Why are pros using laser rangefinders, GPS at the 2024 PGA Championship?

The PGA of America announced back in 2021 that it would allow the use of distance-measuring devices in its three professional major championships – PGA Championship, KPMG Women’s PGA Championship and KitchenAid Senior PGA Championship – starting that year.

The devices made their first appearance at the 2021 PGA Championship at Kiawah Island Golf Resort’s Ocean Course in South Carolina.

“We’re always interested in methods that may help improve the flow of play during our Championships,” said Jim Richerson, then the president of the PGA of America. “The use of distance-measuring devices is already common within the game and is now a part of the Rules of Golf. Players and caddies have long used them during practice rounds to gather relevant yardages.”

The PGA of America became the first major body to allow the devices in all its premier professional events. There had been speculation for years that such devices might help speed play, as players and caddies don’t have to walk off yardages to sprinkler heads and other fixed positions.

The United States Golf Association’s Rules of Golf have allowed the use of laser rangefinders and GPS devices in casual play and tournaments since 2006, but a local rule allowed a tournament committee to ban such devices. At elite professional levels of play, the devices still have not been embraced for competition rounds, though they have been allowed in the U.S. Amateur since 2014. They are still not allowed during competition rounds at PGA Tour events or at the U.S. Open and British Opens.

In keeping with Rule 4.3a (1), the devices allowed can report only on distance and direction. Devices that calculate elevation changes or wind speeds, or that suggest a club for a player as well as other data, will not be allowed.

The devices aren’t new for the pros, many of whom already use laser rangefinders and GPS in practice rounds.

Many laser rangefinders provide information on elevation changes and “plays-like” distances. Most of those devices come with a switch to turn off such information, but many elite players opt for devices that do not provide elevation and other data as a precaution against forgetting to turn off those functions.
