When most amateurs practice golf, they go straight to the driving range and hit driver after driver. On a typical course one hits driver 14 times but could hit a putter 36 or more times. The quickest way to shave strokes off of one’s scores and lower the handicap is to improve putting.

In the day of apps and mobile technology there are some very cool systems on the market which can analyze golf swings and putting strokes, giving the user a wealth of very valuable information which can be used to improve one’s game and ultimately one’s enjoyment. The 3Bays GSA Putt system is one of these systems, focused entirely on the area most amateurs can improve the fastest, putting.


3Bays GSA Putt is a small device which attaches to the end of the putter grip. Inside is an accelerometer which captures movement data and transmits it to a smartphone or tablet via a Bluetooth connection. In the mobile device is a very cool application which takes that putting stroke data and processes it, showing the player all sorts of great statistics. The data can be stored and compared for consistency, and even played back in real time or slow motion to give the golfer the opportunity to see what his/her putting plane or line really is.

The following statistics are tracked by the GSA Putt:

  • Tempo (including backswing, downswing, total)
  • Face angle throughout swing
  • Attack angle
  • Impact speed
  • 3D swing path (horizontal and vertical swing path shown individually)
  • Swing path distance

Along with the features above, the software allows the user to save swing sessions and view later. “Best swings” can be marked and are used to compare other swings for consistency.  In the image below you can see my “best swing” in blue and the current swing in white.  Fairly consistent.

Below is a video showing that latest stroke as shown by the application:


Setting up the unit to work with a smartphone is fairly easy.  You put the unit on the end of your putter, download the application from the Google Play Store (Android systems) or the iTunes Store (iOS systems).  Then follow some simple instructions to connect or pair-up the GSA Putt with your device.


This unit can be used even at home or the office when practicing putting on the carptet. No need to go to the golf course to work on your putting. The benefits of seeing one’s swing path and all of the individual statistics are fantastic. Many putters try to putt “stright back and straight through” but I do not. I use more of a Ben Crenshaw “swinging gate” stroke where the putter goes back inside the line, closes at impact, and then on the follow through goes back inside the line. You can see that swinging gate in the images and video. The problem with a stroke like that is making sure the putter face is square at impact, and you can see that I can be 1-2 degrees open at impact. That’s a push. By practicing and looking at my stroke data in the GSA Putt application, I can make sure my putts are all starting out on the proper target line.

In my opinion the most important stats tracked are the face angle and the tempo. My tempo looks good. I bring back the putter slow and accelerate through the stroke, thus the longer backswing time of .88 and shorter downswing time of .35. If those numbers were the opposite that would be very bad, as the backswing would be a quick jerk and then the putter would decelerate through the impact area, which is very bad.


Don’t buy a new putter to fix your putting issues or improve your putting. For the same cost of a nice new putter (under $200) you could pick up a 3Bays GSA Putt putting analyzer.

Yesterday I posted the first look of the 3Bays GSA (golf swing analyzer) Pro.  It is a small bluetooth device which attaches to a golf club and sends data to a smartphone or tablet running iOS or Android.   The smartphone/tablet contains software which analyzes the swing data and produces all sorts of useful graphics and technical data on the swing.

3Bays also has a putting analyzer called the GSA Putt. Like the GSA Pro, the Putt unit logs lots of great putting stroke data and displays it on the smart device (2nd image).  Below is the sensor unit attached to my recently cork gripped putter.

Weather permitting I’ll be working on both my 3Bays GSA Pro review and 3Bays GSA Pro Putt review and posting as soon as possible. Stay tuned.

I can’t wait to see how the new 3Bays GSA (Golf Swing Analyzer) Pro handles my dual chicken wing granny over the top epileptic seizure massive weight shift outside in but clubface square mega steep golfer’s elbow causing golf swing.  The GSA Pro is a device that attaches to the end of the golf grip and through bluetooth sends swing information to a smartphone or tablet.  That information is then used to show swing data which is useful for the golfer.

It is awesome to see where technology has gone with regards to things like this.  10 years ago a swing analyzer might have cost $30,000.  Now a better system is under $199!

I’ll be starting up my review process soon. Stay tuned for the full article.
