I just printed and build my KM wiz wheel

. Trying your Passive Sonar Approach, joegrundman, I didn't work out how to adjust the observed change in bearing (after slowing down/accelerating) in the KM version. I have a version from KLH that has angle of bow on the outermost ring. On the middle ring there is range and speed. It does not have several bearing scales in the middle ring, as does your in-game version of the KM wiz-wheel. Is there a way to convert small degrees into the large 1-90° of my wiz-wheel or is there a new version that resembles the SCAF?
