Technasonic Check-Go Pro Sweet Spot Electronic Golf Ball Liner

Each ball has its own unique Sweet Spot. Hitting it will increase the distance and accuracy of your drives while reducing the chance of hooks and slices. Check Go Pro finds any golf ball's "true balance equator" in 30 seconds, improving a ball's playability off the tee and when putting. Check Go Pro's patented spin-balance technology improves game performance by balance-calibrating any golf ball before play. While spinning at over 10,000 RPM, this amazing device finds a ball's center of balance and draws an equator along it. This balance equator represents what is referred to as the "Sweet Spot" of any golf ball. By playing aligned with the balance equator, you will hit straighter and farther while reducing hooks and slices. Nearly every golf ball manufactured is imperfectly balanced. Even the very best golf ball can and will perform substantially better when played on its true balance equator. Play better golf with Check Go Pro.
