The Barska 10x50 Focus Free Binocular has a fixed focus design making instant viewing available when there's no time to be fumbling with a focus knob. A Porro design with BAK7 glass and multicoated optics create a viewing experience of clarity and high contrast. The blue tinted lenses help reduce glare. A very wide apparent angle of view of 69.9deg. provides an exceptional panoramic view. This optic is ideal as an all around long-distance scope for sporting events and races, nature walks, wildlife observation or any situation where a fixed focus binocular could enhance the visual experience.
