Calibrate Speed

The speed sensor can be calibrated to compensate for inaccuracies. Be- fore you change the setting, calculate the percentage the speed is off. You will enter this percentage in a moment.

If you figure the sensor is reading 10 percent faster than actual speed, you will enter -10 in the calibration window. If the sensor is reading 5 percent slower than true speed, you will enter + 5 in the window.

A good way to gauge your speed sensor's performance is to compare its reading with the ground speed measured the GPS function. When you make a run to compare GPS ground speed to speed sensor speed, per- form your test in relatively calm water free of current, if possible.
