Field of View
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 1,000 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.

Some binoculars are O-ring sealed and nitrogen purged for total waterproof and fogproof protection. These models can withstand complete immersion in water and stay dry inside. The interior optical surfaces won’t fog due to rapid temperature change or humidity.
