The 10x42 NatureView Roof Binocular from Bushnell has a lead-free optical path that is fully multicoated for enhanced contrast and image clarity. This model of the NatureView series binocular uses a roof prism design, which enables a more streamlined form factor compared to Porro prism designs. The binocular weighs less than 1.5 lbs and features a rubber-armored weather-sealed housing, making it well-suited for day hikes and other recreational activities. Twist-up eyecups and 15mm eye relief permit a comfortable viewing distance even while wearing eyeglasses. A 62° apparent viewing angle provides immersive views, making the 10x42 NatureView a well-equipped binocular for almost any mid-range observation.
