I love my HDI transducer on the front with my touch 7. I get supperior sonar, and Downs Scan right from the front. If I ever want side scan while im on the trolling motor, I network to my LSS2 on the back of the boat. Yes its 20 feet behind you, but you dont have to deal with interference or slop from the trolling motor. If i see something i want to go back and fish, I just drop a wpt right on the structure, spin around and line up with my Point-1 GPS. Its a sweet system.
