The Coleman compact 10-21x23 binocular offers a powerful adjustable zoom in a compact, lightweight body. Porro prisms allow for high quality resolution through increased light transmission. With fully coated objective lenses, light is fed into the porro prisms and then through BK7 prisms for a perfectly round exit pupil and clear unvignetted images. An easily adjustable zoom ranges from 10x to21x and is easily operated with the slide of a finger. Along with the focusing wheel these binoculars are easy to zoom and focus. Added eye relief and twist up rubber eyecups are optimal for glasses wearers and reduces eye strain to make sure you are close to the action for the maximum amount of time. Included are a soft case and lens caps, which allow these versatile compact binoculars to be taken anywhere with ease.
