The most powerful binocular in the 42 mm Ultravid class. The redesigned eyecups allow for a very comfortable positioning of the eye. This becomes very apparent with the improved image steadiness while viewing over great distances. New ergonomics for relaxed handling : the formed thumb supports on the rear of the 50 mm and 42 mm HD models ensure that the binoculars fit in your hands without slipping. The large central focusing device enables relaxed natural handling.
