Our ball machine is now available for use. It is kept in the clubhouse and there have been two briefings about its use. Some members have already received a key to access it; others of us will be receiving a key soon. There is a manual left with it. Please look at this! Spinfire_Pro2_ManualFor your convenience, here are three screenshots about changing the settings eg for elevation (how high over the net the ball is sent). I think that the ball machine will retain the settings last used, so if a player much better than you used it last, then you might need to change things!
