Davey,

The Speed Offset configuration setting may be found within the MFD's Transducer Settings (MENU->FISHFINDER SET-UP->TRANSDUCER SETTINGS->SPEED OFFSET). The MFD does not offer a feature to set Speed to SOG. It is recommended that the Speed Offset be applied under slack current conditions, where the offset may be adjusted until the value reported for Speed matches that of SOG. As paddlewheel speed through water sensors have non-linear error associated with them, the reported speed will be most accurate at the speed at which the sensor is calibrated. Accordingly, if seeking accuracy when trolling, the the vessel should be operated at trolling speed when adjusting the Speed Offset to match SOG.
