GCC stones now have the latest technology built-in to them: Klutch Curling! Located between the handle and the stone, are sensors that provide curlers loads of delivery details including short and long times, amount of drift, and whether the release was pushed or pulled.
All current members of the GCC can access Klutch for free. Visit the GCC Klutch Curling page at http://www.curlingseattle.org/klutchcurling (GCC web site log-in required) to learn more about how to get started, practice drill ideas, and other great tips!
