I just bought a new Helix G3N SI GPS and also the new Ipilot link with built in Mega DI transducer. I want to mount the SI transfer to the head of the trolling motor. Can anyone point me to the right transducer saver that will work for this. I had SI on my old terrova but with that built in Mega DI I want to make sure I get the correct one. Thanks for the help.
