After a lot of reading about ball balance (which I never thought about) from salt water marking to the Check-Go, I decided to get the product. Testing many many balls to see how this product reacted was fascinating! I found that no matter the manufacturer of the golf balls, most were not balanced perfect (using salt water or the Check-Go proved it).

Now I don't like buying expensive balls because I just can't justify spending dollars for a ball versus pennies for a good comfortable feeling ball. Less crying when I lose a cheaper ball versus a $6 ball. I have played expensive balls and the Wilson Smart core balls, which I enjoy and found very little difference in play and comfort (I shoot mid to high 80's). So testing the balance between different golf balls was so interesting.

Using the saltwater test indicated that about 90% of the balls were off balance and that the same spot would come to the top, if it didn't it showed the ball was balanced. Crossing this information over to the Check-Go showed the same thing, but lined with the "Equator" of the ball. The spot I marked from the first try with the Check-Go came back to the top. A small percent of the balls the marked spot went to the bottom, but the equator was the same. A smaller percent of the balls never lined back up the same, indicating the ball was a perfect balanced ball. Which matched the saltwater test.

What I found interesting, was that the alignment between the two different methods very seldom showed the same location and were different by several degrees. Not sure which is better at this point, but I sure am looking forward to spring to test it on the course. My wife thinks I am crazy, but she doesn't play golf. LOL

The science behind "balance" makes sense to me, if you think about the weight being off some and the process of high speed manufacturing. How many putts are missed by just a very small amount? Not saying it will make me a scratch player (oh but that would be nice), but if it helps me make 4 puts more in a 18 hole round, it will be worth it.

Bring on Golf season!!!

works great. works better than the first generation of check-go that i own. marks lines in the middle of balls consistently, something that first generation didn't do. consistently spins ball without wobbling them out of the spinner, also something that first generation didn't do.

I wish the science proved the theory but it does not. Put already marked balls back for a second and third spin and all the lines are different. I bought a plain ball marker and lined up my putts to watch the line go end over end perfectly without balancing them at all. Wow. Expensive balls are already balanced! Whodathunk!

It is a great way to find the spin balance equator of a ball. I have modified mine to use a Sharpie. Obviously part of their revenue stream is selling additional proprietary markers that only fit.

Okay, I bought this handy device, unfortunately the pen that came with the Check-Go Pro does not last long but the device itself works well. If you already have the Check-Go Pro than you may want to buy these "Promarx Permanent Markers" as the tip on these pens will work nicely with the base component. ("Promarx Permanent Markers , Fine Point, Assorted Colors:"). Note, the vendor for this device no longer provides replacement pens! Amazon sells these pens as noted above and the cost is reasonable.
