Use the Garmin Y Cable to allow the echoMAP series or GPSMAP 10X2xsv to display water depth from the in-hull transducer when the transom mount transducer loses depth reading because of cavitation. The Y Cable has a 12-pin transducer and eight-pin transducer to 12-pin sounder to connect in-hull mount traditional transducer to compatible echoMAP CHIRP chartplotter/sonar combo.
