Celestron Nature DX 10x42 Black BinocularsNature DX Black 10x42 Binoculars are identical to the green ones except for the color of the rubber armoring. They have an amazing feature set for their price. They are lightweight, smaller than many of their competitors, and are the first to offer phase corrected BaK 4 prisms at this price level. Add to that a 6. 5' close focus, wide field of view, and fully multi coated lenses and you have a beginner's dream binocular.
