If you are running a tournament and don't have a PA announcer, you can still run AnnouncerSR on the computer running TournamentSR.  Just before distributing printed bout cards, change to the AnnouncerSR window and move the matches to the appropriate mats.

When wrestlers don't know which mat they've been assigned to, you can look at the AnnouncerSR window.  If you provide WiFi, wrestlers can find their mat assignments on their smart phone, tablet, or laptop
