Barska 's 10x50 Focus-Free Binocular gives you the power to instantly observe even the most elusive creature when there's no time to be fumbling with a focus knob. BK7 Porro prisms and blue-tinted anti-reflection fully coated optics increase light transmission and help to reduce glare, while preserving your ability to accurately see colors. An ultra-wide 70° apparent angle of view provides an exceptional panoramic view that, when coupled with the focus-free optical system, produces a truly immersive observational experience in the field, on the trail, or at the track. This version of the binocular comes complete with a case and strap in clamshell packaging.
