Spend enough time on the water, and your equipment will spend some time in it. That's why Bushnell had the foresight to build the H20 series of binoculars, which are O-ring-sealed and nitrogen-purged to complete lock out moisture should you spill water on the housing, take your binoculars overboard, or simply run into foul weather along the way. The H20 binoculars feature rubber armoring with textured pads to give you a sturdy grip in slippery situations. More significantly, the binoculars' multicoated optics and premium-quality BaK-4 prisms maximize light transmission and image clarity, so you can enjoy a clear view of the Orcas in the distance or the fast-approaching coastline. You'll quickly see how a little planning on Bushnell's part goes a long way in magnifying your adventures on or around the water. Other features include twist-up eyecups, a large center focus knob for easy, precise adjustments, and a long eye relief.

  Objective Lens: The diameter of the objective or front lens. The larger the objective lens, the more light that enters the binocular, and the brighter the image.

  Field of View (F.O.V.): The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide angle binocular features a wide field of view and is better for following action. Generally, the higher the magnification, the narrower the field of view.

  Roof Prism System: In roof prism binoculars the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, stream-lined shape in which the lenses and prisms are in a straight line.
