The Visio colour coded gates come in a pack of 3 sizes (RED 60mm, SILVER 55mm and BLACK 50mm) which when placed at specific distances from the ball, on your chosen target line, will create a specific angle of error that you will need to achieve in order to successfully putt the ball through the gate.
50mm @ 17 inches requires less than 0.5 degree of error
50mm @ 11 inches requires less than 0.75 degree of error
55mm @ 14 inches requires less than 1 degree of error
55mm @ 19 inches requires less than 0.75 degree of error
60mm @ 40 inches requires less than 0.5 degrees of error
60mm @ 20 inches requires less than 1 degree of error
The putting gates also come with an indoor holder so you can use the gates for your indoor putting practice.
