I am trying to get everything in my mind for my upcoming boat purchase...I will be installing Garmin electronics and I was wondering if it would be better to have a dedicated unit to run the livescope? I was thinking about having a 10" for the regular sonar and a 9" dedicated to the livescope only? Or can I have just the 10" for everything? Most likely going to be on stick steer boat if that matters. TIA
