The 12-36x70 Gladiator Zoom Binocular from Barska is designed for long distance terrestrial and astronomical viewing. The variable magnification range of the binocular allows the viewer to scan a large field of view and then zoom in on the selected object for a closer and greater detailed look. A zoom thumb-lever for making quick and smooth magnifications is featured. Fold-down eyecups are incorporated into the eyepieces for comfort viewing with or without eyeglasses.
The 12-36x70 Gladiator Zoom binocular has BAK7 porro prisms and fully coated optics. Zoom magnification, large objective lens, shock-absorbing rubber armor, and an included tripod adaptor for a steady view, contribute to a binocular that's ideal for all outdoor activities and sporting events.
