hi all,,,also been looking into the side imaging 797,,,what i think alot of people are getting confused with the side finder or side sonar,,,which is along the same lines,,the side imaging is newer technology,,,and personally i think that this might be the way of the future for sonars,,,if you look at the way the picture is processed and i am sure it might take some time to get to understanding what your looking at,once you do any information gathered is going to help catch more fish!!
