RFQ Details

Setup the putter laser:
1. Open the battery cover, then put a battery into the box of putter laser. Notice the polarity of battery.
2. Unscrew the putter laser and adjust the lasing direction to the putting line. Clamp the putter laser on the shaft.
3. Adjust the laser to align the lasing direction that perpendicular to the central line on head of shaft (put the shaft on table and alignment with a rule). Adjust the laser parallel with head of shaft (alignment it after put the shaft on table).
4. Mark a straight line on ground. Then align the central line of head to the straight line and observe if the laser on the straight line.
How to use the putter laser:
Putt on green:
Press the button to turn on laser. According to the slope of green to target the line, and align the laser line to target. The head of shaft is perpendicular to golf ball. Now we can image that a putting line between the ball and the red point. Adjust the feet to parallel with the putting line to putt the ball. The practice will help you to hole out successfully. If the green is flat, you can align the laser line to hole directly. (Please use the cant of shaft to help the adjustment of distance between laser pointer and target.)
Putting practice:
Stand by a wall at a distance to putt. Pose your shoulder perpendicular to the wall. Turn on the laser and putt. You can observe a trajectory of laser line when you putt. The trajectory should be parallel with your shoulder and perpendicular to the wall. If the trajectory bevels your shoulder, that indicates the putt is awry. The training can help the putter adjusting the pose and correcting putt with repeat practices.
