Specifically designed to aid in the detection of game hidden by foliage and difficult light conditions, the Steiner Predator Pro features the same game sensing Penetrator lens coating system that has been successfully utilized in Steiner's rifle scopes. The Predator's "Penetrator" coating adds contrast to woodland colors making detection of game against a wooded or camouflaged background easier to see for the human eye. The Predator Pro employs the military design and construction that has made Steiner binoculars legendary in the optics industry. Shockproof to 11G's and guaranteed against fogging or leakage, the Predator Pro can withstand the toughest use and most adverse weather conditions. Steiner's automatic focus system creates a depth of field from approximately 20 yards to infinite distance that is sharp and clear without the need to refocus. With a long eye relief of 20mm and wrap-around eyecups, the Predator Pro provides eyeglass wearers with full field of vision and blocks out distracting side light. The darker forest green rubber armoring on the Predator Pro conceals the viewer from his quarry and ensures a slip-proof grip in all conditions. Weight: 18 oz. Field of view: 360 feet @ 1000 yards.
