As the other guys have said check out bass boat central, there are 2 hummingbird boards to help you.
Doug v also has a great selection of videos on youtube
ben parker has a dvd called bass under glass unlocking mega schools which is a great resource for humminbird users. I watch it several times a year.
Also, call around to some local boat dealers, most of the dealers i know have an electronics rep on hand at least once a year to answer questions
