Frequently Asked Questions

The SpeedCoach is factory calibrated to provide reasonably accurate performance in most shells IF the impeller is installed approximately 16’3” (5m) from the bow. Calibration is an optional step, which allows the display unit to compensate for different impeller locations and to perform very accurately. You do not need to calibrate your system if you are only concerned with comparing performance on a day-to-day basis. However, calibrating your unit will make certain your splits are accurate.
