I use a Reading Edge for reading of long documents or books. In my reading of a Bible study book, I found that every once in a while, the Reading Edge would mix things up a bit. I knew the book was in one column, so the next time that occurred I looked at that page with my optacon and found that the author had put little blurbs in the margin. I couldn't do much with the scanner, but I could look at the format and from then on I could interpret these, or if they got too confusing I could read that small part with my optacon. Without an optacon, I'd have had to ask for sighted help, something I don't like to do and wouldn't have bothered unless these notes confused me to the point where I couldn't understand the main points of the text.
