The 15x80 Senator features excellent brilliance for long distance observation of birds and wildlife, especially in low light conditions. Originally designed for military and border patrol applications, the 15x80 Senator binocular is built tough with a completely armored waterproof body that's military specification and tough enough to withstand tundra-like conditions. A tripod mount is included, but the 15x80 Senator is light enough to be easily handheld. Also available with Steiner's no stabilized compass system and range reticle for fast determination of distance and direction.
