Bushnell's 10x28 Off-Trail Binoculars are an ideal companion for your pack or bag when you need power without bulk. To offset the smaller objectives, they provide BAK4 roof prisms and anti-reflection multi-coated optics that produce clear and crisp high-contrast images with true color rendition. The combination of right-eye dioptric correction and a large focusing knob ensures sharply defined images, and to give you an immersive observational experience the apparent angle of view approaches wide-angle, so you'll be sure to see the whole scene in front of you. Twist-up eyecups make the Off-Trail binoculars comfortable to use with or without eyewear.
