I plan on making the trip to Bass Pro tomorrow evening to buy a new Garmin Echomap Plus fish finder. I have a small jon boat type of boat. I sit at the stern with my tiller 10 horse motor and trolling motor. I like to long line. I don't have a lot of extra room for things so I was planning on getting the 73sv. Will I be disappointed with side imaging on a 7 inch screen? It will be very close to me.
