Abstract: The invention provides a novel combination tool for the repair of ball marks on a golf green and for assisting a golfer in determining the slope of a golf green. The device is compact and easily capable of being carried in a golfer's pocket. The device comprises an elongated, thin body with opposite ends and a substantially planar bottom surface. Each of the opposite ends is equipped with two spade-like prongs, which are well-adapted for the repair of ball marks on a golf green. The device further comprises a frame for housing a bubble-type level, which is attached to the top surface of the device, and is capable of assisting a golfer in making a quick and accurate determination of the slope of a golf green.
