Tech Talk
Objective Lens: The diameter from the objective or front lens. The larger the objective lens, the harder light that enters the binocular, along with 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 scheduled through the width in feet or meters in the area visible at 1000 yards or meters. An extensive angle binocular includes a wide field of view and it is better for following action. Generally, the greater the magnification, the narrower the field of view.

Roof Prism System: In roof prism binoculars the prisms overlap closely, allowing the goal lenses to line up directly using the eyepiece. The result is a slim, stream-lined shape through which the lenses and prisms are in a straight line.
The Bushnell® Powerview® Series of binoculars offers you compact, streamlined designs for bright, crisp views of wherever you're exploring.
