Enjoy reliable performance from this pair of durable Bushnell Explorer 10×28 binoculars while hunting, fishing or hiking. Offering a 10x magnification and 28mm objective lens size, they feature multi-coated lenses to reduce light loss and glare due to reflection, and BaK-4 roof prisms–made from a higher quality glass (barium crown) that helps produce brighter images and high edge-to-edge sharpness. They’re also built tough, with a rubber-armored housing that’s O-ring sealed and nitrogen purged for 100 percent waterproof and fogproof dependability.

Rubber armor provides multiple benefits. It helps protect the binocular from the bumps and scratches that come with day-to-day use. It provides a comfortable gripping surface for making them easier to hold on to. It’s easy to wipe clean after a tough day in the field. And it suppresses noise if the binocular bumps aluminum or other non-rubber surfaces, which might otherwise spook wildlife.

In addition to being waterproof and fogproof, Bushnell’s Explorer binoculars offer a 10x magnification, 28mm objective lens, and multi-coated lenses to reduce light and glare.

Tech Talk:
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, streamlined shape in which the lenses and prisms are in a straight line. Roof prism binoculars are less bulky and more rugged than an equivalent porro model.

Exit Pupil–Refers to the size of the circle of light visible at the eyepiece of a binocular. The larger the exit pupil, the brighter the image. To determine the size, divide the objective lens diameter by the power (an 8×32 model has an exit pupil of 4mm).

Eye Relief–The distance a binocular can be held away from the eye and still present the full field-of-view. Extended or long eye relief reduces eyestrain and is ideal for eyeglass wearers.

Field-of-View (F.O.V.)–The side-to-side measurement of the circular viewing field or subject area, 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.
