Compare Steiner Senator (20x80) Binocular to Steiner Military/Marine (10x50) Binocular

Whether you're glassing to the next ridge, down city streets, or in any other situation when you want to "let your optics do the walking." The 20-x Senator puts you at an effective distance of less than 100 yards from one mile-distant wildlife or other objects. Many hunters and outdoorsmen are discovering these high power binoculars are easy to use, give them a better view and offer a lot more comfort during extended use than spotting scopes. And the 80-mm objective lenses, combined with Steiner's legendary optics, deliver far superior low-light performance. Don't let their light weight they're 30% lighter than look-alike competitors fool you. These binoculars were originally developed for military and border patrol applications and are mil. spec. tough: totally waterproof, shock resistant, and rubber armored. Tripod mount is included, but these models are light enough to be hand held. Depth of field is 60 yards out to infinity once focused for your eyes. Less

An excellent choice for those who need extra power and brightness.
