The 3Bays GSA Zone is an easy-to-use, accurate swing analyzer. May require professional help to get the most out of the data.
A few years ago, on-club swing analyzers were the hottest gadgets in golf. New devices were popping up left and right, constantly adding new features and improving accuracy. While they’re no longer the subject of as much chatter, these devices can still provide important feedback to help golfers improve their swings.
The latest such device is the 3Bays GSA Zone. This is an update on the popular 3Bays GSA, the lightest and smallest sensor on the market. In this review, I’ll let you know if this is a worthwhile tool for improving your game.
Set-Up & Ease of Use
Setting up the 3Bays GSA Zone is quite simple: download the free app (available for iOS and Android devices), pair the sensor with your phone, and get to work.
When you turn on the sensor, your phone will automatically prompt you to open the 3Bays app. The instructions say that the device needs to be held still before swinging, but I found this isn’t really true – as long as you don’t go directly from an exaggerated waggle to your swing, you’ll be fine.
The data from each shot is uploaded and displayed on your phone within 2-3 seconds. The app itself is easy to use, but not totally seamless. I spent a couple minutes poking each of the buttons to figure out what they did before I felt like I could easily and effectively navigate to the things that I wanted.
The 3Bays GSA Zone provides a good amount of data. As you can see in the screen captures below, the stats are: Top of Backswing position, Shaft Lean (at impact), Face Angle, Club Head Speed, Consistency, Tempo, Swing Path, Carry Distance, Back Swing Time, and Down Swing Time. In my opinion, it’s neither too much nor too little, and the stats are pretty accurate. Face Angle and Club Path are displayed not as specific values but on a continuum from Closed to Square to Open. I think that’s a smart move because it avoids the question of perfect accuracy, which is nearly impossible for such devices to achieve, and instead focuses the golfer on the broader concept of keeping the face and path within certain ranges.
One issue these devices always have to wrestle with is how much instruction to provide. On one extreme would be a device that says, “Your swing is wrong, it should look like this.” The other extreme would be a device that gives you data without any instruction about whether your numbers are good or bad. The 3Bays GSA Zone is much closer to the latter extreme. With the exception of one set of PGA Tour numbers, there are no suggestions about what your numbers should be. I do tend to prefer this approach- not everyone should swing the same way – but it does bear mentioning that players without a strong understanding of the swing may want to use this device in conjunction with lessons.
In addition to the stats, 3Bays GSA Zone gives you a 3D image of your swing that can be viewed from any angle. For most players, this is the most powerful piece of information. If, for example, you have a severely “over the top” swing, you can see that and easily work on changing it. On every swing, you can see whether or not you were successful in making your change.
All in all, I think 3Bays GSA Zone provides enough quality data that it can help you to make a swing change or dial in your swing.
There are a number of elements that work in favor of the 3Bays GSA Zone having good longevity. First, it’s tiny and easy to use, meaning that you can keep it in your bag and set it up quickly when you want to use it. I think that the 3D image is a powerful tool, and I can see players checking out their image and stats when things start to go awry.
On the other hand, there’s nothing particularly “sticky” or addictive about using 3Bays GSA Zone. It’s a good device, but there’s no inherent feeling of success or failure on each rep as there is with some other training aids.
Ultimately, the life span of the 3Bays GSA Zone will depend on what you’re using it for and your practice preferences.
If you’re in the market for an on-club swing analyzer, I think the 3Bays GSA Zone deserves to be one that you consider. It’s light, small, and easy to use, and the data that it provides is accurate. The key in purchasing this or any other sensor is making sure that it provides the information you want and that you understand the data.
