Does anyone know of a good video, book, or seminar that is useful to the ins and outs of using a fish finder. I get so frustrated every time I try to use mine, haven't of clue what I'm doing. I know the brand is Eagle, and it was a fairly decent one, but it is probably 5 or 6 years old. Don't have access to the model number right now.
Thanks for any suggestions. I live in the Springfield Mo area.
