Has he tried re-calibrating the compass? It almost sounds as if the compass is not really calibrated for all headings. It’s important to get as many orientations as possible during the calibration process so the Cobalt can find the true magnetic vectors. Is there anything in his dive gear, like a magnetic octo holder, that could alter a magnetic compass on some headings? I haven't heard of an issue like this, but that's not to say something odd couldn't happen. If this persists after calibrating, I can send you information on a diagnostic mode for the compass that has an alternative option for calibration.
