Witnessing beauty in its natural state doesn"t have to come with an unnatural price tag. Case in point, the NatureView® binoculars. Available in a variety of different models, including two new configurations for 2004, they"re affordable and loaded with features. Designed specifically for serious birders and naturalists, the ultra close-focus capabilities get you intimate with the details without getting pecked in the head. BaK-4 porro prisms on select models yield brighter images and better edge sharpness. Extended eye relief reduces eyestrain for eyeglass wearers during long observation periods. They"re perfect for the budding nature observer.
