You can’t expect to get better at golfing if you don’t practice often and work hard to improve your technique. The OnsongSwing LED Golf Swing Aid can help. It provides you real-time feedback to help you focus on accelerating the club head through the ball. The display shows club head acceleration, swing speed, and ball impact.
The device weighs only 44 grams, so it doesn’t get in your way. It can monitor your swing speed at a rate of 1000 times per second.
