Steiner Navigator Pro 7x50
Autofocus system
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.
Makrolon housing
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'.
