MKR-MDI-1 Humminbird HELIX MDI Sonar Adapter Cable
Connects your Humminbird HELIX fishfinder to a Minn Kota motor with built-in MEGA Down Imaging.
Shielded cable for crystal-clear MEGA Down Imaging sonar performance.
- HELIX 8 G3N
- HELIX 9 G2N*/G3N
- HELIX 10 G2N*/G3N
- HELIX 12 G2N*/G3N
The built-in transducer cannot supply MEGA Down Imaging to Humminbird models that do not already have the capability. If you have a G2/G2N or a G3/G3N HELIX that is not a MEGA SI or MEGA DI model, you will still get 2D CHIRP Digital Sonar from the transducer.
*HELIX G2 and G2N units need to be running the latest software update to view sonar from Built-In MEGA Down Imaging motors.
