Structure Scan HD on Ulterra?
First off you can NOT network a Hummingbird to a Lowrance.
I network all 3 of my Lowrance units to the rear Structure Scan ducer. The problem with it on the TM is that you constantly change the left and right when you turn the TM. You can make or buy a transducer mount for the front that folds out of the way separately from the TM. I was going to do that on my boat, but decided to just waypoint the cover or structure and go back and fish it with my GPS, sonar, or a marker bouy.
