Steiner Navigator Features The Steiner Navigator delivers 7x magnification through a 50mm objective lens striking a balance between brightness and portability for marine and outdoor use. Auto focus technology keeps the image sharp without manual adjustment which matters when tracking a moving vessel or animal from an unstable position. A wide 419 foot field of view at 1 000 yards helps users locate and track subjects quickly while a 66 foot close focus distance adds versatility for nearer objects. The 7.14mm exit pupil provides a bright image even in lower light conditions common at dawn dusk or on open water giving the Navigator an edge for glassing in the hours when game and traffic on the water are both hardest to spot. Waterproof construction protects the internal optics from spray rain and submersion making the Navigator dependable in marine environments where lesser binoculars would fail. A 20.2mm eye relief accommodates users wearing glasses or sunglasses without sacrificing the full field of view so the image stays complete and comfortable through long stretches of use. The diopter adjustment range of plus or minus 5 allows each eye to be individually tuned for sharp focus correcting for differences between a user s left and right eye rather than forcing a single compromise setting. The CR1225 battery powers the auto focus system for extended use keeping the Navigator ready to deploy without the delay of manual focusing wheels. At 30 ounces and measuring 5.5 inches long 2.87 inches high and 8.2 inches wide the Steiner Navigator is compact enough to carry comfortably on deck or in a pack making it a practical everyday optic for anyone who spends long hours on the water or on the trail and needs glass they can trust without fuss.
