Talk about bang-for-the-buck; the mainstream 8 power magnification with the very reasonable light transmission of 40-millimeter objectives, these binoculars possess multicoated optics for brighter, sharper, higher-contrasted viewing. They boast an exceptionally wide-angle AAoV of 65.4 degrees, which translates to a FOV spread of 429 feet at 1000 yards. The classic Porro prism design lays out better three-dimensional imaging with less light loss. The outdoor factor has not been ignored. Water resistant with rubber-covered aluminum housing, they are endowed with finger ridges and thumb indents. These binoculars want to make themselves easy to grip and hard to slip. Fold the rubber eyecups up, if you are not wearing eyeglasses; and fold them down if you are wearing eyeglasses or sunglasses, for the maximum field of view. Fold them back up for storage. These are all-around binoculars offering a moderately large size factor but well within the limits of a handheld steady view. Nonetheless, a tripod thread has been provided for long term viewing without undo fatigue.
