The Barr & Stroud Sierra 8x42 helps you to better see birds, safari animals, and game while hunting. The lens pieces and prisms of the binoculars are multi-coated, so you get a contrast-rich and clear image with natural colors. You can view subjects in great detail, thanks to the 8x magnification. The eyepieces are easy to adjust to your eyesight using the little wheel. The rubber finish provides good grip and ensures that the binoculars can handle a bump or two.
