for us, the compass was really useless, and wasted quite alot of our time. it is just way too sensitive i guess. ours were mounted on a beam for testing purposes, 10 inches away from the motor and brick and battery. it works, but not precise enough to be of any use. and what more, is that the exact same program would work on one side of the field, but not the other. and the field is at least 2 feet away from any walls.
