That is interesting and good news. At the 60CSx price point I am guessing it's a pretty cheap magnetometer which means that it should work for me too. The calibration I will have to do from the software but that shouldn't be too hard to figure out and the true north vs magnetic is, in a word, trivial. At least when you happen to have a GPS with you.
