The invention relates to an arrangement (1) for use in conjunction with playing golf to enable a golfer (2) to find the ball (3) easily in the terrain (4) on the golf course. The arrangement (1) comprises on the one hand the golf ball (3) provided with an electrically conducting pattern (7) which is resonant at microwave frequencies. The arrangement (1) also comprises hand-held equipment comprising a transmitter which generates output effect at a microwave frequency tuned for an applied golf ball pattern (7) and a receiver tuned to the narrow-band output frequency of the transmitter, so that the marked golf ball (3) in question can now be readily identified directionally from non-metallic surroundings. Different polarization is used in conjunction with this for transmission and reception. |
