Thanks guys I was talking to a friend and that’s what he told me too. Makes sense that it follows the GPS not the transducer readings that would get messy when you think about it.

Hi,
New to Hummingbird and Ulterra. Have setup question can’t find in book. I set my Helix 10 mega chirp up to use my current lowrance high speed transducer for 2D and moved my Lowrance up front and connected to the Minn Kota transducer on the Ulterra. Question is will the Lakemaster follow contour work that way? Or does the Hummingbird have to use the transducer on the Minn Kota?
