflective targets under ideal conditions, the effective ranging distance for non-reflective game like deer and pigs is up to 700 metres. For semi-reflective targets such as trees and foliage, you can expect reliable readings up to 1,000 metres.

How does the 50mm objective lens perform during dawn and dusk low-light conditions in the Australian bush?

The 10x50 configuration paired with double-HD laminated glass and proprietary GPObright multi-coatings delivers up to 92% light transmission. This makes it exceptional for dawn and dusk glassing in low-light environments, significantly outperforming smaller 32mm or 42mm optics when game is active at first and last light.

Does the GPO Rangeguide 2800 10x50 require any specialized Australian electrical safety certifications or AC charging adapters?

No AC charging or mains connection is required. The unit operates exclusively on a single replaceable CR2 3V lithium battery, meaning no SAA certification or 230-240V charging adapters are needed. It complies with standard Australian laser safety requirements as an eye-safe Class 1 laser device.

Are there any compatible accessories available from XHunter that pair well with the weight and size of these binoculars?

At roughly 1,000 to 1,050 grams, these binoculars benefit greatly from a supportive chest carry system. We recommend pairing the BX750 with the GPO Bino Harness Pro to evenly distribute weight across your shoulders during long-distance spot-and-stalk hunts in the outback.

Laser Rangefinder Binocular - GPO BX750

The GPO Rangeguide 2800 10x50 is a laser rangefinding binocular designed to merge high-transmission observation optics with long-range distance measurement. Built around a magnesium alloy micro-bridge chassis, it pairs 10x magnification with 50 mm Double-HD objective lenses and Schmidt-Pechan prisms coated with GPObright™ multi-coatings, achieving up to 92% light transmission. Its integrated Class 1 eye-safe laser delivers line-of-sight and angle-compensated True Range calculations out to 2,800 m on reflective targets, with readings displayed on a customisable red OLED screen with 9 brightness settings and ambient auto-adjustment.

Key Features

Double-HD 50 mm Optical System: Delivers a 5.0 mm exit pupil and 110 m field of view at 1,000 m, treated with PASSIONdrop™ hydrophobic coatings for moisture resistance.
Multi-Target Laser Ranging: Ranging envelope covers reflective targets up to 2,800 m, semi-reflective brush up to 1,000 m, and non-reflective game out to 700 m.
Hyperscan Ranging Engine: Scans continuously at 3 to 4 pings per second with a 0.25-second response time for tracking moving game.
Environmental Readouts: Measures direct distance, True Range angle compensation, incline/decline angles, and ambient field temperature in either yards or metres.
Weatherproof Magnesium Chassis: Rubber-armoured, nitrogen-purged housing offering 100 mbar waterproof protection and an overall weight of 1,000 g to 1,050 g.
Independent CR2 Power: Operates on a single 3V CR2 lithium battery without requiring external cords or mains charging systems.

Who is the GPO Rangeguide 2800 10x50 for?

Open-country mountain spot-and-stalk hunters — scanning broad terrain using a 110 m at 1,000 m field of view while acquiring distance and true horizontal angle calculations instantly out to a 2,800 m maximum ranging distance with this laser rangefinding binocular.
Dawn and dusk low-light big game hunters — relying on the 50 mm Double-HD objective lenses and 5.0 mm exit pupil of this laser rangefinding binocular to maintain image brightness and target identification during extreme low-light transitions.
Long-range precision rifle shooters — tracking targets rapidly using Hyperscan mode at 3 to 4 pings per second with line-of-sight and angle data across targets ranging out to 2,800 m.

Less suitable for: Ultralight backcountry hunters who require a sub-800 g pack weight (where a compact 32 mm class rangefinding binocular is better suited), or long-range shooters requiring onboard custom ballistic curve programming and Bluetooth app synching (who are better served by a dedicated connected ballistic rangefinder unit).
