The Nature DX Binoculars from Celestron are weather-sealed binoculars designed for close-to-midrange observations. These lightweight binoculars weigh less than 2 lb and are compact enough to fit in the side pocket of a daypack. In addition to the Nature DX binoculars' streamlined form factor, these fixed-magnification binoculars also feature fully multicoated optics and phase-corrected BAK-4 prisms that render enhanced clarity and color fidelity. The Nature DX binoculars have a nitrogen-filled polycarbonate housing that is built to withstand heavy rain and deliver fog-proof performance, making these Celestron binoculars ready for a wide range of outdoor glassing activities.
