Improve your putting accuracy by lining up better using Scotty's precision milled stainless steel ball alignment tool. The concept is simple. Using a line on your Titleist golf ball, mark your putt and leave the tool behind the ball. Then, step back and envision a "track" toward the cup using the tool's three dark gray sight lines in conjunction with the line on your ball. Dial in your aim using the smaller royal blue "tick" marks on the tool. Pocket the marker and make your putt.
