The present invention extends to a digital compass ball marker that can be used to provide timely information to assist the golfer in determining a direction and force for a golf shot on a green. The digital compass ball marker can output this information using minimal information input by the golfer so that the use of the ball marker does not slow play, and in many cases, can speed play. The information provided by the ball marker can include a force with which to hit the shot and a direction to aim.
