The Alpen Chisos 10x50 ED Binoculars provide unmatched optical performance with exceptional detail and true-to-life color accuracy, making them ideal for birdwatchers, hikers, and outdoor adventurers. Designed for high-performance optics, these binoculars feature Extra-Low Dispersion (ED) glass, phase-coated BaK4 prisms, and fully multi-coated lenses, which work together to deliver sharp contrast, vivid colors, and bright, clear images—even in low-light conditions. With a 50mm aperture, they capture ample light, allowing you to observe your surroundings clearly, even during twilight or in dimmer environments.
Built for the toughest conditions, the Alpen Chisos 10x50 ED Binoculars are waterproof and fogproof, nitrogen-purged to protect against moisture and internal fogging. The magnesium housing makes these binoculars lightweight yet rugged, able to withstand the rigors of extended outdoor use. The close-focus range (2m-2.5m) allows for detailed viewing, especially for birdwatchers who need to spot intricate details at close range.
Comfort and stability are prioritized with a textured grip and a roof prism design for steady handling during extended viewing sessions. The twist-up eyecups provide a customizable fit for both eyeglass and non-eyeglass users. With a lifetime warranty (with registration), the Alpen Chisos 10x50 ED Binoculars offer reliability and performance for years to come.
