A drag member having a flexible, self-sustaining form is centrally attached to a golf ball by a flexible elongated member. The drag member comprises a substantially planar central portion and radial segments extending outwardly from the central portion. When the golf ball is driven through the air, the drag member is pulled behind the ball transverse to the trajectory of the ball. The drag member defines an aerodynamically designed drag surface area of initially fixed dimensions which vary inversely with the flight speed of the device. The drag member acts to shorten the flight of the golf ball and to provide a flight trajectory for the attached golf ball similar to that of a conventional golf ball.
