The 7-21x40 Colorado Reverse Porro Zoom Binocular from Barska is a compact and cost-effective handheld optic useful for a wide range of outdoor activities. The variable 7-21x magnification is ideal for intermediate to long-range bird watching, hunting, and sightseeing. A reverse Porro prism design and fully coated optics transmit detail-rich resolution with edge to edge clarity and excellent low light performance. The rubber armored housing helps protect your optics from moisture and light shock. For the nature enthusiast on a tight budget, the ergonomic design and complementing features of Colorado series binoculars deliver a comfortable user-experience and high quality images.
