I think this is the best ball marker there is. It has several different options for drawing lines. It also clips onto the ball very securely so you can easily draw the lines without having to worry about it slipping and causing you to draw uneven lines. The line in the middle is fat enough to fit a thick tipped sharpie in which other markers only have thin lines that force you to use a thinner tipped sharpie.Get more detail about Callaway Line-M-UP Pro Ball Marker.
