The key to great putting is practise. The PUTTOUT PREMIUM PRESSURE PUTT TRAINER can be taken anywhere. With its patented parabolic shaped hole, every good putt is returned to the player the same distance it would have travelled beyond the hole if they had missed it. Only absolutely perfect putts are kept in the hole, so practise can begin! To make a good putt, you must pass the break point and the ball must get over the base of the ramp that represents the size of the hole. If you can’t overcome this, the ball has no chance to fall into the hole on a real golf course.
