1983-1999 | PRGR Official Site

1983

PRGR proposed a theory on head speed (H/S) that defined the standard for the power of a golf swing. This theory is now axiomatic in the world of golf on a global scale. This is when PRGR began to craft golf clubs no longer based on instinct and experience but by taking a scientific approach from several perspectives.
Also in 1983, the launch of the PRGR BALL golf ball series allowed PRGR to make its debut in the golf industry. Using the concept of "providing golf balls to match different head speed levels," PRGR introduced a wide selection of golf balls designed for different club head speed levels, such as the M-37 and M-40.

1984

PRGR held a head speed measurement event that attracted 20,000 participants.
In the same year, PRGR introduced the M-1 and M-2 drivers using carbon heads in an era when drivers were made of persimmon.
At the same time, PRGR introduced the CT series of easy long and controllable short irons designed by club number.

1986

PRGR launched the μ-240 Driver with the concept of a driver that can accelerate head speed. The new driver was recognized by the market as an innovation for using carbon reinforced plastic (CFRP).
When the shaft length of 43 inches was the mainstream, PRGR was the first to introduce to the market a lightweight, long (44-inch) driver.

1988

PRGR developed the golf club set "M-30" that was exclusively for female golfers as it made best use of the characteristics of ordinary female golfers, who have less power than male golfers. The muscular strength of an average female individual is about 60% of that of a male individual, and the average head speed of female golfer swings is 27-30 m/sec. PRGR analyzed, among other things, the muscular strength, H/S level, and swing pattern of average female golfers and devised various ways including materials, design, and manufacturing processes to increase the flight distance and make it easy to hit, as well as to clarify the difference in flight distance between each club. This "M-30" has now evolved into "SWEEP."

1992

PRGR introduced the BENT carbon head driver with a bent neck.
It was the driver friendly to golfers, aimed at alleviating slicing problems by moving the axial line of the club shaft more toward the inside of the head.

1993

PRGR launched the DATA series developed by applying the unique REVERSE theory that when the club head available in the market those days, many of them had a higher center of gravity is turned upside down.it will become a club head with a lower center of gravity. The DATA METAL WOOD (nicknamed Silver Metal) drew much attention from golfers for its innovative design.

1994

PRGR introduced the DATA WOOD REVERSE SD Titanium, a driver (nicknamed Red Titanium) that was ultra light and had a large head made from titanium.
The brand also introduced the DATA601 forged cavity iron series. Under the concept of "easy-to-hit long irons and easy-to-aim short irons," the series was designed by using a uniform center of gravity across all the irons. It fascinated many golfers (centered on advanced players) and was later recognized as a masterpiece iron series.

1996

PRGR launched its new ZOOM brand to lead the dawn of utility clubs.
The ZOOM i in particular was recognized as an excellent iron utility club, becoming very popular, even among pro tour golfers.

1997

PRGR signed an endorsement agreement with Corey Pavin, a leading American professional golfer, who won the 1995 U.S. Open.

1998

PRGR introduced the REVERSE Titanium Type 300 driver (nicknamed Silver Titanium).
It combined a large head and a long shaft and it ruled the world, leading to 90,000 units sold. It was the driver heralding the advent of the large head era.

1999

PRGR introduced the REVERSE Titanium Type 310 driver (nicknamed Red Power). Though being a 47-inch or long model, it offered a high-trajectory and long flight distances achieved through the tenacious research on high-repulsion club development by of PRGR's scientists. Pro tour golfers were compelled to use it as well.
