A putter trainer device for detecting inaccuracies in a golf putting stroke. The putting trainer device of the present invention is releasably ( 2 ) attached to a shaft of a golf putter and comprises two guided ramps ( 19 A, 19 B) with each ramp having an active position and a neutral position. In one embodiment, a free rolling disc magnet ( 20 A, 20 B) is located upon each guided ramp and each free rolling disc magnet is biased towards the neutral position ( 23 A, 23 B) 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 ( 25 A, 25 B) 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.
