I am on the list to get a Active target, but I have to upgrade my unit. My question is to those that already have AT will a 9 inch HDS live work well with it or would u guy recommend going with a 12 inch? I have a 9 inch HDS touch that I am going to leave up front to use for sonar and maps and the new unit only for AT. Anyone running it on a 9 inch? Would u invest another $1000 to get a 12? Thanks for input
