Basically each club has a moment of inertia (MOI) that may or may not be suited to your swing. By adding an adjustable weight in the butt end of the grip of your driver, you are able to change the MOI of your driver.
Optimizing the MOI stabilises the golf driver at impact and results in you hitting the ball out of the middle of the club more consistently with greater ball speed. This in turns means that your shots travel further and straighter.
To find my optimum MOI we first added a face sticker to measure the impact position of the ball on the face of my driver . The results weren’t bad, but they were about to get better. Ed then added the Balance Certifed Shaft Stabliser to the butt of the club.
On the stabiliser are 2 moveable weights that can be moved to either end of the club or split top and bottom or any point in between.
Testing with the various weights showed that when I had both the weights in the bottom position I not only had more centre strikes, but using Trackman I also had a tighter dispersion and more distance.

Grey: No weights
Yellow: Weights Apart
Pink: Weights Bottom
Red: Weights Top
The Shaft Stabliser is easy to adjust and fit if you want to play around with it and the results are certainly impressive.
So the next time someone says they can't hit a driver, give them some sympathy as they may have a point!
