On August 18, 2003 a robotic test was performed
by Golf
Laboratories, Inc., an independent golf equipment
testing facility in San Diego, California.
The test was conducted to compare the difference
in the performance of golf balls hit off of a
regular 2-3/4" wooden tee to those hit off
a 3" Stinger "COMPETITION" golf
tee.
A Callaway Great Big Bertha driver with 10 degrees
of loft was used for the test and the robot swung
the club head at approximately 95 miles per hour.

The test results definitively proved the following:
-
The golf ball left the Stinger "COMPETITION"
tee 2 mph faster than the regular tee.
-
The golf ball spun an average of over 500
RPM less off the Stinger "COMPETITION"
tee than the regular tee.
-
The golf ball had a slightly higher trajectory
and carried farther off the Stinger "COMPETITION"
tee than the regular tee.
-
The total distance the golf ball traveled
hit off of the Stinger "COMPETITION"
tee averaged 14 yards farther
than a golf ball hit off of a regular tee.
|
The
USGA has determined that
"STINGER" Golf Tees are allowable
under
the rules of golf. |
