I'm in the process of opening a Dirt oval track and am looking for a lap counting system with transponders.. Does anyone have any info on these and which is the best to go with?

Thanks
Butch

Search on Ebay, Starting out go with the AMB system.

Yes,
rctimminng.com I beleiev that's the web site. Computerized system and transponders.

AMB is the industry standard for hardware. You have your choice of software. There are several different packages available.
