To see the fish is ok but,,,,,,,
Joe,, Fish finders are certainly effective, and I've seen them on most stink boats.Remember you have to sort out which ones are going to bite and then which fish are the good eating ones and have the large bones that makes them easy to fillet. The kind of fish finder needed gives size and gender, which fish are active, and tells you the ones that are sleeping. Once you have all the facts now you switch screens to determine color of the lure, size of hook and and speed of the retrieve. If by chance this sequence does not develop and no fish to be found you will need to turn on the side scan sonar to locate your schools of fish. You have only till three O' clock in the afternoon and Monday through Friday to do this.Once the powerboat has run all around and uses up all the gasoline he can afford scaring the fish all towards the quiet sailboat, we simply hang a line out and " Bam "! we got our fish. How do I know? Been there done that.
