I guess I don't know the rules that well I thought part of the reason smart phones were not legal for gps was they provided a compass app. So he had a compass and a calculator, interesting. Thanks for the info Rick

In 2004, the year Scott won THE PLAYERS Championship (with a short putter), he ranked No. 1 on TOUR in strokes gained-putting.
With the broomstick he was Adam Scott's strokes-gained putting ranking the last 6 years: T102 148 143 186 180 178.......not sure why he went to the broomstick.
You are willing to bet he will do worse than those rankings for the last 6 years in @Rick Martin's comment with "a broomstick"? You might lose that bet even if he putts like crap.
I'm willing to take my chances.
Using a legal putter AND playing on Sunday? I feel my chances are outstanding!
Don't quote me on this, but they're usually not illegal unless they ONLY look at yardages. But most apps have Club selecting tools and other illegal tools. Tournaments reserve the right to ban whatever they want, and the PGA bans rangefinders. That's why you only see the yardage books, and other analog devices like compasses.
