Ready to make more putts? Scotty Cameron has you covered. The master putter designer has devised a 1 3/16th inch square piece of stainless steel that will help golfers set their balls on the right line.
The tool has a dominant center line with three smaller lines on each side of it. These lines create what Cameron calls "the railroad effect" allowing you to try to envision the way the ball is tracking toward the hole. There's a more detailed description and slide show at scottycameron.com. After watching it, you might not think spending $44 for a ball mark is such a crazy notion.
