The MinnKota MKR-MDI-2 is a 30-inch shielded adapter cable that links a Humminbird HELIX 7 G3 or G3N fish finder to a Minn Kota trolling motor with a built-in MEGA Down Imaging transducer. It carries the MEGA Imaging high-frequency sonar signal, so you can see fish apart from structure and read their orientation. It is a single-purpose part: it only matters if you own both a compatible HELIX unit and a MEGA DI-equipped Minn Kota motor. Buyers who needed it report a clean fit and a working connection; the main gripe is that it is a small, specialized cable you cannot substitute.

Buyers who needed this cable say it fit and worked, linking an Ultrex with MEGA Down Imaging to a Humminbird HELIX 7. The only recurring complaint is that it is a specialized part with little competition.
