NOTE: Minn Kota motors with built-in Universal Sonar 2 (including those with i-Pilot Link) are not compatible with Humminbird's Down Imaging Sonar. An external XTM 9 WIDE DI 20 T (83/200) or XTM 9 DI 25T (200/455) is required for all sonar readings with all HELIX 12 , HELIX 10, HELIX 9, 1100, 900, and 800 Humminbird Down Imaging units. An external XTM 9 DI 25T transducer would be required for the Down Imaging versions of the HELIX 7 and HELIX 5 along with the 788ci HD DI.
