Can anyone recommend a good book/video on interpreting sonar? Thanks.

Here is a great link to start. Even though it's from Lowrance, it applies to all.

I think the guys name is Wilson Frazier.  Theres a few short videos on youtube with him. I think he has a book or DvD as well as seminars that he does.

Use the internet though. Theres a gross amount of information on a million different sites about sonar and how to read the display. After going through them, you'll start to notice that a lot of them offer pretty much the same info. Jot down some notes as you read and you'll start to understand the important parts.

Yup!  Thanks for fixing the link!

Thank you all for for helping out.

Sure thing.

By the way, make sure you install the transducer properly or none of that great info will really mean a thing.
