Humminbird EC M30, 30′ Shielded Extension Cable

HELIX extension cable is used to extend the transducer cable an additional 30′. While there may not be any major performance issues while using the existing, non-MEGA EC W30 cable (720003-2), there is a possibility of interference. The new cable includes additional shielding and twists to eliminate interference.WARNING: Cancer and/or Reproductive Harm. See
