Offering an impressive collection of features at a nice price point, the Brunton Echo Mid-Size binocular excels at mid- to long-distance viewing. The lightweight 8x power binocular features a polymer frame that weighs a mere 20 ounces, along with ergonomic body armor that protects the frame from damage. The Echo's high-clarity 32mm objective lenses, meanwhile, are 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 are shielded by an Emerald Fire full multi-coating. Add in Brunton's twist-up eye relief system--which is both comfortable and eyeglass compatible--and a waterproof and fog-proof housing and you have a great binocular for almost any outdoor application. Specifications range from a 394-foot field of view at 1,000 yards to a 16mm long eye relief to a 4mm exit pupil. The focus system, meanwhile, sharpens images as close as 6 feet. Additional features include tripod/monopod compatibility, protective lens covers, and a comfortable neck strap and carrying case. The Echo Mid-Size measures 4.8 by 4.8 by 2.2 inches (WxHxD) and is backed by a five-year 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.
