Steiner 7x50 Navigator Pro Binoculars

Specifically engineered and built to withstand the rigors of life on the water - Steiner's 7x50 Navigator Pro Binoculars produce bright and clear images and reduce the disorientation commonly experienced when using optics in marine environments Their large objectives give the binoculars 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 fieldEach 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'
