The Bushnell 7x50 Permafocus Binocular is a full sized 7x 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 7x50 model is well-suited to stadium sports where you are more distant from the field, and with its 50mm objective lenses it provides a very bright view.
