The Pro Screen contains all of a racer’s PRO TREE settings which include (pro tree) delay, throttle stop timer, and a time or rpm shift point setting. All of these settings are independent of the settings used in bracket racing. This means that a racer can run both Pro Tree and Brackets without having to change the settings in the unit. Switching back and forth from Pro Tree to Bracket Racing is now as easy as a touch of a button. All settings are retained in memory.
