Scottie Scheffler complains about new PGA Tour rule immediately after Rory McIlroy win

doesn't think the use of rangefinders will solve the issue of slow play at major tournaments. The American spoke out on the 's rule change just days after missing out to at .

The PGA Tour have changed their rules to allow the use of rangefinders for a trial period between the Masters and the PGA Championship. The devices are used to measure distances on golf courses to give players an indication of how far they are from certain points like the green, the flag or a bunker. Golf stars will initially be able to use rangefinders at six Tour events, with their first opportunity coming at the RBC Heritage, which gets underway today (Thursday).

Scheffler is set to feature at the RBC Heritage after finishing fourth at the Masters last weekend. The 28-year-old kept himself in contention for most of the final round at Augusta but fell away late on as the tournament was decided by a play-off.

to overcome Justin Rose as he won his fifth Major to complete a career Grand Slam.

The Northern Irishman is set to enjoy a break following his latest triumph and will miss the RBC Heritage. But Scheffler will be present as he looks to defend the title he won last year.

And commenting on rangefinders ahead of the tournament, last year's champion explained: "We've been using them at the PGA [Championship] the last couple years, haven't we? Is it going to help pace of play? Maybe a few minutes. Will it be anything significant? No."

Scheffler then insisted tournament pace would be quicker if golfers played in groups of two instead of groups of three.

He added: "This tournament, what affects the pace of play is walking the golf course. I think we're playing twosomes all week, so it will go from a five-hour round to maybe four hours or less.

"When you see the biggest changes in pace of play, it all comes from going from three guys to two guys in a pairing. It's just easier to get around the golf course.

"Also, the distance walking from green to tee is a big factor as well if you're going to save 15, 20 minutes off the round. This golf course is pretty simple in terms of getting around.

"I think the only way to have a significant impact on the pace of play, if you look at the average round time last week [at the Masters], Thursday and Friday you're playing in threes, Saturday and Sunday you're playing in twos.

"There's going to be a significant difference, probably over an hour difference in pace of play."
