Optishot calibration made easy.. sort of

[FroggerGolfer]

Read many of the difficulties with optishots calibration, looked at the process and wondered how in the world do they expect me to hold it perfectly square, 10' closed and 10' open. Well, spent $6 on some wood and hardware, grabbed a digital protractor and set up a CFL lamp and calibrated fairly easy.

Because this was a rickety wood setup, it wasn't perfect, but led me to believe optishot is still pretty darn accurate. I sampled a few clubs, out of around 40 shots, the optishot was around +/- 1 degree around 80% of the time. The rest of the time I believe it was mostly variance in my swing rig. It did have some wobble to it. A handful of the time the sensors would read almost total opposite, yet the ball performed as expected. Something I measured at 10 degrees closed would show the ball path of a 10 degrees closed as the ball would track in the same exact spot as the last 40 balls, yet the screen would say something like 6 degree open. Quite odd. It was the exception though, only something like 3 balls out of 40.

Overall, once the user variable was removed, I found the optishot readings to be quite accurate.

To anyone having difficulty with shot reading, or calibrating, I suggest taking a couple hours to remove the human element.

For just calibration it is enough to draw lines on a sheet of paper at square, 10 open, 10 closed and manually push the club through. No need for speed or actual swings.

For testing you rig looks good. I did something similar years ago with similar results. The Optishot does OK when setup properly, the biggest problem is inaccurate ball flight display. But for raw club data it did fine, especially when on the range using the spreadsheet data results where you can delete the outliers.
