Compact and stable Steiner binoculars. With a 50 mm objective diameter and 7x magnification, the Commander provides a calm view even in rough seas. Thanks to Steiner’s unique Diamond Marine coating that uses a mix of rare fluoride and other minerals lenses produces a bright image with unequalled light transmission, clarity and contrast even in low light conditions. A hydrophobic front lens coating creates a lens surface that protects against dirt and water. Even rain and snow quickly form droplets that disappear from the field of view. Easy to hold with one hand, great field of view of 140 m at 1000 m, 2-way-valve-technology that prevents condensation inside the binoculars, NBR rubber armouring. Magnification: 7 x, prism type: Porro. Product Dimensions: 206 x 157 x 96 mm, weight: 1190 grams. Warranty: 30 years.
