Designed to Brunton's stringent Eterna specifications, this Full Size binocular in Mossy Oak camouflage is designed for users who want big glass in a rugged, ergonomic mid-sized frame. This 11x Eterna binocular--a great choice for viewing over long distances--is lightweight and nimble, with a durable alloy frame that weighs a mere 28 ounces. More importantly, the Eterna delivers razor-sharp images with the help of the 45mm lenses made of BaK-4 prism glass--made from a higher quality glass (barium crown) that helps produce brighter images and high edge-to-edge sharpness--and the trio of coating processes, including state-of-the-art phase coating, AL reflective coating, and Emerald Fire full multi-coating. Even discounting all the bells and whistles, the Eterna Full-Size is a tough customer, with an ergonomic body armor that's both waterproof and fog-proof.
Specifications range from a 305-foot field of view at 1,000 yards to a 19.5mm long eye relief to a 4.1mm exit pupil. The focus system, meanwhile, sharpens images as close as 8 feet. Additional features include a multi-step eye relief system that's eyeglass-compatible, tripod/monopod compatibility, and neoprene Bino Glove lens covers. The Eterna Full-Size 11x measures 6 by 5.1 by 2.2 inches (WxHxD) and is backed by a limited lifetime warranty.

Tech Talk
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 8x32 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.
