Brand new and high quality Learn to stop your hands from "flipping" during your swing and develop a repeatable, ball-first, solid swing that will improve your consistency, increase power and distance. Get instant feedback as you practice your golf swing. If it hits your side before hitting the ball, it means your wrist flips and your body stops spinning during the golf swing. Work on every aspect of your golf swing with this golf training aid - correct strap, wrist hinge, correct swing plane, firm impact, correct setup and correct body rotation. Will help you train your hand to hit the ball and square the club face for a more powerful hitting position. By improving your muscle memory, you'll gain power, distance and more control over your golf ball. Just 10 minutes a day can make a huge difference to your golf game. Learn the correct swing plane to get rid of "over-the-top swings" that produce high slices or "hooks." notes: Due to manual measurement, please allow 1-2 cm error.
