<p>A device for determining a golf play parameter comprising means (7) for measuring distance to an object. These measuring means transmit electromagnetic radiation to the object, receive the electromagnetic radiation reflected back by said object and determine the distance to the object by reference to the radiation transmitted and the reflected radiation received. The device also comprises memory means (5, 6) containing data regarding at least one golf play parameter determined by distance to the object, processing means (1) for interrogating the memory means to provide a play parameter dictated by the distance determined, and interface means (2) for indicating the play parameter obtained. In a preferred embodiment, the distance to the object is determined by measuring the elapse of time between transmission of the electromagnetic radiation and reception of the reflected radiation. Preferably, the electromagnetic radiation is in the infrared waveband.</p> |
