The Black Mamba putter is designed to address the number one reason for missed putts�poor alignment. The Black Mamba features four alignment aids that will help you make more putts � The patented Total Eclipse Alignment Circle, the patented Dyna-Groove, the long white center line and the extended mallet shape. The Total Eclipse Circle will make sure your eyes are over the ball, the Dyna-Groove will make sure your putter face is square to the target and the white center line along with the extended mallet shape will make sure you are in line with the hole.
