9 M360 2DDI Y – MEGA 360 & 2D/MDI Y Cable

Humminbird 9 M360 2DDI Y – MEGA 360 & 2D/MDI Y Cable lets you run MEGA 360 Imaging together with an external 2D/MDI transducer on a single compatible HELIX head unit. Clean rigging, one port used, and full sonar coverage so you track structure and fish without swapping cables.
