The hand that you wear the watch on depends on whether you are a left or right-handed golfer. If you play as a right-handed golfer then it must be worn on your left hand, and if you play left-handed then it must be worn on your right hand. The watch must be within 10cms of the tag when swinging the club, therefore it is essential that you do not wear the watch too high on your wrist.
By default, the watch is configured for right-handed players. This can be changed in ‘Settings’ on either the desktop or mobile apps. Your watch must be connected via USB or Bluetooth to change this setting.
