The Bushnell 12x50 Permafocus Binocular is a full sized 12x unit with a focus-free design, so that you'll never miss the action while fumbling to focus.  It is designed only for use with distant subjects.  Just aim and your subject comes into clear view.  This 12x50 model is well-suited to sports where you are quite distant from the action, such as a boat race or an extreme skiing competition, and with its 50mm objective lenses it provides a very bright view.
