If you delay the release of the club head properly by holding the wrist angle as long as possible, the Magnetic Sliding Timing Ball will release from the grip and hit the end of the shaft at exactly the impact point in your swing. It will feel like you connected with a 300-yard drive that went right down the middle. Swing the Speed Whoosh at home, on the range, and/or prior to playing every round of golf to develop perfect timing for longer and straighter shots. Increase Your Club Head Speed with the Speed Whoosh. Set the Magnetic Timing Ball at the end of the shaft and swing the Speed Whoosh six times in a row as fast as you can. You’ll hear the sound of increasing club head speed by the “WHOOSH” it makes when you swing it. This will immediately activate the fast twitch muscle fibers used to swing your golf club. Switch to your own driver, and you’ll increase your club head speed 7 to 10 mph instantly! Repeat this action regularly to further add to your swing speed and maximize your distance off the tee.
