At just about every boathouse and regatta in the world, coxswains can be seen sporting the signature NK blue head band and microphone while carrying the small stainless steel display unit.

The Cox Box is the product that started it all! First made in 1978 by Paul Nielsen and Richard Kellerman in a New York basement, the Cox Box system by NK has been helping coxswains, crews and coaches ever since.

Considered by rowers all over the world to be essential equipment in any coxed boat, the Cox Box shows time, stroke rate and stroke count while providing a powerful amplifier and speaker system that ensures that the coxswain's voice will be heard in every seat in the boat.
