The SOLVE TVMDC calculator will correct magnetic compass error and make magnetic compass correction thus correcting variation and deviation of the magnetic compass. The calculator also converts relative bearings to true bearings and gives reciprocals. ... A simplified explanation of true course, the magnetic compass,
