The 15th hole is 181 yards with bunkers to the left and water along the right side.
The fans won't be able to put the flag wherever they want. Haigh said the 15th green has a number of options for pins, and he has selected four from which the fans can choose. They will not affect where he sets the hole location for the other three rounds.
"They will be four not used during the week," he said. "It's a green that does have plentiful locations because there's water all the way down the length of the hole, and three bunkers. There isn't an easy one. It's difficult. And it's sheltered by a tree on the left, so the wind will influence the shot. It will be fun."
This won't be like throwing darts.
When fans go to the website, they can click one of the four hole locations to get a visual presentation, along with the audio of Nicklaus explaining the differences in how it could affect the shot.
"The chance for golf fans to interact with the PGA Championship and play a role in shaping the outcome of the final round fascinates me," Nicklaus said. "It's like being able to call the shots during the fourth quarter of the Super Bowl. ... I believe this new concept will serve as an exciting hands-on learning experience for golf fans, and I'm happy to be involved."
Haigh has been in charge of setting up the course for the PGA Championship, Senior PGA and Ryder Cup since 1989.
A sweepstakes will be held in conjunction with the contest, with one prize a chance to get behind-the-scenes experience at the PGA Championship next year at Valhalla.
