From what I remember, I think a reading in .600s and .700s is fine, that's normal. Much higher or lower, and you have other problems, and they go beyond fishing!
When setting up my BB, my natural voltage readings were around .400. Reading the book, it listed out a bunch of possibilities, but most likely was dirty zincs, so not doing their job any more. In searching it out, found out a more significant issue -- my new to me motor didn't have any zincs at all. Added one, and voltage was in normal range.
The other biggie I understand is power leakage from things like bilge pumps, transducers, ungrounded manual start kicker motors, anything electrical in contact with water or boat bottom. As someone said earlier, if your readings are "hot", then you start with everything off and turn things on one at a time to isolate which one is a problem, then ground it once you know.
