Abstract: A putter head (1) is described wherein the putter head (1) has a putter face (4) and a linear marking (9) located on an upper surface (44) of the putter head (1). The relative angle of the putter face (4) with respect to the linear marking (9) is adjustable in order to compensate for inherent inaccuracies in a player's visual judgement when putting. In a preferred embodiment, the upper surface (44) is in the form of a rotatable disc (3) wherein the rotatable disc (3) is moveable about an axis in order to selectively adjust the relative angle between the linear marking (9) and the putter face (4).

Abstract: A putter trainer device for detecting inaccuracies in a golf puffing stroke. The puffing trainer device of the present invention is releasably (2) attached to a shaft of a golf putter and comprises two guided ramps (19A, 19B) with each ramp having an active position and a neutral position. In one embodiment, a free rolling disc magnet (20A, 20B) is located upon each guided ramp and each free rolling disc magnet is biased towards the neutral position (23A, 23B) on its respective ramp. The movement of either free rolling magnet from the neutral position to the active position is detected by magnetic reed switches (25A, 25B) located adjacent each ramp. A speaker is activated when the magnetic reed switches detect that either free rolling magnet has moved from the neutral position to the active position.

Abstract: A harness safety alarm for providing a warning in the event that a seat belt is uncoupled comprises a proximity sensor (19) connected by strap (20, 21) to a seat belt buckle (13). A detectable means (22), such as a magnet, is attached by strap (23) to the tongue (16) of the seat belt. A warning unit (30), which is mounted remotely from the proximity sensor (19), provides an audible and visual warning if the seat belt is uncoupled. In particular, if the seat belt is uncoupled, the sensing means (19) sends a radio frequency signal to the warning unit (30) to thereby activate the audible and visual warning.

Abstract: A body board (10) having a pair of side rails (13, 14), the body board (10) including a fin (20) that extends laterally from at least one side rail (14) of the body board (10).
