The Acer SHM-2 (the acronym is short for Simple Harmonic Motion) mallet putter was designed with counterbalancing in mind. First, the head itself is heavier than an average putter head which raises the "MOI" (or Moment of Inertia) of the head with gives added forgiveness. Secondly, the counterbalancing (we counterbalance the putter when we assemble it for you) offsets the head weight and shifts the center of gravity of the putter closer to the player’s hands. This encourages the bigger muscles in your upper body to "propel" the putter instead of using a “wristy” stroke.
Our assembled length for this putter is 37”. This is 3 inches longer than our standard length of 34 inches. We also use a longer putter grip; a premium Winn 15" (red) grip. The way to putt with this putter is by choking down to your normal length, so that the counterweighting is positioned above your hands and is effective in helping you make a good pendulum stroke. This is a great way to enjoy the benefits that a belly putter has without anchoring to your body. The SHM-2 also features a soft insert and is face balanced. This putter comes with a red Winn 15" long pistol putter grip.
