Specifically engineered and built to withstand the rigors of life on the water, Steiner's 7x50 Navigator Pro Binocular produce bright and clear images and reduce the disorientation commonly experienced when using optics in marine environments. Its large objectives gives the binocular high light-transmittance for enhanced low-light performance, and a large exit pupil which helps to reduce the effects of rough and rolling seas - which can cause disorientation during observation. The porro prism optical design combined with the fully multicoated optics provides high-contrast images with true color representation and long depth of field.
Each ocular is individually focused for precise customization for each user and will maintain that focus from 65' to infinity - so users can concentrate on the views, not re-focusing. To hold up to the elements, the housing is made of temperature and impact-resistant Makrolon polycarbonate. NBR rubber armoring on the exterior is resistant to oil, acid, and weathering, as well as providing a slip-resistant grip in cold or wet conditions. The optical tubes are nitrogen-filled for fogproof performance, and the Navigator Pro is waterproof to 16'.
