Momentus Men's Speed Whoosh Golf Swing Trainer with training grip.
Correct your swing habits that you've developed through self-teaching with the timing ball training. The Speed Whoosh's most distinctive feature is its movable timing ball, which you set towards the grip and swing. When you swing, the ball slides, and you can check if you're swinging correctly by the ball's movement and sound! With repeated swings, you can train your body to remember the correct impact timing. Just 6 swings are enough?!
The Speed Whoosh works in two ways:
1) Increases club head speed and extends distance.
2) Improves timing with its unique magnetic timing ball.
The Speed Whoosh is a revolutionary club head speed accelerator that activates fast-twitch muscle fibers, allowing you to swing the club 7-10 mph faster after just 6 swings! This translates to a 21-30 yard increase in distance! The magnetic timing ball slides down the shaft, perfecting your timing and eliminating the tendency for golfers to cast the club from the top. The Speed Whoosh instantly increases your club head speed and gives you a perfect release feel every time.
