A device for improving a golf stance and swing has a clip, an arm, a mount, and an indicator block. The clip allows the device to be secured to a golf club, while the arm allows the mount and connected indicator block to be centered with respect to the golf club. The mount has a carriage which slides along a corresponding track on the arm, and a perpendicular rod about which the indicator block can rotate. The indicator block has three faces, two lateral faces and a top face. When the indicator block is centered on a head of a golf club, it can be used to gauge the correct distance from the ball a golfer should stand. Only the top face of the indicator block will be visible when standing the correct distance from the ball. The faces of the indicator block are color coded to increase usability.
