How to catch UNMARKED fish on the St Lawrence River! Forward Facing Sonar (I don't have it)

You can still catch fish on the St Lawrence River without Forward Facing Sonar. Because the St lawrence is so big sometimes we don't know where to start. I suggest you start on shoals and if you pick the right shoal you can catch a 25lb bag on 1 shoal. Whether you mark fish or not believe they're there, these shoals are massive and hold fish!
