The 8x50 Foresta DCF Binocular from Vixen Optics has an open-bridge design and a fully multicoated optical path with BAK4 prism glass. This combination of features, in addition to a water-sealed housing, delivers the reliability and ergonomic handling that nature enthusiasts need during a long day in the field. Complementing the crisp images transmitted by the Foresta DCF optics, a remarkable 22mm eye relief and large 6.3mm exit pupil make this 8x50 model ready for almost any viewing task. For those long-duration sessions during migration season, a built-in tripod adapter mounting socket gives birders the option of stabilized hands-free glassing with a tripod. The Foresta DCF comes with a carrying case, flip-down objective covers, rainguard, and Vixen's lifetime warranty.
