The length of the rod is adjustable and defines the radius of the arc of motion of the club relative to the golfer, whereby a putter is constrained by the device to swing in a precisely defined path to teach the golfer a repetitive stroke. An indicator loop attached to the rod enables the golfer to monitor the position of the putter shaft within the loop as a putting stroke is made. ## Claims ### Claim 1 A device for use with a golf putter having a putter head and a shaft; said device for determining the position of a golfer's hands during the execution of a putting stroke along a preselected path and for maintaining the putter head in a precise relationship on that path with respect to the golfer to develop a repetitive stroke comprising: a neck engaging member; an elongated rod having first and second ends, said first end connected to the neck engaging member; the length of the elongated rod defining the radius of the arc of motion of the putter relative to the golfer; a quick release connector for releasably connecting the second end of the rod to the putter head; and, an indicator attachable to the elongated rod for determining the position of the golf putter shaft relative to the central pivot point defining the radius of arc of motion of the putter, said indicator being an elongated loop having elongated sides; a fixed end of said loop attached to said rod and a free end of said loop forming an opening with respect to the fixed end whereby the opening is structured to receive the putter head shaft when the device is used, said putter shaft being centrally positioned relative to the elongated sides of the indicator loop and whereby said putter shaft maintains its position relative to the indicator loop during the execution of a proper golf putting stroke and whereby the shaft moves to either one of said elongated sides of said indicator loop when an improper putting stroke is made. ### Claim 2 (depends on 1) The device of claim 1 wherein the elongated rod is formed of two telescoping members frictionally connected to each other by a friction joint. ### Claim 3 (depends on 1) The device of claim 1 wherein the quick release connector is a separable fastener. ### Claim 4 (depends on 3) The device of claim 3 wherein the separable fastener includes a complimentary separable fastener section connected to the end of the elongated rod and a second complimentary separable fastener section adopted to be connected to the putter head. ### Claim 5 (depends on 1) The device of claim 1 wherein the neck engaging member is a loop having an opening sized to permit the loop to the placed around the neck of the golfer. ### Claim 6 (depends on 8) The device of claim 8 wherein the quick release connector is attachable to the end of the elongated rod opposite the loop. ### Claim 7 (depends on 1) The device of claim 1 wherein the indicator loop includes a means for rotatably positioning the loop on the rod. ### Claim 8 (depends on 1) The device of claim 1 further including a flexible coupling adapted to be located between said elongated rod and the putter head. ### Claim 9 (depends on 1) The device of claim 1 wherein the quick release connector is a threaded coupling. ### Claim 10 A device for practicing a golf putting stroke with a golf putter having a putter head and a shaft and for determining the position of a golfer's hands during the execution of a putting stroke along a preselected path while maintaining the putter head in a precise relationship on that path with respect to the golfer to develop a repetitive stroke comprising: a neck engaging member; an elongated rod having one end connected with said neck engaging member. a quick release connector for releasably connecting an opposite end of the rod to the putter head; and, an indicator affixed to said elongated rod and having spaced members; an opening between said spaced members to receive the shaft of the putter therebetween at a predetermined distance between said spaced members prior to the execution of the putting stroke; variations in the distance of the shaft between said spaced members providing an indication of the movement of the position of the golfer's hands during the execution of the stroke. ### Claim 11 (depends on 10) The device of claim 10 wherein said indicator is an elongated rigid loop having spaced legs forming said spaced members.
