"RaceChrono Pro is the gold standard for data logging. As someone who obsesses over telemetry, the ability to sync my external 10Hz GPS and OBD-II data has been a game changer. I've used it at circuits across the U.S., and the predictive lap timing is incredibly accurate, helping me shave seconds off my personal bests by seeing exactly where I'm losing time in the corners."

James Miller, SCCA Club Racer

"I've tried dedicated hardware loggers costing thousands, but I keep coming back to RaceChrono Pro. The video overlay feature is seamless and looks professional when I share my hot laps on social media. The track library is massive—I've never been to a road course that wasn't already in the database. It is the most reliable tool in my track day kit."
