The Barska 20-60x60 Waterproof Colorado Spotting Scope is designed with multicoated optics in a rugged weather sealed housing. The wide zoom range makes this optical device ideal for hunting and bird watching, as well as spotting at the rifle range and even lunar observations. Use the 20x magnification to survey the entire landscape, then zoom to higher magnification and focus on fine details. Colorado spotting scopes use multicoated lenses and BK-7 Porro prisms to transmit bright, contrast-rich images with sharp detail even in low-light conditions. Weather seals, straight-body design and grooved zoom dial ensure this spotting scope will deliver a comfortable long-term viewing experience for years to come.
