Tasco TS825B

Tasco's black 10x25 Sierra Compact Binocular is an ideal instrument that brings the action up-close without taking up a lot of room or adding excessive weight. Anti-reflection multicoated optics maximize the light coming into the 25mm objectives while minimizing light loss. Complementing the optical performance is a water and fogproof housing that features a textured rubber armoring with finger grooves to provide protection from impacts and to give it a slip-resistant grip.
