The ProSport 8x40 Camo Binocular (Camouflage, Clamshell Packaging) from Simmons has been engineered to deliver a very expansive apparent field of view of 65.5°. This wide angle binocular can scan 430 feet at 1000 yards serving the user with the ability to quite literally broaden their horizon. A normative exit pupil of 5 millimeters with eye relief of 12.3 millimeters delivers a comfortable viewing experience. BAK7 multi coated lenses afford brighter, sharper, more contrasted images. Built for the more adventurous - waterproofing, fogproofing and durable rubber armoring allow use in rough and tumble environments. Not to say that they can't be used at the tennis match.
