Line up better using Scotty's precision milled stainless steel ball alignment tool. The concept is simple. Mark your putt with the tool, setting it behind the ball while using a marking on your golf ball to line up the putt. Leave the ball and tool on the green. Then, step back and envision a "track" toward the cup using the tool's three black sight lines in conjunction with the line on your ball. Dial in your aim using the smaller gold "tick" marks on the tool. Pocket the marker and hit your putt.
