I got this one: http://www.ebay.com/itm/hot-compass-ther...=item5b079fca13 In the woods, it points in the same direction all the time, and keeps me from going in circles. I have another cheap backup in my pack, that points ~5 degrees clockwise compared to it.
At the bottom of that ebay page, the description reads "Affected by quartz magnetic field,thermometer and compass can not normally point out the direction,it belongs to decoration".
Ahhh, I see. A compass that challenges your nav skills. That's Awesome!!! grin
At least it was consistent? I'll have to double check that, again, compared to the other compass I was carrying. I tried it at least 5 different times, and was satisfied enough to put the other compass away.
The thermometer is definitely off, unless I take if off my wrist.
edit: I've been playing with both compasses indoors. They both tend to point north most of the time. I think there is too much interference in a house. However, they do about the same: both the watch/compass and the compass.
edit again: The third one I have, is in my cell phone (a galaxy note, which I presume functions like yours, billstephenson). It isn't as much of a pain as the cheap mechanical ones, that require manipulation to overcome friction.

You know I had to take a magnet and wave it around that magnetometer. It's really pretty cool, I could just wave my had over it and move the needle on the screen. When you apply that same method to something like robotics you could, in theory, steer a remote vehicle that way, or move a camera.
But.... when I got the magnet too close it totally crashed my app

Try using a quartz watch, instead of a magnet. It has a some effect if you hold it really close.
