Impact Ball Liner
you place the face of the putter squarely on the ball?
Imagine the back of the ball was flat and perfectly aligned to the
cup. Could you place the face of the putter squarely on the ball?
Yes! The Ball Liner is a stencil that puts a line on the back of the
ball to give you a flat target for your putter face. Short putts
just got a lot easier.
Line up your ball to the target. Focus your attention on the black
line, and put your putter on this "flat" surface. Make a confident
stroke delivering the putter face squarely to the back line... and
listen for the ball to drop.
