The SAM Putting Backboard has been designed to be used especially with the SAM Puttlab while doing assessments and training. When a player hits putts from a distance of 10 feet with the backboard placed 18 inches behind the hole the marked lines are then relative to degrees offline the putterface is aimed at address and impact and also relates to miss directed stroke paths.
It can also be used in conjunction with the M LASER to help determine and show the alignment of a putterface at address.
