The ball must even have the basic properties of a spherically symmetrical ball, usually that means that the ball itself have to be spherical and will need to have a symmetrical arrangement of dimples on its surface.
Additional rules direct players and producers to different technical documents revealed by The R&A and USGA with further restrictions, comparable to radius and depth of dimples, maximum launch velocity from test equipment (typically defining the coefficient of restitution), and most complete distance when launched from the test gear.
In normal, the governing our bodies and their regulations seek to offer a comparatively degree playing field and preserve the traditional type of the sport and its gear, whereas not utterly halting the use of new technology in equipment design.
Until 1990, it was permissible to make use of balls of less than 1.68 inches in diameter in tournaments underneath the jurisdiction of the R&A, which differed in its ball specifications guidelines from these of the USGA.18 This ball was commonly referred to as a “British” ball, whereas the golf ball approved by the USGA was simply the “American ball”. The smaller diameter gave the participant a distance benefit, especially in high winds, because the smaller ball created a similarly smaller “wake” behind it.
