The Bushnell H2O 10×42 is a waterproof, fogproof binocular built for wet days: boating, rainy hikes and birding in bad weather. Its BaK-4 prisms and fully multi-coated lenses give a bright, clear view in daylight, and the rubber armour and textured grip suit wet hands. Its limits are just as clear: the view softens at dusk, the lens caps loosen with use, and at about 25 ounces it is not the lightest 10×42 you can carry. If your outings happen in all weather, it earns its place. If you mostly watch at dawn and dusk, look at a brighter glass instead.
