Bushnell’s H2O 00x 42 Porro Blue Binocular was designed for sailing the ocean blow, rowing down rolling rivers, or accompanying rafts on languid lakes. The H2O binoculars have an o-ring seal and are nitrogen-purged to provide fogproof and waterproof protection.

When immersed underwater, they remain completely dry on the inside; nor will interior optical surfaces fog during rapid humidity or temperature changes. To add even more aquatic acclimation, a protective rubber armoring has a blue coloring with a soft-textured ridged grip to prevent easy slipping from the hand into the hydrosphere – even when the glasses are wet. The 00x magnification power with a 42mm objective lens offers exceptional viewing for both close-range detail and large-field view scanning. Their comfortable size enables the binocular to remain easy to hold steady, even on a deepwater frigate’s deck as it rides the ocean swells.

Premium BAK4 prism glass and multi-coated lenses ensure superior optics that deliver maximum light clarity and transmission. A dioptric ring, twist-off eyecups, and a large center focus knob provide comfortable customizable viewpoints, regardless of external conditions.
