5. BACK TO RESULTS This plot provides you with another way to visualize a stroke The first hill represents the speed of the putter during the backstroke As the putter transitions from backstroke to follow through the velocity is instantaneously zero The second hill represents the speed of the putter during the follow through As the putter strikes the ball some of its momentum is transferred to the ball causing the putter s speed to drop momentarily Face Angle Graph Eg The Face Angle button displays a plot of the face angle throughout the entire stroke BACK TO RESULTS In this plot open face angles are given negative values and closed face angles are given positive numbers 0 degrees would be a square face angle In the example shown above the golfer begins with a face angle at address of 2 degrees open He then opens the face further during the backstroke The club face then begins to close on the follow through and crosses through square 0 degrees precisely at impact 53 V1 VISUAL PUTTING SYSTEM Face Check The Face Check function shows how well the putter face 1s aligned with the path shape After a stroke has been analyzed click this button to see the face check display gt E LF i EH L4 x i a E i E 4 1 F N Vr setae vcn V TEPETTENSZT ig a FRI UD SPEAR petrus Iur Dee Tage o D Rn e lB RETRO MODEL LIA DUET s renum If the face is square with the p

Putting System it must be calibrated Calibration Guide Track Alignment The first step of the calibration process is to determine the line along which the ball must travel to roll into the hole To begin place the black track board on the putting sutface with the track groove pointing towards the target or hole Place a golf ball in the track groove near the middle of the board and putt it down the track towards the hole Depending on the final resting place of the ball rotate or adjust the track board and repeat this process to find a track board position that guides the ball consistently into the target hole Accuracy is important during this step because the guide track defines the ideal ball trajectory to the hole The V1 Visual Putting System will automatically detect if a left handed player is putting the ball If you have a target hole placed for left handed students tap a few balls down the alignment track in the opposite direction to ensure the lefty target hole is in the correct position Without disturbing the position of the alignment track carefully place the calibration target on top of the track board so that the markings on each end of the calibration target line up with the groove on the track board as shown in the image at the top of the next page 21 V1 VISUAL PUTTING SYSTEM The target pattern is now aligned with the ideal path to the hole as determined by using the alignment track board Calibration Process
25. The calibration process uses the included target which consists of a field of dots spaced one inch apart to teach the system how to measure distances as seen by the camera Also calibrating the system to the target pattern eliminates camcorder lens distortion and other factors that can reduce measurement accuracy To calibrate the system to the target pattern first make sure V1 Putt is in RECORD mode with AUTO OFF so that movement does not trigger the system The buttons to the right of the video window should appear as shown RECORD should be green and AUTO OFF should be yellow While looking at the video window in V1 Putt adjust the position and zoom of the camcorder until the complete target dot pattern is visible aligned and centered on the computer screen The outermost dots on the right and left edges of the pattern must be just inside the edge of the video window as shown in the image below 22 V1 VISUAL PUTTING SYSTEM When the calibration target is aligned as shown above click SETTINGS and then click the CALIBRATE button to begin analyzing the dot pattern image If the system is able to calibrate properly the message Calibration successful will be displayed in small text above the video window If the calibration process fails for any reason an error message will be displayed Typically a failure results if V1 Putt cannot locate all of the dots in the pattern This can occut if either the outermost d
26. The following section desctibes several typical stroke problems that you will encounter when analyzing a putting motion Address Alignment There are several things you should look for at the address position Of course the putter head should be square and aligned to the center of the face You can visually see how well your student does this by looking at the live video before the putt If the student is not positioning the putter correctly Le setting up on the toe or misreading the putt ask them to glance at the monitor so you can point this out before they make a sttoke If a student consistently aligns the ball towards the toe or heel it may indicate that the shape or design of the putter head isn t the best for the student If the student is not comfortable looking ovet the putter with the sweet spot aligned to the center of the ball then experiment with another type of puttet With a camera facing the student in live video mode you can show your student how their stance and position compares to the ideal form The putter head should be exactly between their feet Their arms should hang naturally and not be excessively bent at the elbow Their feet should be spaced just about shoulder width A line drawn between the two shoulders should be level With a ground level zoomed in view you can measure the lie angle at address Knowing the lie angle and eye alignment you can quickly determine it the putter shaft length is correc
