Assuming that you have two depth finders on your boat. How many puts the more expensive and better one on the front at the trolling motor?

My situation is this, I have a 200DX Humminbird already mounted at the steering wheel. That is a pretty good depth finder...works well. I ordered a Humminbird 565 last week. Do I have a good argument to move the 200DX to the trolling motor and mount the 565 at the steering wheel? I am not the most mechanical person in the world, but would attempt it if there would be a world of difference. Thanks for any opinions.
