RSPB Harrier X 8x32 Binoculars

The RSPB Harrier X 8x32 (product ID 49568977355059) delivers 8x magnification through a 32mm objective lens. That combination gives you a wide 145m field of view at 1000m and an exit pupil of 4mm well suited to daytime birdwatching and tracking fast-moving birds. At just 524g it sits comfortably in hand for long sessions.

The optics are built around ED glass and phase-corrected BAK-4 prisms with super high reflective dielectric coatings. Lenses are fully multi-coated throughout. Together these technologies all but eliminate colour fringing and deliver a bright crystal-clear image with strong contrast and resolution right to the edge of the field.

The magnesium alloy body is wrapped in shock-resistant rubber armour with thumb-holds for grip. It is fully waterproof and nitrogen-filled to prevent internal fogging. Twist-down eyecups with three settings make it practical for spectacle wearers. The ultra-close focus distance lets you observe butterflies and insects in sharp detail.

Ten-year manufacturer warranty backs the build quality. ED glass, dielectric prism coatings, a compact magnesium body and a 145m field of view make this a serious birdwatching tool at a mid-range size.

The 8x32 format gives a 4mm exit pupil good for daylight use. ED glass reduces chromatic aberration so colours stay true and edges stay sharp. Phase-corrected BAK-4 prisms correct the light wave phase shift that occurs in roof prism designs. Super high reflective dielectric coatings on the prisms push light transmission well above standard silver coatings. Fully multi-coated lenses reduce surface reflections across all glass elements. The result is a bright high-contrast image with minimal colour fringing.

The chassis is magnesium alloy strong and light. External rubber armour absorbs shock and improves grip. ED glass elements sit within a fully multi-coated optical path. BAK-4 prisms carry phase correction and super high reflective dielectric coatings. Nitrogen fill replaces internal air to prevent fogging.

Use a blower brush before wiping lenses with a clean microfibre cloth. Store in a case away from moisture and extreme heat. Check the hinge tension and eyecup action regularly. The 10-year warranty requires correct use and storage avoid dropping or exposing to chemicals.
