Since golf started players have been in search of the perfect putting stroke. They are constantly looking for new and advanced technology and more effective methods to improve their putting. There are many factors that have to come together to hit a perfect putt, but all are irrelevant if one is aiming incorrectly. It is thought that over 80% of putting errors are due to aiming the putterface poorly. With other sports where accurate aiming is important (shooting a gun, playing snooker, throwing a dart) one puts their eyes on the target line behind the projectile. This is the best way to accurately gauge where the target is. Aiming a putter to the target is like shooting a gun while looking at the barrel from the side and is therefore extremely difficult to get right. How can we solve this problem??
