GPO Passion ED 10x42 Binoculars in Black

The GPO Passion ED 10x42 binoculars (product 47032381964595) deliver 10x magnification through a 42mm objective lens. That combination pulls in serious detail at distance while the 42mm aperture gathers enough light for solid performance in low light. Field of view at 1000m is 114m which is competitive for a 10x42. The exit pupil works out at 4.2mm practical for dawn and dusk use.

These use ED (Extra-Low Dispersion) glass with state-of-the-art multi-coatings across all optical surfaces. ED glass cuts chromatic aberration sharply meaning colours stay true and edges stay clean. Light transmission is exceptional and the image is bright and high-contrast from centre to edge. One reviewer noted chromatic aberration was almost impossible to detect under most conditions.

The entire housing is magnesium and weighs 725g. Dimensions are H55 x W127 x L138mm. The rubberised exterior adds grip and durability and the top-hinge design with narrow bridge sits comfortably in the hand. The well-positioned focus wheel gives quick precise control. These are waterproof and fogproof.

A 10-year manufacturer warranty backs the build. ED glass, magnesium chassis, multi-coated optics and a 114m field of view at 1000m make this a strong performer. Includes a carry case and strap.

The 10x42 format gives a 4.2mm exit pupil bright enough for dawn and dusk use. ED glass reduces chromatic aberration so colour fringing at high-contrast edges is minimal. State-of-the-art multi-coatings on all surfaces push light transmission to its practical maximum giving bright high-contrast images. The roof prism design keeps the body slim and compact. Magnesium housing holds everything rigid so optical alignment stays true under field conditions.

The entire chassis is magnesium alloy keeping weight to 725g. A rubberised exterior coating covers the body for grip and impact resistance. Optical elements use ED extra-low dispersion glass with multi-coatings applied to all air-to-glass surfaces. The roof prism assembly sits within the sealed nitrogen-filled body.

Use a soft brush or blower before wiping lenses with a microfibre cloth. Store in the supplied case when not in use. Keep the hinge and eyecups free of grit. Avoid dropping or knocking the body. The 10-year warranty depends on normal careful use and proper storage.
