Golf practice made easy. The perfect accessory to your set of golf clubs. The Momentus Golf Speed Whoosh has a Magnetic Sliding Timing Ball at the grip end of the shaft to develop the proper timing and release during the swing. As you make practice swings with the Speed Whoosh, the magnetic timing ball will give you immediate feedback as to whether you’re casting the club, (releasing the club head too early), or releasing the club head at the ideal time. If you cast the club, the Magnetic Sliding Timing Ball will release from the grip too early and hit at the end of the shaft before impact. The Speed Whoosh works 2 ways: 1) It increases club head speed, resulting in more distance & 2) The proprietary Magnetic Timing Ball improves timing. The Speed Whoosh is a revolutionary club head speed accelerator that activates the fast twitch muscle fibers to swing the club 7-10 mph faster after only 6 swings! This is an increase of 21-30 yards in carry distance! The Magnetic Timing Ball slides down the shaft to perfect your timing and eliminates the tendency most golfers have to cast the club from the top. The Speed Whoosh will increase your club head speed instantly and give you the sense of the perfect release every time. Instructions: After warming up, swing 10 to 15 times with the ball at the end of the club as fast as you can to activate the fast twitch muscle fibers for a dramatic boost in club head speed with your own driver. With the ball magnetically stuck to the grip, make 10 to 15 swings in a row to fine tune your release making sure the ball impacts the tip of the club directly out in front of the impact zone.
