Since 2001, The PGA Tour's
ShotLink has been
collecting data on every shot by every player at every tournament (about 32,000 golf club swings for
each four-day PGA Tour event, according to
USA Today).
The system measures where golf balls start and land, and all the ground covered in betweendriving
distance to the fairway, how well each player putts from different measurements on the green and much more.
ShotLink uses a combination of high-tech lasers and PDA-toting volunteers to get all that data, which is
used by TV broadcasters and fans on PGATour.com or those accessing via mobile applications.
