Golfweek's Jim Achenbach is still elated about the USGA/R&A rules change on distance measuring devices.
The primary argument in favor of rangefinders and GPS systems is straightforward: They help speed play by allowing players to know yardages without hunting for distance plates or marked sprinkler heads.
Still waiting on someone to actually document this one.
Either way, the tours will likely never accept these because, well, they're vain and they don't want their players to look silly. For all of the talk of better athletes, there is something rather unseemly about these uh, jocks, pulling out a device and looking through it, then putting it back in their pur...err...I mean bag, before hitting a shot.
