Inconsistent ball compression = Inconsistent player performance

Warren, Michigan / PUBLISHED: December 6, 2023 – Rimac, a division of the Proform Company, announced plans to exhibit at the 2024 PGA Show, Jan. 24-26, 2024, in Orlando, FL. Rimac will introduce the Rimac® Golf Ball Compression Testing Device, setting today’s standard for measuring golf ball compression and giving golfers long-overlooked information critical for consistency, even when putting and chipping.    

How critical? Critical enough to invite the dreaded 3-putt! If a low-compression ball that falls into the hole 11’ away is swapped out for a high compression ball, the high compression ball may stop nearly 2-1/2’ short! Even if the force of the strokes is identical. To demonstrate the importance of compression, visit and watch the video.


Low-scoring golfers exhibit very consistent strokes, achieved by spending hours on the driving range, in simulators, and on practice greens so they can hit the shots they want on the course. In addition, such golfers gather helpful information as they play, noting the wind direction and speed, the speed of the greens, and measuring yardage distances. Moreover, they may invest in drivers costing $500 - $800, sets of irons running $1,500 - $2,000, and putters which may cost $400 - $600.  On top of this, they may invest in range-finders for $300 - $500 and golf GPS watches for $700, taking elevation, temperature, air pressure, and humidity into account.  

Despite all this, golfers have only a vague idea about the most essential information: golf ball compression influences the outcome of every stroke…putting, chipping, fairway shots, and driving.  

When it comes to compression, golfers know little more than what’s printed on the box:

  • “Soft”
  • “Softer”
  • “Soft Feel”
  • “Softer Feel for Faster Compression”
  • “Soft Feel Long Distance”
  • “Longest Ball with Soft Feel”
  • “Tour Performance with Soft Feel”
  • “Responsive Control and Very Soft Feel”
  • “High Ball Speed & Control with Very Soft Feel”
  • “Lowest Flight, Lowest Spin, Softest Feel”
  • “Longer Distance, Even More, Greenside Spin and Control and Softer Feel”

Golfers don’t know that even balls in the same box typically have different Rimac Compression measurements, often varying by 10-15%; that the average compression differences between models may be significant; that with the Rimac Compression number, they can see how the models offered by one brand compare with those of another brand; and that ball manufacturers may change a model’s compression from year to year to claim “new and improved” performance.

By using the Rimac Compression Testing Device – 19 lbs. of precision instrumentation -- a golfer can be sure of the consistency of the balls selected for play, sort them to match, and can make adjustments for inherent differences, just as may be done for wind speed and direction, elevation, and many other factors – recognizing that ball compression influences the outcome of every shot from the first drive to the last putt

At the PGA Show, the Rimac Golf Ball Compression Testing Device will be available for pre-order, with limited quantities available immediately.

Rimac Demonstrations

Demonstrations will be ongoing at Stand #1 adjacent to the putting green inside the exhibit hall, Stand #3418 in the Emerging Tech section, and the device will be displayed in the New Product Zone.  Attendees are encouraged to bring their own golf balls for testing.  

About Rimac Golf

RIMAC® has been the leading brand name in automotive valve spring compression testing and calibration since 1930, and the technology underlying its original patent remains in place today because RIMAC® devices are easy to use, durable, and accurate. For nearly a century, millions of racing engines have relied upon the RIMAC® brand for winning performance by ensuring every valve spring provides the specified amount of pressure. Now, this precision technology has been adapted to golf ball compression testing:  if the device is good enough for testing a $150,000 racing engine, it’s good enough to test a golf ball, and it’s essential for players with hundreds of thousands of dollars sometimes decided by inches.  With Rimac, you can assure yourself that the golf ball you select for play has the compression you expect – consistently.

For many years golf ball compression has been defined by a range that has typically run from about 40 to 100, representing 0.040” to 0.100” on a micrometer, resulting from compressing and deforming a golf ball only 1/10”.  For more real-world readings, the RIMAC® device compresses golf balls more than ¼” to reflect better the compression during actual play, and to synthesize better all the core layers and the cover material with which manufacturers manufacture their balls.  In the end, whether a golf ball is “2-piece” describing the ball’s cover and one material comprising the core, or “5-piece” describing the ball’s cover and a core that appears to have four layers, the whole combination boils down to one key number: the Rimac® Compression Number, which for more many shots, including every putt, will have more influence on the outcome than spin rate, ball speed, and smash factor…all of which are affected by the ball’s compression, which is the number that every golfer needs to know so that strokes can be adjusted accordingly, and balls selected knowledgeably.
