The GPO Passion ED 10x32 Binoculars (Dark Brown Earth) deliver high-magnification mid-to-long-range observation in an ultralight roof-prism format. Built on a magnesium-alloy chassis with a compact micro-bridge design, this binocular combines 10x magnification with a 32 mm objective lens while keeping total carry weight down to 500 g. The optical path utilizes Extra-Low Dispersion (ED) glass elements, phase-corrected and dielectric-coated Schmidt-Pechan roof prisms, and GPObright™ fully multi-coated lenses to achieve 90% daylight light transmission. Nitrogen-purged and O-ring sealed, the housing is fully waterproof to 100 mbar (1 m submersion) and fogproof for reliable performance in adverse field conditions.

Key Features

• ED Optical System: Extra-Low Dispersion objective lenses paired with GPObright™ proprietary multi-coatings minimize chromatic aberration and provide 90% light transmission.
• Dielectric-Coated Schmidt-Pechan Prisms: Phase-corrected roof prisms deliver sharp resolution and accurate colour fidelity across the field of view.
• Rugged Magnesium Chassis: Micro-bridge architecture with rubber armouring and machined aluminium twist-up eyecups delivers single-handed grip stability at an overall length of ~118 mm.
• Weatherproof Construction: Nitrogen-filled housing provides internal fog resistance and waterproof submersion protection rated to 100 mbar.
• Tripod Adaptable: Integrated standard 1/4"-20 front socket allows direct mounting to tripod adapters for stationary glassing.

Who is the GPO Passion ED 10x32 for?

• Open-country stalkers and mountain hunters — need 10x magnification for resolving distant game details across open terrain while maintaining an ultralight 500 g carry weight that eliminates neck and chest fatigue during extended ascents.
• Daylight birdwatchers and hikers — benefit from this compact roof-prism binocular's 32 mm objective format and 2.2 m close-focus capability, offering pocketable carry without sacrificing the resolving reach of 10x magnification during daylight observation.
• Range shooters — require high-magnification target checking in a portable 500 g optic with a 105 m at 1,000 m field of view that mounts directly to standard 1/4"-20 tripod adapters without taking up the pack volume of full-size 42 mm glass.

Less suitable for: Deep twilight or dense canopy observation where the 3.2 mm exit pupil limits low-light brightness (an 8x42, 10x42, or 8x56 low-light hunting optic is better suited), tracking fast-moving targets in thick bush requiring a wider field of view than 105 m at 1,000 m (where an 8x32 optic is preferable), or prolonged stationary freehand scanning where a 500 g 10x optic exhibits hand tremor unless supported by a tripod or rest.
