Momentus Men's Speed Whoosh Golf Swing Trainer with Training Grip
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.
