SpeedCoach Overview

Waterproof, buoyant and durable, the SpeedCoach provides you with all the information you need to train and race effectively. Take your training to the next level with the SpeedCoach system from NK. Instantaneous boat speed readings will tell you exactly how fast the boat is moving and give immediate quantitative feedback on personal improvement, technical changes, rigging adjustments or seat race switches.

The SpeedCoach is an excellent training tool for any small boat, and is also an excellent complement to a Cox Box Mini or Cox Box amplification system in coxed boats, giving coxswains quantitative feedback on boat speed as technique and power calls are made. Elapsed time and stroke rate readings guide workouts, and average speed and memory recall allow you to review your performance over a piece or race in detail.

The optional seat switch allows you to remove the speed sensor if desired (such as for races) and still have accurate rate information.

No through-hull holes are required for installation.

Includes: Protective Bumper in personal choice of color, 1 CR2032 Battery, Lanyard, Carry Pouch.

Requires: SpeedCoach Wiring Harness, Mounting Bracket (T or Angle) and Speed Impeller.
