Beep, I agree with you.
The manual is simply not meant for bedtime reading, it's simply so sterile with no real world examples and as you say, is full of cross-referencing & duplication, but with a book like Scott's Sonar Power book, you can take it anywhere you want and read it like you would a novel.
I DO find the online help useful at times when I just want to check or look up something, I think this is it's best application.
