When the unit is in manual mode, you may not receive any depth readings, or you may receive incorrect depth information. Fishing mode Enhances the performance of your unit by providing preset packages of sonar settings geared to specific fishing conditions. For more information about fishing modes, refer to the Basic Operation section. Reset fishing mode Resets selected fishing mode to default settings. That is useful when you want to clear settings adjustments made while using a fishing mode. Installation Installation menu Keel offset All transducers measure water depth from the transducer to the bottom.
