Using its BAK4 Porro prisms' design, Bushnell's 10x50 Legacy WP Binoculars stand out by delivering greater depth perception when compared to their Roof prism counterparts. Despite the wider distance between the tubes, they offer a comfortable non-slip grip (thanks to the rubber covering) and an easy-to-reach center focusing wheel. To equalize the image sharpness in both eyes, they also have a diopter ring on the right tube. With their wide 50mm objective lenses with fully multi-coated optics, the binoculars collect more light and deliver crisp and bright images in most lighting conditions including twilight. They can even be used for stargazing and observing the moon. To enable you to take them anywhere, the binoculars' optic housing is made completely waterproof, is nitrogen-filled for fogproofing, and provides adaptability to tripods for removing image jitter and making long observations easy.
