A putting practice aid (10) with a frame (16) which mounts a light unit (18) to shine the image of a golf hole on the ground. The frame (16) is mounted on two feet (14) one of which contains beam transmitters (30) producing infra red beams (34) which will be crossed by a golf ball aimed at the illumination of the hole, and the other contains respective corresponding beam receivers (32). The timing and duration of the break caused by a golf ball of the respective beams (34) produced by the transmitters (30) is used to determine the outcome of a shot aimed at the illuminated circle (28) to indicate whether the ball would have entered a real golf hole at this point, and this is communicated by an audible message.
