True, but the Garmin 62s handheld that I use for geocaching and hiking ($200-$400) has a 
3-axis, tilt-compensated electronic compass that shows your heading even when you're 
standing still and holding the unit upright or at an angle. Accuracy is +/-2° except 
near the poles where it is +/-5° . My Casio watch on the other hand is +/-11°, if you 
hold it level.
