Make better calls.

Motivate a faster crew.

Make sure every word is heard from bow to stern.


Control the pace of the boat. Monitor the stroke rate. Motivate your crew. And when you’ve finally reached the point of exhaustion, dig deep, push beyond and rely on your CoxBox to tell you the precise moment to make the call that brings your crew to victory.



The coxswain is the voice of the boat. If that voice can’t be heard, your crew can’t execute your race plan. Your commands must cut through the noise right to the ears of your crew. Make sure your words are heard from bow to stern. Depend of the audio amplification of the CoxBox to help keep your crew focused, motivated and hungry for the win.


You need accurate information to control the pace of the boat and to make the calls necessary to help your crew keep cadence. The CoxBox provides accurate and immediate performance monitoring, including stroke rate, stroke count and elapsed time. In order to be a good communicator, you need dependable and reliable data at the precise moment you’re making a call.

Redesigned according to YOUR requests: switch and replace batteries in seconds and see your charge remaining. Wrap-around bumpers make your CoxBox yours, and darn near indestructible!
