Callaway is the world's largest producer of golf clubs, a company founded in 1982 by Ely Callaway Jr., an avid golfer in his youth. In 1991, Callaway launched the Big Bertha driver named after the German long-range cannon, which ushered in the era of large club heads, and in the early 2000s, Callaway launched the CB1, HX, HX Tour and other golf balls, making Callaway's golf balls the second most used brand on the PGA Tour.
 
Callaway's R&D concept and production level are in a leading position in the whole industry. As early as 1996, Callaway recruited engineers from DuPont and Boeing to develop golf balls using aerodynamic principles. In 2016, Callaway partnered with Boeing to develop the XR16 driver, which was selected by British player Daniel Willett and won the Masters in the same year.
 
At present, Callaway's main products are EPIC FLASH and ROGUE series, priced at about 5000 yuan and 4000 yuan respectively, and each series can be subdivided into standard version, SUB ZERO professional version, STAR light version and STAR light women's version. While the standard version and the SUB ZERO Pro version are more suitable for male golfers with more strength, the two lightweight models of the STAR are made for weaker golfers, and it is recommended that female golfers choose the women's version, generally speaking, the shaft of the women's club is softer than that of the men's club, suitable for slower swing speeds, and the whole shot is lighter and shorter, which can make some compensation for the distance of the shot.
 
THE EPIC FLASH AND ROGUE DRIVERS ARE EQUIPPED WITH CALLAWAY'S SIGNATURE "JAILBREAK TECHNOLOGY", WHICH HAS A TITANIUM STRUT BUILT INTO THE REAR OF THE FACE TO REINFORCE THE CROWN AND BOTTOM OF THE CLUB, SO THAT THE FACE IS NOT PRONE TO DEFORMATION WHEN HITTING, THUS ENSURING FASTER BALL SPEED. At the same time, the crown made of triaxial composite improves the moment of inertia (MOI) of the clubhead, ensuring forgiveness and stability during hitting.
 
EPIC FLASH IS CALLAWAY'S FLAGSHIP PRODUCT LAUNCHED IN 2019. UNLIKE TRADITIONAL DESIGN PHILOSOPHIES, THE EPIC FLASH DRIVER RESULTED IN AN IRREGULAR WAVY FACE THAT CALLAWAY SAYS IS THE BEST SOLUTION THAT HAS BEEN SCREENED THROUGH MACHINE LEARNING AND ARTIFICIAL INTELLIGENCE SIMULATIONS. In practice, this design does effectively improve the rebound coefficient of the sweet spot, and the ball speed and ball distance can be significantly improved when teeing off, and the distance can be played at 266 yards in the actual test. In Golf Digest's 2019 Driver of the Year recommendation, the EPIC FLASH driver received a perfect score.
 
COMPARED TO ITS PREDECESSOR, THE OUGUE, THE EPIC FLASH DRIVER HAS A SINGLE-TRACK DESIGN WITH A BUILT-IN ADJUSTABLE COUNTERWEIGHT, ALLOWING GOLFERS TO ADJUST THEIR OWN PATH. AT PRESENT, THE PRICE OF THE ROGUE'S DRIVER IS ABOUT 4,000 YUAN, AND THE PRICE OF THE EPIC FLASH DRIVER IS ABOUT 5,000 YUAN.
