  • Combination golf ball retriever and trap rake
    Patent number: 5311733
    Abstract: A golf ball retriever which can also be used as a trap rake. A head mounted upon an extendible handle includes a plurality of elongated spaced tines extending from pivoted arms. The arms are pivotal between a folded storage position and an extended open operative position and the tines are separated by a distance slightly less than the diameter of a golf ball whereby the retriever head may be "raked" through a water hazard to retrieve the balls. The rake-like orientation of the tines also permits the head to smooth sand traps.
