【VERSATILE, ALL-AROUND BINOCULARS】These premium binoculars are a great choice for birdwatching, nature observation, the trail, stadium, arena, or anywhere you want a close-up view of the action without sacrificing brightness or detail.
【BaK-4 PRISMS FOR OPTIMAL VIEWING EXPERIENCE】The prisms inside Nature DX ED feature quality BaK-4 glass with phase coatings applied to maximize light transmission and enhance bright, highly detailed images – especially in low light conditions.
【DURABLE, WEATHER-RESISTANT BODY】 A rubber-armored, polycarbonate housing protects your binoculars from damage and stands up to even the toughest weather conditions! They're also fully waterproof & nitrogen purged to prevent internal fogging of the lenses.
【UNBEATABLE WARRANTY AND CUSTOMER SUPPORT】Buy with confidence from Celestron, a leading binocular and telescope brand, based in California since 1960. Your purchase is backed by a Limited Lifetime warranty and unlimited access to technical support team.
