Hawke Frontier EDX 10x25 Compact Binoculars

The Hawke Frontier EDX 10x25 (product ID 55900223046007) is a 10x magnification compact binocular with a 25mm objective lens. That pairing gives you a field of view of 116m at 1000m solid for a pocket-sized glass. The double-hinge body folds down small enough to fit in a jacket pocket without sacrificing optical quality. This is a serious compact built for real outdoor use.

Hawke uses ED (extra-low dispersion) glass in the Frontier EDX which cuts chromatic aberration and keeps colour accurate across the image. The BAK-4 roof prisms are dielectric coated and phase corrected which pushes light transmission higher than standard silver coatings. The fully multi-coated optical system works across every air-to-glass surface. The result is a bright sharp image with accurate colour rendition even in tricky light.

The chassis is magnesium alloy light but stiff. Nitrogen purging makes it waterproof and fogproof so internal fogging is not a problem in cold or wet conditions. Eye relief is 16mm which works reasonably well for spectacle wearers. The central focus wheel and compact form factor make it comfortable to use for extended periods.

Lifetime manufacturer warranty backs the Frontier EDX. ED glass, dielectric prisms, magnesium build and nitrogen sealing in a pocket-sized body this is a well-specified compact binocular at this size.

The 10x25 pairing gives a 2.5mm exit pupil which is adequate in good daylight but limits low-light performance. ED glass reduces chromatic aberration so colour fringing at high-contrast edges is minimised. BAK-4 roof prisms with dielectric mirror coatings and phase correction deliver higher light transmission than standard silver-coated prisms. Fully multi-coated lenses reduce surface reflections across every element. The 116m field of view at 1000m is solid for a 10x compact. Nitrogen purging prevents internal fogging in cold or wet conditions.

The chassis is magnesium alloy stiff and light. The body is rubber armoured for grip and protection. Optics use ED extra-low dispersion glass elements. Prisms are BAK-4 glass with dielectric mirror coatings and phase correction. The sealed body is nitrogen purged to keep moisture and condensation out.

Use a blower or soft brush before wiping lenses with a microfibre cloth. Store in the case when not in use and keep the strap attached to avoid drops. Store in a dry place away from heat. Check the hinge and eyecups regularly for wear. The lifetime warranty depends on avoiding physical damage and misuse.
