Bushnell Universal Doubler

The Bushnell Universal Doubler multiplies magnification of the Elite binoculars, or any other binocular with 32mm or bigger objectives and modern twist-up eyecups, by 2.5x-thereby converting them effectively in to a spotting scope.  The Doubler features fully multicoated optics with a BaK-4 roof prism and rugged rubber armor.  It is friction fit, making it fairly universal.
