ProCheck®, a new device designed for golfers who want to maximize distance by matching the correct ball compression to their swing speed, will be available to all golfers through Revolution Golf ( beginning Tuesday, September 25.

ProCheck® checks ball compression instantly and recommends the correct pressure for each golfer’s swing speed. Matching the right compression with a golfer’s swing speed can increase distance by as much as 10-20 Yards. In a study of 250 players conducted by the Brand institute Inc. on behalf of ProCheck®, 90% of respondents indicated there is a need for a product to check ball compression.

“A golf ball’s compression has a significant impact upon how far it will travel, with the golfer’s ultimate goal being to match ball compression with swing speed to achieve maximum distance,” said John Donahue, President of Golftek LLC, the company that manufactures ProCheck®. “We are excited to make ProCheck® available to golfers of all skill levels through Revolution Golf, the premier on-line source for everything golf.”

Donahue designed ProCheck®  after conversations with an avid golfer who complained that with the new, more durable covers, old tired balls still look like new but their compression has changed. Donahue put his master’s in mechanical engineering from the University of Massachusetts to work and developed ProCheck®.

“Callaway has long understood that compression plays a key role in optimizing the performance and consistency of golfers.   We at Callaway have tested the ProCheck® golf ball compression tester and found it to be an excellent tool for the consumer.  Its readings can help golfers determine the right ball for their game,” stated Jason Finley, Director, Brand Management, Callaway Golf.

The correct compression causes the ball to have the optimum degree of flattening at impact to create a trampoline-like energy transfer and greater distance.  When testing a ball, the accurate compression will quickly be displayed on the ProCheck® LED screen. Golfers with slower swing speeds (under 80mph) should use lower compression balls, while golfers with faster swing speeds (over 100mph) should use higher compression balls to achieve maximum distance. While new balls may have some compression variability, older balls or balls that have been exposed to extreme heat (e.g. stored in the trunk of a car) or cold weather conditions (e.g. stored in a cold garage) experience significant changes in compression.

The ProCheck® device, which was issued a United States patent in May 2017, rivals the top golf ball manufacturers’ highly sophisticated compression testing equipment. In laboratory tests, the ProCheck® produced the same compression measurements as a device costing tens of thousands of dollars that is commonly used in the industry.

About ProCheck’s Technology

The ProCheck® a highly sophisticated ball compression measurement  device uses proprietary technology to measure a golf ball’s compression. It has been proven that a golf ball’s compression has a significant impact upon how far it will travel, with the golfer’s goal being to match ball compression with swing speed to achieve maximum distance.

With balls being struck at swing speeds ranging from 70-120 mph, it was critical to develop a device that measures the force on a golf ball in an instant. ProCheck® measures the force over a selected time interval to get an accurate force value. ProCheck® has a high speed micro-processor that captures the force for a tested golf ball, processes the information and displays an accurate reading of its compression to the user.

Most modern golf balls are essentially made of a rubber-like substance (elastomers) and the forces required to compress the ball can change over time or with temperature.  ProCheck®’s accurate force measurement detects this change and displays this information to the golfer as bars on the LED screen.
