Steiner Navigator Features The Steiner Navigator pairs 7x magnification with a 50mm objective to pull in ample light for low-light conditions on the water or in the field while its auto focus design keeps the image sharp from 66 ft to infinity without turning a focus wheel. The 7.14mm exit pupil delivers a bright image even as ambient light fades near dawn or dusk a real advantage for anyone glassing from a moving boat or a treestand. A plus or minus 5 diopter adjustment allows the optic to be dialed in for individual eyesight and the CR1225 battery powering the auto focus system keeps the unit compact. Measuring 4.2 inches long 2.75 inches high and 8.2 inches wide the Navigator keeps a manageable footprint for a 50mm binocular. Built to Steiner s reputation for rugged field-ready optics the Navigator is designed to stand up to repeated use in marine and outdoor environments. Its 26.6 oz weight balances optical performance with a build light enough for hours of handheld glassing. The wide 419 ft field of view at 1000 yards makes it easier to track moving subjects whether that is a vessel on the horizon or game moving through brush. Hunters anglers and anyone who spends long hours behind glass will find the Navigator a dependable optic for sale at GrabAGun.
