Sidevu Tuning

Going to be installing the Garmin 94sv this weekend on my the boat and wanted to know if anyone had any good videos explaining how to tune in the side/downvu? Ideally, I'd like to find something from Garmin, but anything on it would probably be helpful at this point. Also, if anyone has tips/pointers, they're greatly appreciated!

You tube is loaded with tutorials for all makes and models.

Turn it on and be amazed at what you see, transducer placement is the key for any unit.

Any specific tips?
