Among the world’s greatest boating binoculars, the military-specification Fujinon 7×50 FMTRC-SX Polaris Binoculars with Compass transmit an incredible >95% of the light reaching the binoculars and have Fujinon’s EBC multi-coatings on every optical surface. They are also equipped (as are any Fujinon Polaris series binoculars) with flat-field, distortion-free eyepieces that accept optional filters and are ideal for astronomy applications. The 100% fog and waterproof 7×50 Polaris binoculars withstand drastic temperature and humidity changes with ease, have abundant eye reliefs for use with sunglasses in bright conditions, and are simply bright, high-resolution 7×50 boating binoculars. This version of the 7×50 Polaris binoculars have 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.
