Redfield's waterproof 8x42 Aurora binoculars are of roof prism design, with multi-coated lenses and BaK-4 prisms for exceptional brightness and clarity. Focusing is fast and easy with a positive-adjustment click diopter and center focus. You can also lock the binoculars on the focus you want by pulling the focus ring toward you, then unlock them by pushing the ring back in place.
