Inside Approach Swingyde
I saw a guy at the PGA Superstore in Chandler, AZ using one of these in the hitting bay and he had a really nice swing. I asked him how he liked it and he said he was just trying it out but that when using it, he hit the ball 10 yds further in the simulator.
I decided to try it on the simulator and I found that this little gadget helped me get into a better position on the back swing, making sure I had enough wrist cock (I tend to not have enough), but what was even better for me was to try to maintain the hinge in my wrist on the way down and then follow through in my release.
The very next round I played at Whirlwind Devil's Claw in Chandler, Arizona and I shot my best score of a 77. I don't know if it was coincidence or the Swingyde but I ordered one right away and I love it! You see, if you are using the Swingyde and you don't follow through properly, the guide will let you know that. It's feedback that you can feel and see and use on the driving range.
