GSA PRO

Great tool or golfers looking to get better, but please allow us to customize which data points to show on the home screen. I would like to see some sort of attack of angle or launch angle data points, and multiple clubs ie (multiple Drivers or Fairway woods) to track and compare witch is the right club. Shaft length is customizable but I would also like to see customizable loft options. All in all a good app; No Bluetooth issues, did get 1 error out of 40 swings using my iPhone 5.

App does pair with IPhone 8 Plus

I had just purchased the GSA Pro and recently got an iPhone 7. After reading these reviews I fully expected the Pro not to work with my new phone. However, that was not the case. After charging the little unit that slides into the grip and downloading this APP, I followed the instructions for Bluetooth connection and it found it immediately, no problem. I stuck sensor in my 7 iron, went out into my snowy yard and waited for constant blue light. Held club in that position for 2 seconds and swung. Blue light then blinked indicating data transfer to phone and sure enough, there it was. I did 2 more swings with no problem. Video and data of all swings there. I also signed up on 3 Bay Cloud and my data was synced to their site as well. I'm only 3 swings into this thing but it seems really cool and surely working as advertised. I don't know if swing speed and all is accurate but as other reviews state, the tempo and relative speed increase or decrease should help improve your swing, and it definitely showed if I had an inside or outside path. I gave it 5 stars to help overcome the single rating. It may not have worked in the past but 3 Bays seems to have addressed this. Seems like a super cool little device.

I purchased the iPhone version today. With the first one not working and a return to the store to exchange it, I finally got one that worked. I ran some tests and the device itself seems to work well. No failed readings yet. The software however is not up to par just yet. One major failing is that it does not allow you to flip the compare swings, so as a left hander I cannot compare my swing to the pro swings provided which are both right handed. A major bit of functionality which has been left out. I contacted their support who contacted me within a day and this missing functionality is coming in an update. Some other functionality which is missing but in competitive products is the ability to pan around a swing giving more than the current 2 views. It also only comes with 2 pro swings and no lefties are included. The backswing and downswing are also difficult to distinguish and the arrows on the lines are not much help. Being able to change the color of the downswing to a different color than the backswing would help significantly. I give this 5 stars for customer support and 3 stars for the software which I'm sure will improve over time if their great customer support is anything to go by. I will be testing the device against a Trackman soon but initial thoughts are that it will be in acceptable tolerances so I'd rate it a buy.

Just got my GSA device yesterday and tested it out a little. This thing is great and will add so much to my practice sessions giving me real-time feedback on my swing. That being said, I have a few suggestions for the developer to make it even better: 1. Add more pro swings to compare against. It's very valuable to see your swing arc overplayed with someone else's. Having more options would be even better. 2. Allow for adding notes and/or changing titles of saved swings. I can see it getting a little confusing after adding several swings to pick apart which was what. If I could have an instructor swing it and save that as separate from my swings somehow that was easily recognizable it would be great. 3. Make native for iPad (iPhone 5 for that matter) to give us more screen real estate and provide more info on a single screen.
