Golf putter head with a visual alignment aid and an increased moment of inertia

A golf putter head comprising:

• a face member having a heel end, a toe end, a top rail extending between the heel and toe ends, a front surface arranged for impacting a golf ball, and a back surface;
• a first arm extending substantially rearwardly from the back surface of said face member at the heel end thereof;
• a second arm extending substantially rearwardly from the back surface of said face member at the toe end thereof;
• a central member having an inner end connected to the back surface of said face member intermediate the heel and toe ends thereof, said central member extending rearwardly from said face member and including a pair of opposed side walls at said inner end, said central member also including a pair of wing portions connecting said central member to said first and second arms rearwardly of said face member;
• said central member and said first arm defining a first opening therebetween adjacent the heel end of said face member;
• said central member and said second arm defining a second opening therebetween adjacent the toe end of said face member;
• said central member having an outer end thereof extending rearwardly of said wing portions;
• and
• said first and second arms having top surfaces that slope downwardly as said first and second arms extend away from said face member.
