Good morning SU fishing fam, I’ve got an electronics question as I’m new to them. If I have a graph mounted at the helm and I want one on the deck; do I need a transducer for the one of the deck if I plan to use activetarget is that right?🤔

Good morning fishing crew I’ve got a question I’ve been bouncing around in my head and thought why not ask the crew and get other opinions: I’ve got a 87 ranger 363V, my steering cables need to be replaced. I’ve been bouncing the idea of upgrading to hydraulic steering but not sure if I want to pull the trigger; any opinions on upgrading or staying rack and pinion would be greatly appreciated from the community.
