Looking to find information on lap counting timimg systems. Years ago I used to race and we had rechareable transponders that hooked to the cars. There was a counter that the cars ran under at the start finish line and it would give lap times and lap number. THis system was hooked to a computer and we could print the results and times of each race. I think that it would do 10 cars. Any ideas on who makes this kind of system? Thanks Chuck
