Zeiss Terra ED Binoculars 8x42

Optically, they retain the exceptional elements that are the hallmarks of the Terra ED, including compact Schmidt-Pechan roof prisms, SCHOTT extra-low dispersion (ED) glass, and proprietary multicoatings. These complementary technologies and elements work together to produce an immersive observational experience that presents clear and bright views with accurate color representation and virtually zero distortion across the entire field of view. Adding to the binoculars' usability is a short 5.25-foot close-focus distance that gives them the ability to resolve feathers or leaves in fine detail.

The comfortable ergonomic chassis is made of a fiberglass-reinforced polycarbonate to help reduce weight without sacrificing strength, while adding impact and temperature resistance. Being resistant to temperature changes not only ensures that the housing will remain a constant temperature in cold and wet conditions, but also that it will not experience the expansion and contraction common in metal chassis that can cause the optical elements to move out of alignment over time and hinder the binoculars' ability to achieve sharp focus. The chassis is covered in a black rubber armoring that helps protect them from drops and impacts, and it provides a slip-resistant grip.
