Golf Shop: ASSORTED Magnetic Lie Demonstrator

"Magnetic lie indicator helps the clubmaker or clubfitter determine whether a player s clubs are fitted to the proper lie angle. Attaches magnetically to iron face at a dead 90° angle, so there s no guesswork; 15-inch rod indicates whether the player s clubs have the correct lie angle. Note: Not all types of stainless steel are magnetic; please check your clubs for magnetism first."
