ZEISS Terra ED 10x42 Grey Binoculars (524204-9907-000)

The gray 2017 edition of Zeiss Optics' 10x42 Terra ED Binocular features a redesigned ergonomic chassis that makes holding them more comfortable, especially during long glassing sessions. 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 the proprietary multi-coatings. 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 wide field of view. The 60° apparent angle of view also helps to minimize the visible hand-shake common in higher-power binoculars. 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, even in cold and wet conditions, but 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 preventing the binocular's ability to achieve sharp focus. The chassis is covered in a gray rubber armoring that helps to protect it from drops and impacts, and provides a slip-resistant grip.
