Boomerang tool

Q: I understand that there is a tool that helps in stringing the Prince O3 racquets. Does it work? If so, where can I find one?

A: You are referring to the “boomerang” tool. It’s used to preserve string alignment through the top four O-Ports when stringing the crosses. Prince used to bundle one of these with each O3 racquet, but many stringers simply used the turntable brake instead of the tool. If your stringing machine has an effective turntable brake, and you can operate it quickly and easily, your stringing time will probably be lower using the brake. If, on the other hand, your machine has no turntable brake, or it doesn’t work well or easily, the tool is invaluable. USRSA members who need a boomerang tool can contact customer support at 760-536-1177 to have one sent free of charge while supplies last.
