With powerful magnification and large objective lenses, the Barska 12x60 X-Trail Binoculars deliver a bright image and reveal distant details. Fully anti-reflective coated lenses and a Porro prism of BK7 glass form a clean view with lots of contrast, even at times with lower light, and 60mm objectives yield a 5mm exit pupil for comfortable viewing. Rubber armoring with a textured surface provide a protective nonslip grip and added protection for the housing and internal optics.
