What race directors say
"My compliments to your product and service. I have used RaceClocker for several events, and I have to say - I LOVE IT! Your program has made timing rowing head races very easy. It is easy to use, accurate, and probably the best feature is live results."
Gregg Hartsuff
Head Coach University of Michigan Men's Rowing
"We have been using RaceClocker for the past 4 editions of our annual ADR Regatta. Over the years we have seen it develop into a reliable and easy to use timing solution at very low cost. Among others live results and split times are what rowers enjoy at our event."
Giovanni Margaroli
Race Director ADR Regatta
"Thanks for a wonderful tool. We started using RaceClocker recently for our annual events as an upgrade from stopwatches, pen and paper and Excel sheets. It works smooth, simple, intuitive, accurate and easy. We spend a lot less time on post-race calculation and the live results are a bonus."
