Garmin Adapter Cable To Connect GT30 T/M to P729/P79

Connect a Garmin GT30 transom mount scanning transducer and an Airmar P72 or P79 in-hull mount traditional transducer to a compatible echoMAP™ chartplotter/sonar combo.

This adapter cable allows the echoMAP to continue to display water depth from the in-hull transducer in instances when the transom mount transducer loses depth reading due to cavitation.
