Fujinon 7x50 WPC-XL Mariner Binoculars are entry-level boating binoculars equipped with a compass. They have multi-coated lenses, a tough polycarbonate exterior, and a weight that is remarkably low for a 7x50 waterproof and fogproof optic. In fact, these rubber-armored binoculars will actually float in water when the included strap is attached. The compass' LED illumination and activation button are on the left objective, away from the compass itself, so that electrical interference is avoided.
