The Steiner Navigator 7x30c Marine Binoculars with Compass are engineered to deliver professional-grade, shake-free optical performance on turbulent seas. Featuring a modern open-bridge system and a textured, water-repellent rubber exterior, they guarantee a secure, one-handed grip even in freezing rain or heavy swell. These premium marine electronics are encased in an 11G shockproof Makrolon polycarbonate body, pressurized with nitrogen to permanently eliminate internal fogging. Navigation is completely seamless thanks to an integrated, fluid-dampened HD compass that illuminates instantly under low-light conditions on the water. Additionally, the specialized Steiner Auto-Focus system lets you lock onto objects from 20 meters away out to an endless horizon without needing constant visual adjustments.
