Calibration Routine
To calibrate the SpeedCoach, row over a measured distance on still water (on flowing water, row both up and down stream and average the results shown on the display). Then, use the following formula to obtain the new calibration value:
(Old Cal Value) (True Distance)/Displayed Distance= New Cal Value
For example, if the known rowed distance is 1 mile, but the display shows 0.92, the calibration value would be:
(1.00) (1.00)/0.92 = 1.086

Overview
Take your training to the next level with the Speed Coach 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 Speed Coach is an excellent training tool for any small boat, and is also an excellent complement to a Cox Vox or Cox Box amplification system in coxed boats, giving coxswains quantitative feedback on boat speed as technique and power calls are made.
Boat speed through the water is
accurately measured and clearly displayed, together with stroke
rate and elapsed time, distance or averaged speed. Rowing on moving water makes it uniquely difficult to measure your improvement over a stroke or over a piece. NK's proven speed impeller won't ever mislead you the way a land-based time or speed measurement can.
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.
Choose to display either meters, kilometers, miles or nautical miles. With each power up, the unit also displays the total distance rowed since the last battery change, providing a running training log.
The display unit is waterproof, bouyant and durable
and the speed sensor is low-drag and resistant to fouling.
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.
