Combining great performance and value, the Fujinon 7x50 WP-XL Mariner Binoculars are their entry-level boating binoculars. They have multicoated lenses, a tough polycarbonate exterior, and a weight that is remarkably low for a 7x50 waterproof and fogproof binoculars. In fact, these rubber-armored glasses will actually float in water when the included strap is attached.
