What is Shaft Truing?
The fact is, no shaft is perfectly round, straight or stiff throughout it's length. Despite modern manufacturing techniques every golf shaft, whether steel or composite, remains as unique as a fingerprint and cannot be fully analyzed until after the shaft has been manufactured.
The PPOP, or Principal Planar Oscillation Plane, is the plane of assembly in which the shaft is most stable when striking a ball.
The Shaft PUREing process involves identifying asymetries within each shaft, using patent-pending state-of-the-art computerized locating equipment to pinpoint and correctly align the PPOP into the clubhead to optimize shaft stability and performance — ensuring the uniform matching of clubs within a set and allowing each club to perform the best of it's manufactured capability.
The Shaft PUREing printout provides visible proof that your shaft(s) has been "PURED" by seahorse golf technicians. The printout data that accompanies every shaft indicates its performance characteristics both prior to and following the Shaft PUREing process.
The red graph to the right shows how erratically a
typical shaft can bend when not properly positioned in the clubhead.
The green graph to the right shows how consistently the same shaft bends in a pure consistent back and forth motion after proper alignment in the same clubhead.
A Shaft Analysis Sheet (left) is produced for each shaft or club submitted for Shaft PUREing showing the shaft's oscillation both before and after spine detection. Included with each shaft, these sheets provide visual confirmation of the shaft's improved symmetry with the spine positioned neutral to the target.
