This Garmin adapter cable lets you run a GT30 transom-mount scanning transducer alongside a GT15M-IH, Airmar P72, or Airmar P79 in-hull traditional transducer on a compatible echoMAP CHIRP chartplotter/sonar combo. When the transom-mount transducer loses depth readings due to cavitation, the unit continues displaying water depth from the in-hull transducer — keeping your sonar data uninterrupted.

Specifications:

• Compatible transducers: Garmin GT30 (transom-mount scanning), Garmin GT15M-IH, Airmar P72, and Airmar P79 (in-hull traditional)
• Compatible chartplotters: Garmin echoMAP CHIRP series
• Function: Simultaneous dual-transducer connection via single adapter cable
• Cavitation fallback: Maintains depth display from in-hull transducer when transom-mount loses depth signal
