Savor every detail of nature's panorama through massive 42 mm objective lenses treated with fully multi-coated green optics and phase-corrected Bak-4 prisms. Light transmission is maximized, dispersion and distortion are minimized, and your view stays razor-sharp from corner to corner. The generous 16.1 mm eye relief and twist-up eyecups make long observation sessions supremely comfortable, whether you wear glasses or not.
Built to handle any environment, the BRITEC R is nitrogen-purged and sealed to IPX7 standards, so it remains fogproof and submersion-proof down to one meter. Its Swissamotec 98™ rubber-armored body stands up to knocks, drops and bumps, giving you the confidence to explore rugged trails, misty wetlands or rain-soaked forests without worry.
Focus in on nearby subjects with an astonishing 4 m close-focus distance—perfect for studying butterflies, flowers and other small treasures. A broad 106 m field of view at 1,000 m (6.1°) ensures you never lose sight of soaring raptors or darting deer. The center-focus wheel is smooth, precise and easy to turn, so you can lock in crisp detail in the blink of an eye.
When adventure calls, the BRITEC R answers with lightweight portability and uncompromised optics. Slip on the included neoprene neck strap, stow your binoculars in the water-resistant pouch, and head out—every spectacular scene is now within reach.
