NK's new CoxBox Core™

CoxBox Core

Completely redesigned, CoxBox Core retains the main functions that coxswains have come to rely on, and surrounds them in a more powerful, efficient, streamlined form.

The CoxBox Core features a host of innovations including:

Easy to read display

A single-piece faceplate and large, easy to read display provide a more rugged and waterproof design.

Waterproof interface

Buttons are precisely located and sealed from the elements, reducing the potential for water to enter the unit. The lower profile design takes up less volume.

Longer battery life

New cylindrical battery design provides 10+ hours of battery life with a more reliable, sustained charge.

Wireless Stroke Rate

No more dealing with sensors or magnets.

Monoblock™

Monoblock™ connector port relocates microphone, speaker/charging and data ports away from the face of the unit, creating better readability and simplified serviceability.

Stablesocket™

Stablesocket™ design prevents rotation and bending of plug inserts, which protects pins and sockets from damage.
