Looking at getting a new depthfinder. Probably a HB with SI. Questions are ... which model do most on the board use (have terrova I-pilot)? Do you have transducer mounted to trolling motor or transom? Have read the US2 will not work with SI so will not be using or can you use both? I have found a thread on here that shows how to mount to trolling motor, just wondering how much does movement of motor affect imaging.

Thanks Grant
