Discover the world in vivid detail with the BRITEC CR Binoculars—engineered to elevate every outdoor adventure. Our patented Optisan® off-hinge focusing system brings razor-sharp clarity faster than ever: simply slide open, fine-tune with a smooth turn, and lock onto your subject with pinpoint precision. Wrapped in a Swissamotec 98™ armored housing, these binoculars shrug off bumps, drops, and the elements, yet remain featherlight at just 210 g. Whether you’re birdwatching at dawn, tracking wildlife on safari, or cheering from the stadium, the BRITEC CR slips effortlessly into your jacket pocket or clutch, ready to capture every moment in brilliant color.

Peer through premium high-index BaK4 prisms and enjoy unmatched contrast, while fully multi-coated green optics bathe your view in rich, natural hues. Even low-light scenes sparkle with life. Twist-up eyecups and generous 16 mm eye relief ensure comfortable, full-frame viewing—perfect for eyeglass wearers. When rain or mist rolls in, rely on IPX7 waterproof protection to keep your optics dry and fog-free. And with a wide 118 m field of view at 1,000 m, you’ll never miss a fleeting glimpse of action at the edge of your vision.

Designed for explorers who demand more, the BRITEC CR combines cutting-edge innovation with intuitive handling. Center-focus mechanics paired with a unique off-hinge diopter adjustment make peering into distant landscapes or pinpointing fast-moving subjects effortless. Ready for any environment, these binoculars operate smoothly from –10 °C to 50 °C and can even survive brief submersion thanks to their robust sealing. When not in use, stash them in the included water-resistant pouch, sling on the neck strap, and head out—adventure is calling.
