I was wondering how you guys did it. You must have a good organisation to count 90 x 10 laps, but I guess they are not all out on the track at the same time so not quite as hard as it sounds.
Unfortunately the proven systems aren't cheap! I looked into it again last year as some of our transponders were approaching end of life. There seem to be just two systems that are widely used for this type of thing, a the costs were similar, so we just spent a few hundred on 5 new transponders and stuck with what we had.
