The Visio Aimboard compliments the Visio Laser and will give you accurate feedback on the degrees of error in your putting alignment at 3 known distances.
The triangular board has 3 sides. Each side represents a specific distance of either 5,10 or 15ft. On each side, there are markings that represent what various degrees of error would look like from that known distance.
For example, the 5ft side of the board shows marking for what 0.5, 1, 1.5 and 2 degrees of error would look like when putting from 5ft from the hole.
The board can fold up flat to allow for easy transporting and can be locked in place on the green with tee pegs through holes located either side of the board.
