<p>A device for practising golf putting comprises a base or mat (10) having at least one row of electromagnetic sensors (14, 15, 20, 21) which may be capacitively operated switches or magnetically activated reed relays responsive to the proximity of a magnet (19) placed on the sole of a golf putter head (23). The electromagnetic sensors (14, 15, 20, 21) are arranged on the base or mat (10) parallel to a straight path of travel (16) defined thereon. Audio generators are connected to the output of the electromagnetic sensors (14, 15, 20, 21). If the putter head (23) deviates from the straight path of travel (16) during a putting stroke, the audio signal generators will emit an audible signal indicative of such deviation.</p> |
