Trident Align is the world's first fully adjustable ball marker and has been deemed legal for tournament play by USGA and R&A. Why would you need to adjust the line on your ball marker, I hear you ask?
Well firstly, it allows the golfer to begin fine-tuning the aim of their putt even when the ball is not in place on the ground. The Trident Align has a fairly weighty black base and sitting on top is the adjustable white section, which can slide round to the left or right.
