Cox-Box Mini

Rowing’s original waterproof timer-amplifier now has a little sibling with overmoulded connectors for protection from wear and brightly colored rubber bumpers for durability and easy identification in the boathouse and at team events. Ideal for use with the SpeedCoach GPS 2 for instantaneous stroke rate and split.



Compact, Affordable Voice-Only Amplifier: The CoxBox Mini provides voice-only amplification in a compact product designed to be used on its own, or in partnership with NK performance measurement products. The affordable price point lets you purchase multiple Minis to meet your needs, and gives Coxswains the option to own their own. Flexible Wearing Options Keep your Hands Free: The Mini is designed to be worn, keeping your hands free. A rugged rotating belt clip allows you to attach it to your clothes or gear bag strap, and the optional armband is perfect for coxswains.
