Abstract

A putter has a chamber extending lengthwise of its head in which there is a battery powered motor driving a fly wheel at the outer end of the head at a rate such that a gyroscopic force is provided adequate to stabilize the head against being turned by the golfer as a putt is made. The head is shown as symmetrical so that a putter may be used by either a left-handed or a right-handed golfer and the head may be weighted as desired by placing one or more weights within the chamber. The switch control of the circuit may be manually operated or of the mercury type.
