Sorry about that, I was talking about a type of Gyroscope; by spinning the ball at high speed you can locate its balance point and mark it with a line or a dot.
The one I use is made by Technasonic but I'm sure there are others; they can be found in most Golf stores (PGA for sure) and on-line.
Thanks, OK. I have one of these machines.
I thought maybe some new kind device had been devised to somehow 'scope' -- x-ray or calibrate or something -- the balls without putting them on the 'spin machine'. Thanks for clarifying. I've learned a new term!
