Expert Binocular Group

Swift 8.5x44mm BWCF Audubon Waterproof Binoculars 820 is Swift's premium choice in porro prism birding binoculars. An 8.5x power binocular is a great compromise between the classic debate of magnification, size and exit pupil diameter. You'll have an exit pupil diameter of 5.1mm, great enough for viewing in nearly all birding situations, and a very wide 8.2? angle of view for an 8.5 magnification binocular.
