With a new ergonomic design, the 8 x 30 Safari Pro is a pleasure to handle and view for long periods of time and perfect for sporting events, concerts and wildlife viewing. The 8 x 30 Safari Pro weighs only 18 ounces and is small and light enough to travel easily, yet powerful enough to put you in the middle of the action. It is designed like the versatile Steiner Military/Marine binocular, but with greater glare and UV blocking ability, nearly 100% UV-A and UV-B is blocked from your view for a comfortable, high contrast image. The profiled "wrap-around" eyecups block distracting side light and will keep you focused on your subject. For eyeglasses, the eyecups fold down for a full field of view. The 8 x 30 Safari Pro feature Steiner's convenient automatic focus that, once set for your eyes, gives you a sharp, clear view of everything from approximately 20 yards to infinity without further adjustment. Weight: 20 oz. Field of view: 360 feet @ 1000 yards. Eye relief: 11mm. Dimensions: 4.6" L x 6.8" W x 2.4" H. IP (Inter Pupil) Distance: 56-74mm.
