Garmin Y-cable (12pin transducer + 8-pin transducer to 12 pin Sounder)

Model: 010-12445-33

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 Plus, echoMAP CHIRP chartplotter/sonar combo or a GPSMAP 10X2xsv/12X2xsv chartplotter.

This adapter cable allows the ECHOMAP Plus, echoMAP CHIRP or GPSMAP 10X2xsv/12X2xsv to continue to display water depth from the in-hull transducer in instances when the transom mount transducer loses depth reading due to cavitation.
