It has been designed to help provide both players and coaches with accurate feedback on the players perception relative to the target at set-up, as well as feedback on the starting direction of the ball.
The device when set up creates a linear reference along the target line to help players appreciate if the “straight line looks straight”. The device also creates a perpendicular reference to the target line so players can appreciate if “square looks square”. The player or coach can then adjust the players set up or head position so that they can gain a better perception of straight/square which as a consequence can help a players putter aim/targeting on the golf course.
The T-LINE can also be used to measure the accuracy of the ball start line, as the 19.75-inch Linear target line has been designed and made wide enough to roll putts along and give the most accurate feedback on face angle at impact together with face strike location.
