I fitted a Ritchie compass to my bike a while ago, and I find for my needs it works very well. I use it mostly in support of my preplanned route, i.e. checking I am heading in the right general direct as I progress toward way points (town, crossroads etc) I have listed. When I first started using it I plotted bearings from a map, but soon realised this was unnecessary since following roads or tracks is not like following a straight path from one point to another as I imagine you would at sea, in the air
I find I get best results if I am riding at a steady pace and by mounting the compass on my bike screen it gives acceptable accuracy and does not appear to be affected by the bike's electricity. Interference from the bike's iron components can be compensated for by adjustments made to the compass when you are setting it up.
