The 12x56 Nature DX Binoculars from Celestron are a general purpose set of binoculars featuring a fully multicoated optical path and a weather-resistant housing. By combining multi-layer coated lenses with high-transmission BAK4 prism glass, Nature DX binoculars produce bright images that are rich with contrast and sharpness. These 12x binoculars from the Nature DX series have a minimum focus distance of 10 ft. A nitrogen-filled housing provides fogproof and waterproof performance and non-slip rubber armoring help maintain a secure grip in wet conditions or while wearing gloves. Additionally, twist-up eyecups and 16mm eye relief will create a comfortable viewing distance for almost any viewer.
