This Garmin adapter cable lets you run a GT30 transom-mount scanning transducer alongside an Airmar P729 or P79 in-hull traditional transducer on a compatible Garmin echoMAP chartplotter/sonar combo. When the transom-mount transducer loses depth data due to cavitation, the echoMAP seamlessly continues displaying water depth from the in-hull transducer — keeping your readings reliable underway.

Specifications:

• Connects a Garmin GT30 transom-mount scanning transducer to a compatible Garmin echoMAP chartplotter/sonar combo
• Also connects an Airmar P729 or P79 in-hull traditional transducer to the same echoMAP unit
• Allows simultaneous use of both transducers on one compatible echoMAP device
• Maintains water depth display from the in-hull transducer when the transom-mount transducer loses depth reading due to cavitation
• Compatible with Garmin echoMAP chartplotter/sonar combo units
