Golf Shop: ASSORTED Magnetic Protractor

"Magnetic Protractor : This versatile clubfitting device yields accurate lie angle information. Have the golfer hold a club at address, attach the magnetic protractor to the shaft tip and read the exact lie angle. Check each club in the set before making new custom woods or irons. The magnetic protractor is also great for checking the lie angle of irons before and after bending them on a loft-lie machine."
