PuttLink Smart Ball and Stimp Ball connect via Bluetooth, so ensure Bluetooth is enabled in your device settings.  In addition, location permissions will need to be allowed for certain features.

Our patent-pending technology uses light sensors to accurately calculate ball motion.  There should be no problem on outdoor putting greens from dawn to dusk.  When using indoors, a well-lit room is needed.  Natural light from a window will work as well.      

When ready to putt, place the ball on the putting surface with the PuttLink logo facing up and the alignment line pointing forward.   

This is a putting training device.  Do not hit the ball with a driver or another club that is not a putter.  This would most likely result in damage to the electronics and would not be covered by a warranty. 

Do not submerge the ball in water.  Normal moisture found on a putting green is not a problem.

The range of the Bluetooth connection depends on device type.  A phone placed on the provided stand will generally give a range between 10 and 15 feet.   A phone kept in a pocket will give a range of around 20 to 25 feet.  Following the putt is suggested for longer putts. 

If the ball goes out of range, a popup message will appear in the app.  Reconnect by pressing the connect button in the app.

The battery is currently not rechargeable.  We believe the battery will last up to 2 years or more and thousands of putts.  A one-year free replacement warranty is provided, and a 2-year replacement warranty option is available for $25.
