Specifically engineered and built to withstand the rigors of life on the water, Steiner's 7x50 C Navigator Pro Binocular with Compass produce bright and clear images, reduce the disorientation commonly experienced when using optics in marine environments, and includes a precise navigation tool. An integrated compass features bearing marks that don't interfere with the field of view, and is stabilized to increase visibility during rolling seas. The compass is backlit for easy viewing in all lighting conditions and the brightness adjustment is easily made, even while holding the binocular one-handed. Its large objectives gives the binocular high light-transmittance for enhanced low-light performance, and a large exit pupil which helps to reduce the effects of rough and rolling seas - which can cause disorientation during observation. The porro prism optical design combined with the fully multicoated optics provides high-contrast images with true color representation and long depth of field.
