Garmin 0101244533 Transducer Y Cable

Connect a Garmin GT30 transom mount scanning transducer and a Garmin GT8HW-IH, GT15M-IH, Airmar P72 or Airmar P79 in-hull mount traditional transducer to a compatible ECHOMAP Plusâ„¢, echoMAP CHIRP chartplotter/sonar combo or a GPSMAP 10X2xsv/12X2xsv chartplotter. This adapter cable allows the above units to continue to display water depth from the in-hull transducer in instances when the transom mount transducer loses depth reading due to cavitation.
