Since 2006, Cool River Systems has been a pioneer in the development and production of hand-held wireless timing systems for competitive sports and training. Driven by frustration and inaccuracies experienced at local swim meets, we designed the first wireless stopwatch system for this application.

Since then, our patented timing systems have been used in a widerange of sports, including swimming, track, and cross country. The versatility and accuracy of our products have allowed us to work with teams and organizations at all levels of sports from youth to professional. We design products to combine extreme ease of use and low cost with high accuracy and performance to enhance the total experience of the competitors, officials, and spectators.
