Help!!
I just bought a Stern STpro nib.
One of the sensors in the ball trough is misfiring. It thinks there is a ball in the trough when the ball is in play and it will end my turn. Or during ball save it will kick out a second ball because it thinks I have drained.
What do I do to diagnose or fix? I will see if this is covered by warranty Tomorrow . Any advice would help.
