Amongst the world's greatest boating binoculars, the military-specification Fujinon 7x50 FMTRC-SX Polaris Binocular with Compass transmits an incredible >95% of the light reaching the binocular, and has Fujinon's EBC multicoatings upon every optical surface. It is also equipped (as is any Fujinon Polaris series binocular) with flat-field, distortion-free eyepieces that accept optional filters and are ideal for astronomy applications.
The 100% fogproof and waterproof 7x50 Polaris withstands drastic temperature and humidity changes with ease, has abundant eye relief for use with sunglasses in bright conditions, and is simply the brightest, highest-resolution 7x50 boating binocular money can buy. This version of the 7x50 Polaris has both a rubber armored exterior and an internal compass with rangefinding reticle. While the compass is electronically controlled for rapid response to bearing changes, illumination is by a natural daylight-gathering window. At night, you will need the optional external compass illuminator.
