PurePuttT from GrooveFix is the first adjustable putting gate on the market. It is beautifully crafted from aircraft grade aluminum and easy to use.
Slot the two included feet on the legs of the gate, loosen the thumbscrew and slide the gate to the desired width, then tighten. PurePutt can be adjusted to any dimension between 50 mm (1.97") and 108 mm (4.25") - the size of a regulation hole) using the scale on the device.
Place the goal on your chosen line and at your chosen distance from the ball and fix it on the putting green with the tee pins supplied. The further you place the goal, the higher the degree of error.
Practice regularly with the goal to get feedback on the club face angle, the quality of the stroke at impact and putting accuracy. PurePuttT can be used in conjunction with GrooveFix's Right Angle, Doughnut and Carpet Cup training aids to gain further feedback and improve your putting statistics.
