I usually demonstrate it by simply twanging a blank shaft using a bench vise, V block clamp and tip weight. I use a shaft I've pulled out of a Callaway that I have premarked with the spine and FLO. I start by twanging it with the logo up and show how much bob and weave we get. I let the shaft oscilate until it's almost dead because it shows how the shaft will seek the plane of least resistance. I then rotate to FLO and repeat. They are always amazed and it's simple and effective. Using a quality OEM shaft also achieves another goal and that is that it shatters the mythe that OEM shafts are automatically going to be a quality product.

There is no such thing as Spines


I suggest this simple test for doubters and customers alike. Take a steel shaft and a graphite shaft. Place in your spine detector and mark the spine. Now take the marked shaft and put it on your deflection board with the mark facing you. Place the weight one inch from the tip and allow shaft to bend. Mark on deflection chart where the center of the tip comes to rest. Rotate the shaft to have the mark up or down and repeat the deflection measurement. Mark where the center of the shaft tip comes to rest. Most often you will find the two deflection marks about one half a flex apart. HOW CAN THE SAME SHAFT HAVE TWO DIFFERENT FLEXES?  The weaker the "spine" the less flex difference you will see!.
This is a great sales tool to use on your customers! Show the value of your services.
Try it!
