PC Tree Pro is a 32/64-bit Windows program and is the ultimate drag racing Practice Tree for your computer. Designed to improve your driver reaction time (RT) and the only drag racing practice tree with Cross-Talk! Family Software owner and drag racer, Bob Kodadek, developed the very first drag racing Practice Tree, PC TREE in 1985 for the Commodore 64 computer and then in 1987 for the IBM PC and compatible computers. There have been many drag racing practice tree imitations of PC TREE thoughout the years in both software and in hardware devices. Supposedly, the sincerest form of flattery! However, rarely are imitations as good as the original and usually just a quick way to make a buck. In fact, many of the software imitations are not technically accurate at all. The timing system developed by Bob Kodadek has always been accurate to .001 of a second on every platform. The new PC Tree Pro has all the functions of an NHRA or IHRA National Event Tree (Compulink Timing System) and is just as accurate.

Functions include:
Save Mode & Options - This function will save the current Practice Tree Mode and all selected Options.
Counters, Averages, Win Lights, and Scoring
