Carson Stinger 10x25mm Compact Binocular Matte Brass. Although they are considered compact they still quite capable of packing a punch. The Carson Sig 10x25 Binocular features fully multi-coated lenses and BK-7 prisms housed in a rugged exterior. These binoculars are nitrogen-filled and O-ring sealed for complete water and fog proofness. With 10x magnification the Carson Stinger Binoculars are quite powerful.
