The GPO PASSION ED 10x32 Binoculars in Desert Sand (Model B322) provide high-magnification observation in a compact, lightweight roof-prism chassis designed for active outdoor use. Built with extra-low dispersion (ED) objective glass, dielectric-coated and phase-corrected Schmidt-Pechan roof prisms, and proprietary GPObright multi-coatings, this optical system delivers 90% daylight transmission to suppress chromatic aberration and ensure edge-to-edge clarity. Housed in a rubber-armoured magnesium-alloy micro-bridge body measuring 118 mm long by 118 mm wide, the unit weighs 500 g, making it suitable for all-day carry on a harness or lanyard without neck fatigue.

Key Features

• High-Transmission Optical System: Features 32 mm ED objective lenses and Schmidt-Pechan prisms with dielectric and phase coatings, achieving 90% daylight light transmission.
• Rugged Magnesium Chassis: Compact 118 mm x 118 mm magnesium-alloy micro-bridge design with protective rubber armouring and machined aluminium twist-up eyecups.
• All-Weather Protection: Fully waterproof to 100 mbar (1 m immersion depth) and nitrogen-purged to prevent internal lens fogging.
• Field of View and Eye Relief: Delivers a 105 m field of view at 1,000 m (6.0° angular field of view) with 15 mm eye relief and a 3.2 mm exit pupil.
• Mounting Interface: Integrated standard 1/4"-20 UNC front thread allows direct attachment to binocular tripod adapters for sustained glassing.

Who is the GPO PASSION ED 10x32 for?

• Lightweight mountain stalkers — relies on the 500 g total weight and compact 118 mm length of this compact hunting binocular to reduce pack bulk while maintaining 10x magnification for resolving game across distant ridgelines.
• Mobile backcountry hunters — benefits from the 90% light transmission and ED objective lenses of this 10x32 binocular, providing precise target identification across a 105 m field of view at 1,000 m during active foot patrols.
• Active birdwatchers and hikers — utilizes the 10x magnification paired with a manageable 32 mm objective lens to observe distant wildlife without the neck strain associated with heavier full-sized optics.

Less suitable for: Prolonged observation in deep dawn, dusk, or heavy forest canopy where the 3.2 mm exit pupil limits low-light visibility; hunters operating primarily in these lighting thresholds should step up to a larger 42 mm or 56 mm objective hunting binocular (such as an 8x42, 10x42, or 8x56) to achieve a wider 4.2 mm to 7 mm exit pupil. It is also limited for ultra-close macro inspection below its 2.2 m close-focus distance.
