Celestron TrailSeeker 8x42 ED Binoculars - Compact Birdwatching Binoculars with ED Objective Lenses, Broadband Multi-Coated Optics, BaK4 Roof Prism

PREMIUM ED OBJECTIVE LENSES: Extra-Low Dispersion (ED) glass virtually eliminates chromatic aberration or color fringing, a visual defect common in binoculars. You'll enjoy razor-sharp images with outstanding, true-to-life color. PHASE-COATED BaK-4 PRISMS FOR BRIGHTER VIEWS: The prisms inside TrailSeeker ED feature quality BaK-4 glass with phase coatings that maximize light transmission to your eye. The result is bright, highly detailed views—even in low light conditions. DURABLE, WATERPROOF BODY: A rubber-armored, polycarbonate housing protects your binoculars from damage and stands up to the toughest weather conditions. They're also fully waterproof and nitrogen purged to prevent internal fogging of the lenses. TWIST-UP EYECUPS FOR QUICK ADJUSTMENT: Large focus knobs make for easy and precise focusing. Twist-up eyecups allow you to customize the binocular's eye relief to obtain a full field of view with or without eyeglasses. FIELD-WORTHY ACCESSORIES INCLUDED: TrailSeeker ED comes complete with a comfortable carry harness, a deluxe padded neck strap, a single piece eyepiece cover, tetherable objective covers, a durable padded carrying case, and more.
