The Tests
Green Keepers Inc. set out to make the longest playing tee in the performance tee category.  After 18 months of product research, development and improvements we tested the tee.  First a robotized test was conducted to see how the tee performed under perfect swing conditions.  The tee outdistanced wood by 3.9 yards

Encouraged by the results we went back to make slight improvements and setup the tooling for manufacturing.

Greens Keepers Inc. understands that not every golfer swings like a robot.  An independent research firm conducted a field test comparing the “4 Yards More” Prototype Golf Tee to wooden tees, using 10 golfers of varying abilities. 
  Each golfer hit 10 balls off of wooden tees.  After the ten balls
were hit, the research team measured and recorded each distance.  The driving range was cleaned.  Then each golfer hit 10 balls off of the “4 Yards More” Prototype Golf Tee. Again, the research team measured and recorded each distance.

The results were tallied and averaged, yielding a 4.2 yard difference in favor of the “4  Yards More” Prototype Golf Tee.

Averaging the Robot Test and the Field Test gave us an overall 4.05 yards greater distance over wooden tees.

Green Keepers Inc. is proud to present the latest in the Performance Tee Category. “4 Yards More” Golf Tees.
