Celestron's new Nature DX binoculars are the perfect companions for nature lovers. These affordable but powerful binoculars have all the important features, such as fully multi-coated optics and BaK-4 prisms, without being out of reach of beginners or amateurs in terms of price. You can take the Nature-DX binoculars out into the wild with a clear conscience. Even the largest models are still very transportable and lightweight. Even bad weather is no problem, the waterproof housing is filled with nitrogen and is therefore fog-proof.
