Connect a Garmin GT30 transom mount scanning transducer and a Garmin GT15M-IH, Airmar P72 or Airmar P79 in-hull mount traditional transducer to a compatible echoMAP CHIRP chartplotter/sonar combo.
This adapter cable allows the echoMAP CHIRP to continue to display water depth from the in-hull transducer in instances when the transom mount transducer loses depth reading due to cavitation.
