This compact version of the original Arc Jet compass is perfect 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 plate. It has a clean, fixed capsule without distractions which provide lots of transparency and increase the map visibility. For more detailed map reading, you can get the Arc Zoom C magnifier as an optional accessory. The Zoom is easily attached to the baseplate of your thumb compass. Due to its functional design it becomes well integrated with the compass.
