Combining great performance and value, the Fujinon 7x50 WP-XL Mariner Binocular is their entry-level boating binocular. It has multicoated lenses, a tough polycarbonate exterior, and a weight which is remarkably low for a 7x50 waterproof & fogproof optic. In fact, this rubber armored unit will actually float in water when the included strap is attached.
