I'll apologize in advance, because I'm not familiar with Garmin's units. I currently have a Humminbird Helix 9 MEGA at my console and an older lowrance unit at the bow. I love what I've seen online from the LiveScope and I'm thinking about possibly replacing the Lowrance unit at the trolling motor. I fish mostly shallow water (10 feet and less) and almost never use the Lowrance for anything other than telling my current depth and water temp. If I got the LiveScope transducer for the trolling motor, I wouldn't care about side imaging (I have that on my Humminbird) or traditional sonar. What head unit would you recommend getting that would be 8 inches to 10 inches that would work well for the LiveScope? Thanks!
