A device that attaches to the golf club usually the putter that determines the direction the golf ball must be stroked to compensate for the slope of the green. The device is detachably fastened to the golf club by an attachment lock or a strap for easy removal. The putting direction is determined by the golfer by standing away from the golf ball and viewing the golf ball and the golf hole or pin. Holding the golf club with one hand on the top of the golf club and the other hand at the bottom of the golf club aligns the shaft of the golf club so that the club shaft runs thru the golf ball on the bottom and the golf hole or pin on the top of the club shaft. The golfer than consults at the PUTTER SCOPE that is attached to the golf club in a location that does not interfere with the view of the golf ball or the golf hole. Holding the golf club firmly with the lower hand the golfer than moves the upper hand either to the left or right until the indicator needle of the PUTTER SCOPE is pointing straight down. The shaft of the golf club is now aligned with the direction the golf ball must be aimed to compensate for the slope of the green.
1. A device to be attached to a golf club usually a putter to determine the direction a golf ball must be stroked to compensate for the slope of the putting green. Said aiming device comprising:
(a) A device composed of a needle or indicator which is attached near the top of the device and extends almost to the bottom of the device in a manner that allows the needle or indicator to move freely from the left side to the right side of the device. Said device is enclosed with an attachment lock or strap for easy removal or attachment to the golf club shaft.
 The objective of the game of golf is to complete each golf hole in as few strokes as possible. Once the golfer has hit the golf ball on the green golfer tries to hit the ball into the golf hole with as few strokes as possible. To make this more challenging the golf green is usually built with a sloping surface to make the golfer compensate for this slope by aiming in a direction which is not directly at the hole or pin. Selecting the correct direction is often very difficult and represents one of the most frustrating aspects of golf. Although some existing devices can measure the slope of the green this device provides an explicit direction for the golfer to aim and is easy to understand and master.
 The primary objective of the invention is to assist golfers in determining the direction of a putting stroke to correct for the slope of a green. The invention is small in size and can be easily attached to the shaft of a golf putter. The operation of the invention is straight forward and easy to master. Golfers can leave the invention attached while playing or can detach the invention and only attach the invention when a difficult putt with considerable slope is evident.
 As shown in FIGS. 1-5, an aiming device intended to assist golfers in developing a direction for putting that will correct for the sloping surface of the golf green and is composed of the unit itself a freely swinging needle or indicator and an attachment lock or strap for attaching to the putter shaft. As shown in FIGS. 4 & 5 the golfer stands a short distance away from the golf ball facing the golf hole or pin. Holding the putter with this invention attached with one hand on the top of the club shaft and the other hand on the lower shaft the putter is rotated until the golf club shaft is lined up with a line of site running over the golf ball and directly to the golf hole or pin. This invention will indicate if there is slop to the green on this line of site by pointing either to the left or right of the straight down position. The lower hand is held firmly so that the line of site still passes over the golf ball and the upper hand is moved either to the left or right until the indicator needle is pointing straight down. The putter shaft is now lined up with a direction that compensates for the slope of the green. Once the golfer sees the direction where the golf ball must be aimed a normal putting position is assumed and the golf ball stroked. If when lining up the put as in FIG. 4 the needle indicator points straight down and is not off center the golfer knows there is no slope in the green from this position.
FIG. 1 shows the front view of the invention by itself and a side view. In both views the needle indicator is pointing straight down.
FIG. 2 shows a side view of the invention attached to the shaft of the golf club using the attachment lock. The invention can also be attached to the shaft of the golf club with a strap (not shown).
FIG. 3 shows the Putter attachment lock.
FIG. 4 shows the golfer standing on the green away from the golf ball facing the hole or pin. The golfer is holding the golf club shaft with one hand on the top of the golf shaft and the other hand on the bottom of the golf shaft. By keeping the bottom hand firmly sited over the golf ball the upper hand is moved either to the right or left until the top of the shaft is lined up with the golf hole or pin. The needle indicator is pointing away from straight down indication there is a slope to the green.
FIG. 5 keeping the bottom hand firm the golfer moves the top hand either to the left or right until the needle indicator is pointing straight down. The shaft of the golf is now pointing towards the direction where the putt must be aimed to correct for the slope of the green.
