The GPO Passion ED 8x42 Orange (Model B344) is a roof-prism hunting binocular engineered for woodland tracking, wildlife observation, and general-purpose field scouting. Built around Schmidt-Pechan roof prisms and extra-low dispersion (ED) glass elements, it utilizes proprietary GPObright fully multi-coated optics to maximize resolution while minimizing chromatic aberration. Featuring a full magnesium micro-bridge and chassis finished in textured rubber armour, the optic pairs a wide 426 ft field of view at 1,000 yards with a high-visibility orange exterior designed for field retention in dense brush.

Key Features

• Optical System: Extra-low dispersion (ED) objective lenses with phase-correcting and dielectric-coated Schmidt-Pechan prisms for color accuracy.
• Chassis Construction: Full magnesium housing with aluminium twist-up eyecups and a textured rubber exterior finish.
• Environmental Protection: Nitrogen-purged housing delivers complete waterproof and fogproof performance in damp or dusty conditions.
• High-Visibility Housing: Safety-orange body enhances visibility to prevent gear loss when resting optics on the ground or in thick scrub.
• Tripod Adaptability: Features an integrated 1/4"-20 threaded socket to mount directly onto standard binocular tripod adapters.

Who is the GPO Passion ED 8x42 Orange for?

• Hunters in dense scrub — Requires a roof-prism hunting binocular with a 426 ft at 1,000 yd field of view and a safety-orange chassis to rapidly track game in heavy brush without losing the optic when set down.
• Bushwalkers and wildlife observers — Requires an all-day carry optic weighing 26.0 oz with an 8x magnification and 5.25 mm exit pupil to maintain steady handheld tracking and twilight viewing on mobile trails.

Less suitable for: Specialized extreme low-light or night glassing beyond the light capture of a 5.25 mm exit pupil (where larger 8x56 binoculars fit better), or open-country scouting beyond woodland distances (where 10x or 12x binoculars or a dedicated spotting scope are recommended).
