Title: Not accurate enough to be worthwhile
Review: I am disappointed with this compass. The directions for calibrating it are ambiguous, and it took me several tries to get it to agree that it was calibrated. That having been done, it seems to display "distortion" and incorrect heading information about 20% of the time. Further, even when it thinks it is accurate, it is often at odds with what I know to be the accurate direction -- not totally off, but showing W when we are going almost directly NW, for example. And it has no provision for accuracy beyond the eight directions that it can show with two letters. I will be replacing this with something else.
