Shane Compain offers a masterclass on reading SideScan. SideScan is offered in Simrad displays ranging from 7" right up to the impressive 24" NSO evo3 used by Shane.
Why do you keep pointing to the side of the boat and saying, "there is the fish" when the chart shows the history? It would seem that you should be pointing behind the boat to about the 4:00 o'clock position and saying, "there is the fish". Of course this is only true if the ducer is installed on the back of the boat. Was the ducer installed on the trolling motor up front on the bow???
