The Check-Go Pro has helped many golfers improve their game.

Don't just take our word for it. Read what some of our customers are saying.

“Love your little gadget. Must have shaved at least 5 strokes from my game. One thing though, where can I purchase replacement markers for the Check-GO? I am 68 and my handicap is 23. My two oldest sons got me started when I visited them 10 years ago, in North Beach, MD. and I have been hooked ever since.”


“I had a hole in one on a 125 yard, par 3 on August 14; the Check-Go Sweet Spot Finder was a gift from my husband on August 1… thanks for the thrill.”

-Candace F. Longmont, CO

“I believe knowing where the sweet spot is and marking it has helped me add 20-25 yards to my shots. I use the equator line in my teaching. . .showing the student if the ball is stroked properly the line will remain straight, if not, the line will wobble… Thanks for this great little device.”

-Walt P. Golf Pro

I will continue to play with the Check Go marked balls for the next few months and I expect to lower my scores by 2 to 4 strokes per round. The boys at the club skins game are in for a few rough days until I can get them to buy one for themselves, thanks for a great product.

“We at DV Golf are totally involved in our custom fitted client’s golf game and we were especially happy to recommend the Technasonic Sweet Spot Finder to them. Our own tests consisting of tee shots and putting made us eager to put this machine in our line of products that we insist our client’s have to help them improve their scoring. Professionally Fitted Golf Clubs AND The Technasonic Sweet Spot Finder, what a combination!”

“It was a pleasure to talk with you today and learn for certain that there is no objection by the USGA regarding use of the Check-Go device. I must admit, it does seem a little like cheating when I play with other golfers not yet using it.”

“I have been using your Check-Go Sweet Spot Finder for the past two months in Florida, and I am amazed at how well it has improved my game off the tee and especially on the green. The idea of dynamically finding and marking the natural spin axis of each ball for better alignment and truer ball direction has been more successful for me than than trying to select the best brand of golf ball. I’ve already dropped two strokes in handicap. Thanks for bringing advanced technology to bear on the game of golf! If I can help it, I won’t play with a ball that isn’t marked by your little device.”

I just wanted to pass along a quick note to inform you that the Check-Go units have become a “big hit” for my daughter’s high school golf team, La Reina H.S. in Thousand Oaks, CA. The kids are so convinced that the units give them a competitive advantage that the coach has made it mandatory for each player to mark their ball prior to the match. The school is ranked #1 in the county, so their opinions are not hollow, and have translated into great play on the course.

Aside from the check-go units, the two piece golf balls we purchased have also been a roaring success. The kids feel the balls give them greater distance, and every one of the balls is perfectly marked so the kids ensure themselves of proper balance when putting.

The coach was getting a bit concerned when his supply of golf balls was dwindling this past week….hence the additional 5 dozen ball order I placed yesterday. You make a great product that truly works. Keep up the great work!

Received the Check-GO Pro and wanted to let you know it is a vast improvement over the Check-GO. Much easier to use and marks the ball exceptionally well. I’ve been using the original one for about 2 years and despite it’s shortcomings, it was and improvement over my old methods of marking the ball.

The Pro edition is really an improvement, I actually showed it to the local Golf shop who had not seen the product yet. I’m guessing I made believers of them. It’s really improved my alignment in both driving and putting the ball, good product in the vast wasteland of golf ‘stuff’ that ends up collecting dust. The Check-GO Pro will not.
