发明名称 Golfer's combined divot repair and distance measuring device
摘要 A pocket-sized divot repair tool which has two strong, thin metal prongs rigidly attached to a disc-shaped handle which contains a spool of very fine, high-strength, man-made line of substantial length fastened to a hookclamp which may be unsnapped from the handle, hooked around a golf flagstick and played out in order to measure relative distance to competing golf balls. The line is retrieved by opening a crank hinged to the spool, after which the crank is closed and the hook/clamp snapped back onto the handle locking itself and the spool firmly into place.
