ABSTRACT:
Method and apparatus for measuring the green-speed of a putting green including a golf ball rolling ramp. The ramp is supported by adjustable length legs above a green surface at a selected angle. A level vial attached to the apparatus is used to determine when the ramp is at the selected angle. A plurality of parallel grooves extend the entire length of the rolling ramp and allow for sequentially rolling a plurality of golf balls onto a putting green surface. Located at the upper end of each groove is a trigger mechanism for each of said grooves, including a trigger support block and a trigger arm pivotally movable thereon for releasing the golf balls into the grooves and down the ramp. The forward or release end of the ramp is curved for releasing the balls parallel to the local horizontal relative to the putting green surface.
