GSA PRO is the application available on the market that enables golfers to instantly learn about their golf swings with ease. It records your swing motion and sends the information straight to your smart phone by using this GSA PRO app. Amongst the many features like calculating your tempo, Face Angle, Club Head Speed and Attainable Ball Distance, it can actually record your swing locus and compare that to your previous best, or your coach's swing locus, a graphical feedback that can improve your understanding of your swing. You will need a 3BaysGSA PRO device to connect with GSA PRO if you want to capture your swing motion analysis.

Golfers can instantly see on the GSA PRO app -
1. 3D animations compiled from the 10,000 data points captured per swing
2. The following 10 parameters

Back Swing Time
Down Swing Time
Face Angle
Club Head Speed
Impact Force
Attainable Ball Speed (ABS)
Attainable Shot Distance (ASD)
Swing Path

3. Comparisons of your current swings with your best swings.
4. Your historical swing performance

The patented 3BaysGSA PRO is the world's lightest Golf Swing Analyzer using advanced sensor technology to capture your swing data. It provides the fastest feedback on your iOS devices (iPhone 3GS, 4G, 4GS, iPad 1, iPad 2, New iPad). Its plug and play technology makes the 3BaysGSA PRO completely unobtrusive and free from obstruction to your set up or swing, and it does not affect the weight distribution of your golf club.

"Now with the 3BaysGSA we have entered the next generation of learning, which will enable faster improvements than ever before. I really do believe this product can and will help every golfer improve their golf whatever your level." - Robert Eastwood, British PGA Member Class AA

"This is easy to use. Place the analyzer into the end of the grip; hit the ball and your student instantly sees on their phone - club head speed, tempo, impact force, etc. 10,000 data points instantly, it is just amazing and fun. It's simple. It's easy. I just think it's simply the best." - Penny Pulz, 2 time LPGA champion, Top 50 Golf Teacher

Ratings and Reviews

Great device......but,

desk pilot

Small and very easy to use. App is great on the iPad and Bluetooth transmission is very quick. Had an initial problem with some of the readings not working, but the recent update sorted that. I do think that you need to work out if the distance readings are accurate for you. Mine seem to be about 10% higher than I know my distances to be.(7 iron shows 170 yards when I know that it is 155 in reality).
However.....I contacted 3Bays over two weeks ago with some questions regarding the readings and I have heard nothing. Not great customer service for something that costs £200.
Having said that, great device and a lot less expensive than some others on the market.

Great for swing analysis


This does work! The Bluetooth gizmo is tiny but worked first time very well. Gave me info on speed, and power and swing plane variations.

It is fun but used wisely over a while will chart swing improvements. At least you can discuss results with your PGA teacher with some accurate data.

Putt is the other app but can't seem to discover whether another pricey gizmo is needed?! But then there are other apps for this as there are gsas.

Great price of kit


Use this all the time down the range lots of useful information. Would like to see a competition mode. Like the sc100. Where it challenges you to hit certain distances. To keep you focused. But no the less this is great addition to your bag
