GPO Passion 10x56 Binoculars

The GPO Passion 10x56 Binoculars (product ID 47032383996211) pair 10x magnification with a large 56mm objective lens. That combination pulls in serious amounts of light and gives you a 114m field of view at 1000m making these a serious tool for low-light observation at dusk and dawn.

At the heart of these binoculars is a custom Abbe-König prism system a design that delivers superior light transmission compared to standard roof prisms. The lenses carry fully multi-coated GPO bright lens coatings for maximum brightness and colour accuracy. Note: the spec sheet confirms no ED glass is used here.

The body is built from magnesium durable and robust and weighs 1275g. Dimensions are H67 x W158 x L192mm. These are waterproof and the eye relief is a generous 20mm which works well for spectacle wearers. They are not nitrogen filled.

Why buy these? The Abbe-König prism gives you light transmission that most binoculars at this price simply cannot match. A 10-year manufacturer warranty backs the build. One verified buyer rated them above Zeiss binoculars at nearly twice the price. For low-light wildlife watching these are hard to beat.

The 10x56 pairing gives a 5.6mm exit pupil large enough for low-light use at dusk and dawn. The Abbe-König prism is a roof prism design that avoids the phase-shift losses common in Schmidt-Pechan prisms meaning more light reaches your eye. GPO bright lens coatings are applied to all air-to-glass surfaces. No ED glass is used but the prism design and coatings compensate well. The 20mm eye relief makes these comfortable for spectacle wearers.

The chassis is magnesium durable and significantly lighter than steel. The exterior carries rubber armouring for grip and impact resistance. Lenses are fully multi-coated optical glass. The Abbe-König prism is a high-transmission glass prism system. No ED glass is used in this model.

Brush dust off lenses before wiping always use a clean microfibre cloth. Store in the carry case when not in use and keep them dry. Check the hinge tension and eyecups regularly. The 10-year warranty depends on normal careful use avoid dropping or immersing beyond the waterproof rating.
