Anyone using a swing analyzer at home/on own (i.e. not trackman with a pro). I am looking at them, but not enough confidence in them to pull the trigger yet. I am seeing some reviews of Zepp Golf that are mixed, but would love to know if anyone is using Blast Golf, Swing Byte or 3Bays. 

Blast Golf or 3Bays look to make the most sense to me as the analyzer fits into end of club and likely has little to no impact on natural swing. 

I've tested a bunch of them Brewcee and unfortunately the feedback is not that great.  Most have very limited uses. 

The Zepp is interesting for looking at path of hands, etc but it did not captivate me enough to keep using it extensively.  I am still working with a demo to compare to radar based systems so I'll try and publish more on it when I have time to make full comparisons. 

The SwingByte2 was much improved over the original SwingByte in that the app improved with better aiming. Unfortunately reliability is an issue in regards to numbers.  Tests by a few fellow pros indicated the face angle readings could be off by as much as 27 degrees sometimes.  Often this can result in movement of the device on the shaft during the swing.  Gropper might be able to weigh in here as I believe he had one. 

I found it was hard for any of the gyro based systems to provide accurate #'s on face angle, path, and angle of attack.  A variance of 5 or 6 degrees in any of these numbers can make them useless to work with.  If you think your AOA is -3 and it is actually +3, that's a problem.  Same goes for FA and Path.   You might be able to just use it for comparison from swing to swing in concert with watching ball flight but not sure how confusing that might become. 

This becomes even more problematic for the devices located at the end of the grip when some of the key data they are supposed to be measuring what is happening in the clubhead.

At the lower price level if all you are looking for are launch #'s then the Ernest Sports systems are showing some promise.  The higher level ES14 (about $600) has proven to be quite accurate.  The older ES12 is still available and closer to $250.

It all depends what you expect from them...

They will all get better over time.
