GSA Pro - Golf Swing Analyzer by 3Bays


The new GSA Pro Golf Swing Analyzer for Apple iPhone is like a reduced Trackman to record the swing motion and sends about 10'000 measured data points streight to the iPhone APP to analyze and visualize the swing.


The device needs to be plugged at the end of the club, where the hole is from the grip. Then it has to be alligned with the mark on the grip for the correct position.

After this, the device is ready and the iPhone APP has to be started and the club has to be selected to use. After this, the device will record every swing and transmit the data after the swing directly to the APP. Befor the swing, you have to make sure, the blue light from the device is continiously on, then the device is ready. Sometimes the club has to be positioned in the pre shot position for 2 seconds, that the device recognizes that the player is ready to swing.

There is not intervention needed from the user after the swing, so it's possible to hit a lot of balls with the same club without watching to the iPhone.

After this, the swings can be reviewed. 

The swing can be reviewed from the front or from the side. The swing can be reviewed in realtime or in 1/4 or 1/8 slow-motion.

The body showed is static and has always the same moves. The relevant point is the end of the orange line which represents the current swing. The green line ist the best swing selected from the past.

To switch beween the recorded swings, just swipe with the finger to the right or left.

The following data will be analyzed:


Club Head Speed and ASD (Attainable Shot Distance) are very important for each golfer. As the device is not able to recognize if the golf ball was hitted correctly, this is only a theoretical value. If you hit the ball perfectly, then it would fly that much long.

We did several tests and the ASD looks very accurate. 

By tab into the boxes of the values, the history graph of the data will be showed for the selected club:

The APP is done very well and it works very stable and fast on an iPhone 4s. The transmition of the data is stable as well if the distance to the device is not to far away. Best is to place the iPhone into the ballbox in front of you where you practice your swings.

Pairing the device the first time is very sinple and guided by a wizard. After this, there is a function to verify the connection  before practice:


Conclusion

The device works very well and can help you the make your swings more stable and consistent. It will not help you to hit the ball correctly, but with a perfect swing, it's easier to hit the ball.

It will save you the money for the Trackman sessions and waittime to use the Trackman infrastructure.

I can recommend this utility for beginners and high handicaper's like me. The device shows exaclty what my Golf Pro is always telling to me. But to be honest, it will not replace the regular Pro sessions you need to go forward and lower your handicap.

In Switzerland the device is available here: XLGolf.ch for CHF 259.-
