The black ZEISS Optics 10x42 Terra ED Binoculars feature 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 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 wide field of view The 60 degrees apparent angle of view also helps to minimize the visible hand shake common in higher-power binocularsThe comfortable ergonomic chassis is made of a fiberglass-reinforced polycarbonate to help reduce weight without sacrificing strength It also adds impact and temperature resistance Being resistant to temperature changes ensures the housing remains a constant temperature - even in cold and wet conditions 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 to protect them from drops and impacts and provides a slip-resistant grip
