James Lindner and Jeff Simpson are out on an unmapped river doing some catfishing. A great feature of a Humminbird Helix for unmapped waters live, this is using Humminbird's AutoChart Live to create contours on your map. You'll need a Zero Lines SD card to save the map to your unit. This works well in all bodies of water, from rivers to big lakes. You can create richly detailed maps of your favorite fishing spots in real-time with Humminbird's AutoChart Live, a free feature available with all GP

Do you have a favorite fishing spot that isn't mapped? Create highly detailed maps in real-time with Humminbird's AutoChart® Live. Your compatible HELIX or SOLIX unit will come equipped with 8 hours of internal storage, so we recommend using a Zero Line Card to store years worth of AutoChart Live data.
