Steiner Navigator Autobright 7x50c with Compass

The Steiner Navigator Autobright 7×50c is built for serious maritime use, combining large 50 mm objectives with 7× magnification to deliver excellent visibility at sea under all lighting conditions. Its standout Autobright technology automatically adjusts brightness to match the environment—sunlight, reflections, twilight or even storms. Equipped with an HD‐stabilized, liquid‐damped compass with bearing mark and durable NBR-Longlife rubber armor, this binocular offers reliability, grip, and performance where it counts most.

ABOUT THE NAVIGATOR AUTOBRIGHT SERIES

The Navigator Autobright series refreshes Steiner’s marine line with intelligent optical enhancements and rugged construction. Features such as the “Open Bridge System” improve handling in rough seas; wave-patterned rubber armor ensures grip even when wet; high‐contrast optics and the integrated compass support safe, confident navigation. Built to endure the toughest marine conditions, the series combines precision, durability and usability in equal measure.

ABOUT THE MODEL (NAVIGATOR AUTOBRIGHT 7×50c)

The 7×50c model delivers a bright image thanks to its large 50 mm lens and robust optical system. With an exit pupil of 7.14 mm, light intensity 51.02, and a twilight factor of 18.7, it performs very well in low light at dawn, dusk or in reflectively bright environments. Field of view is 128 m @ 1000 m, with eye relief between 56-72 mm and diopter adjustment of ±5 dpt. Built for durability, it is waterproof to 5 m, filled with nitrogen against fogging, and designed to operate between −20 °C and +70 °C. At 1115 g, its dimensions (208×140.5×70 mm) are substantial, but matched with universal belt connection and a full suite of marine-friendly features such as lens protection flaps, rain cover, and carrying bag.
