Overview

This Y cable is designed for anglers who want to run a MEGA 360 Imaging transducer alongside an external 2D/MDI transducer on a compatible HELIX fish finder. It provides a practical way to combine those transducer connections through a single setup, helping keep the system organized at the console or bow. For users building a Humminbird electronics package around compatible HELIX units, it supports a more integrated installation without changing the core transducer choices.

Considerations & Trade-offs

  • Requires a compatible HELIX fish finder to use as intended; it is not a standalone accessory.
  • Designed specifically to connect a MEGA 360 Imaging transducer and an external 2D/MDI transducer, so it is only useful if you already run that combination.
  • Function is limited to cable connectivity; it does not add sonar features on its own.
  • Compatibility is product-specific, so matching it to the correct HELIX setup is important before purchase.
