DeChambeau allowed to keep using controversial compass

Bryson DeChambeau takes an extremely analytical approach when dissecting a golf course, a method that came under scrutiny when he was spotted using a compass (the drawing tool, not the navigational instrument) at this past week's Travelers Championship.

After consulting with the United States Golf Association, the PGA Tour announced Monday that DeChambeau could continue using the compass because the rules do not address its use ... for now.

"There is no clear precedent on the use of a compass in this manner and it is not currently prohibited under the rules of golf," the Tour said. "The USGA is reviewing the matter, with our feedback, and is expected to make a ruling on its conformity with the rules soon."

DeChambeau uses the tool in his greens book to more accurately determine hole locations.

"I'm figuring out the true pin locations," DeChambeau said. "The pin locations are just a little bit off every once in a while, and so I'm making sure they're in the exact right spot. And that's it."

DeChambeau - who majored in physics - has earned the nickname "The Scientist" for these sorts of antics. He uses single-length irons, calculates break in the greens, and takes air density into consideration when determining yardages.

With his recent win at the Memorial and other impressive finishes, people are paying a lot more attention to the world's 22nd-ranked golfer.

"It's a compass. It's been used for a long, long time. Sailors use it," said the 24-year-old. "It's just funny that people take notice when I start putting and playing well."
