You can hook up the 8 and the 9 with the Lowrance Ethernet cable. Both will share one transducer. That way you don't have to have one on the trolling motor and wont get any sonar interferences. That's what I just did with my HDS8 in my console to a Lowrance LMS 520c at the bow. My LMS 520c is actually ethernet to my structure scan transducer. I haven't been able to test it out on the water yet, but when I turn on the units on land, it is getting feedback from the transducer. Now I just need to figure out how to get them to share the GPS antenna.
