If you get a liquid filled compass, complete with the adjustment screws (+
instructions) and have access to true N-S, E-W roads or tracks on which to set
it up, it should be OK. Mine took me about 30 minutes of fiddling with the
screws and re-checking, before I was satisfied with the adjustment. After that
it was fine until the next summer's heat screwed up the liquid fill.

I now use a Garmin GPS12 - it's OK providing that I'm moving or have recently
come to a halt.
