John B. Hoeflich, COO: "Many alignment putters can look square in the address position but they really aren't lined up to the hole. The PIPE has '3-dimensional alignment' to solve that problem. Don't believe it? Ask somebody who has one and is making more putts than his buddies."

How it works: The white cylinder, or pipe, provides a strong visual display of where the putter is aimed. (The pipe is 1.68 inches, which is the same diameter as a golf ball.) A heavy tungsten rear plug (15-percent of the putter weight) contributes to its high MOI and low center of gravity so putts skid less and start rolling sooner.
