Arc Jet C is the compact version of the original Arc Jet compass and fits perfectly for smaller hands. The compass comes with the same exclusive Silva Jet 2.0 high performance needle as the Arc Jet. It has the same capsule size and quality as the original, but with a smaller thumb rest. This is a left version. The Arc Jet C has a clean, fixed capsule without distractions which provide lots of transparency and increase the map visibility.
