<p>The trolley e.g. for golf or shopping comprises a wheel-associated sensor (21, 23) to measure the distance moved by the trolley over the ground, and display means (20) adapted to give a readout in response to an input derived from the sensor (21,23). The sensor may be mechanical or electrical e.g. comprising a reed switch (21) and a magnet (23). The display (20) may be part of a self-contained detachable, programmable microprocessor-controlled apparatus which can operate in various modes to give such information as distance covered, distance remaining to a hole, best club to use, time of day, time elapsed and score. <IMAGE></p> |
